Gear diff

[Robocop]

Anyone know if its going to be available soon only seen aug-sept due fir release same time as rtr 22 would like it for f2 finals

[Gnarly Old Dog]

Not saying that it definitely won't come in but with the F2's now less than a week away, I believe you will need to be prepping your car to run the ball diff.

In all honesty, no availability date can be guaranteed until the part is in stock which, when I checked last Friday, it was not.
I wouldn't expect to see the diff until at least the 22RTR is in the shops so I would use that as the initial indicator.

Sorry if this disappoints - but at least you still have 5 days to prep your car accordingly for the event next weekend.

See you there :-)

[rcjunky]

You could always run the AE gear diff out of an SC10, B4.1 or T4.1. I just set my new car up this way and will be trying it out this Wednesday. I think it will need to be worn in before it starts running good though as the tranny is a bit stiff (its 1 extra tooth), but running it in for a while with a drill helped, I think a race night should loosen it up. I never put any shims in for side to side play in the mid motor trans but some say its needed.

[baldric1983]

why would you put a bigger gear in there just wait for the losi gear diff don't ram something that wasn't made for it in there?

[rcjunky]

because I wanted a gear diff now, and many others have done it...

[Fred79]

Ok first of all you don't have to ram it in there, it's only 1 tooth more than stock :p mine fit's perf. and loving :wub my AE sc10 gear diff. So don't worry and buy one already, you will never go back I tell you...
Yo will also need som 10x12x0.2 shims 4 on each side of the diff for countering play... ;)

[rcjunky]

mine didn't even need shims in the mid motor case and it has no play.

[Ross]

Any news on the gear diff.

[kayce]

Any news on the gear diff.

I've seen some of the individual parts available, but not the complete diff (yet).

[AndyPk]

I'm fed up with waiting for the losi unit which is now 3 months 'late' so have ordered a SC10 diff. What weight diff oil are you guys running?

[Fred79]

On carpet i would run 2000 to 3000 depending on setyp and track. same on astro.

[FoarGeez]

Hi guys, so if we were to use the SC10 gear diff we should get all this 3 items to run in the 22?

1. SC10 diff gear & cover

2. SC10 gear diff rebuild kit

3. SC10 gear diff outdrive

[rcjunky]

nope, you want the complete diff

The losi one is currently availabe as well. They were all in stock yesterday on amain.

But the other side of the gear isn't listed yet...

[kayce]

The losi one is currently availabe as well. They were all in stock yesterday on amain.

Even at amain, those parts have been on backorder for quite a while.

I think the part # people will be looking for is the "gear diff complete" = LOSA2954 - it'll be cheaper than buying individual parts bags also.

[ed gaines]

anyone try the gear diff on dirt?

[Darren Boyle]

The 22 RTR kits arrived into stock this morning, so we we now expect the gear diffs to be here later this week with the spares delivery......

[B4 Sloth]

Fingers crossed they are here ready for stotfold:thumbsup:

[Mau]

Do this diff mount on mid motor configuration too? Is it ok for carpet or not? I come from 1/8 gas so ball diffs are not so friendly to me.... :(:(

[kayce]

yes, of course

does the 22 rtr geared diff need to be greased or oiled if so with what? will the clear diff grease for the standard diff be ok????:eh?:

Ps got mine from DMS Racing if you're interested!!

[B4 Sloth]

Got mine from dms, with some Hiro seiki metal gear grease. Will be building it up over the next couple of days or so;)

Ps thanks DMS:thumbsup:

[No. 46]

Jay you could do with some diff grease in there but without running it yet i can't recommend anything as yet, although i would imagine something fairly thin is best so leass than 5000wt

Cheers

George Fairweather

[racingdwarf]

I agree, rallyx diff oils, anything above 5000 starting to get very heavy.I will prob start around 1000,2000:thumbsup:

[millser]

hi what advantage will the gear diff give you????

There is none, it's just the low maintenance option for those that don't maintain their cars that don't notice the benefits of a balldiff.

[millser]

ok so why is everyone raving on about when they come out

[kayce]

ok so why is everyone raving on about when they come out

Because they can't build a balldiff, or just don't know any better. :lol:

[jayropes]

feels a hell of alot smoother to me but what do i know i'm just a spastic that cant build diffs!!

[No. 46]

Your just to fussy Jay:p

Lower maintenance sounds like an advantage to me, and it should be more consistant if it seals well. The losi diff does needs very regular maintenance to keep it tip top, even with decent balls.

Every diff needs regular maintenance to keep in top top, even a gear diff. ;)

[B4 Sloth]

Has anyone run the diff yet?

Built it up with metal gear grease, anyone used diff oil?

I have built mine up but need to tighten the screws, what size hex driver...cannot get to the back of the garage to rifle through my stuff ...got a feeling that the screws are imperial.

[drop4205]

prob gonna be 1.5 mm wrench. I would put 3000 wt diff oil in it to start

[B4 Sloth]

I was told it was not a proper sealed diff, although quite clearly the number of rubber washers indicate otherwise. Still lighter than a ball diff using the grease.

[drop4205]

it should be a properly sealed gear diff but the looks of the orings

[FoarGeez]

my ball diff have been running well after i change it to ceramic balls but this thing just arrived from the LHS and i just have try it oiled and run it outdoor track n see how it goes over the weekend..

oh dear god! metal gear grease? diff oil. anything between 1 and 7k depending on grip levels at your track. less viscous for less grip

probably a .50 imperial driver knwoing losi gear diffs

And for those who "dont" wish to run diff oils and constantly change them to suit conditions/driving style, "metal gear grease" will work just fine. Serious racers will use oils (and/or ball diffs of course) occasionl or club racers or even bashers may well prefer a standard "fit and forget" grease (as supplied in the RTR's).....

We have had a 40/60 split of customers wanting to just build the diff "once" and never see it again (thats the 40%) and if that suits them what is wrong with that?

Early indications form Losi were that it was not even going to be a sealed unit when it arrived which would have meant grease only but as it turns out they deciedd to make it sealed.

[jaywestwood]

I totally disagree with you here!! gear diff gives a totally different feel and will aid rotation if it is built and set properly... standard diff's are good if kept on top off but gear diff is loads more consistent and as darren says most occasional racers will love the fact they dont have to rebuild it and then adjust it... 1 less thing to do track side

if they dont want control ove how it handles then fine.

but if they want a solution where they can put it in and leave it then losi is not the way to go. certainly not when it comes to their diffs! every losi gear diff i have had cooks whatever is in it within 10 minutes.

I used to have 4 sets of diffs for race days. even the 3 for 5 minute qualies were black inside after just 5 minutes.

is there anywere in the uk you can get the 22 gear diff ?

Any Losi stockest should be able to get you one, and I dare say Darren at DMS has lots of them waiting just for you.

Mine gets it's first runs tomorrow, should be interesting.

[TKG26]

pick mine up monday, racing it wed ;)

[cryer-evo]

Brought one last night from dms so what sort of oil should i get for it I run on astro and carpet high grip

[ronny191]

Just build mine up yesterday, gonna try it out today at the local track.

i race on a very high grip astroturf track, but the weather may cause some rain so i assume its gonna be slippery.

build it up with 1500 wt oil to start, and go from there.

only downside ive seen so far is the use of 0-rings instead of bearings on the drive cups. its feels it has some resistance because of it, but i guess after one pack this should go away.

im not so great with building balldiffs myself, and im used to geardiffs.
consistency should be allot better, but on a high grip astrotrack i must first see if it drives better. i hear a ball diff seems easier to drive...?

but the less maintenance is by far the no. 1 reason i got the geardiff.

[FoarGeez]

Over the weekend ive tested the gear diff with a #2000wt at an outdoor track. Condition changes from wet to dry over the day due to rain on the night before. and this is just my simple newbie conclusion;
Geardiff = for those weekend bashers that just simply wanna have fun without having to sit in the pit more then spending time on the track
Balldiff = serious racers that wanna get that podium finish

[cryer-evo]

So you didn't like it what did it do to the car for handaling and did you try any different oils in it ?

[B4 Sloth]

Surely on a 2wd car it is not going to make sooo much difference? Or am i wrong?

I mean, once decided on your weight oil are you really gonna change that much? I know that once i have a diff set right it is set right. Nice lightish oils for most i would have thought, its not a 4wd after all and certainly not got the grunt of nitro where it may be more important.

[FoarGeez]

will probably get lighter oils such as 1500wt or 1000wt.. but thats just for fine tuning and making it easier to drive. currently im happy with the #2000wt oil setup just the car suffers abit on exiting corners. will do try keep an update here as i go along..
bottom line, geardiff is a worth to buy for those lazy asses like me. n i keep myself busy on other parts of the car now :D

The car suffering on corner exit is not diff related. It's poor car design leading to too much camber gain caused by too much body roll. Or at least that's the next theory we are testing with mine anyway

[Mau]

That's interesting cause I've noticed too 22 suffers of excessive body roll exiting corners (carpet) it seems nearly impossible to calm down this, I tried diferent camber angles, camber gain, but not satisfied. It turns and then it seems to stop for a while elevating internal wheel. I know this is a diff 3d but however....:(:(:(:(

Tried putting your shocks all the way out on the arms?

[jaywestwood]

Tried standing the shocks up on tower or stiffer spring's? also shorter camber link on rear? a diff wont change direction change on a car but lighter diff oil will help it rotate and will give me grip

[Mau]

Hi, I'm not a newbie so tried camber links (short/long) and of course shocks positions.
The problem is more due to excessive grip I suppose will try with a swaybar.

A diff can help turning too, if the inside rear wheel has not traction (due to it's lifted) and the outside has the load and the diff is too light the car has no traction.

Thanks guys, will try something and be back however I agree that on high grip tracks a gear diff will suffer less than a standard ball diff.

[steveproracing]

If your inside rear wheel is lifting then your front spring is too soft. Simples!!
Nothing to do with diffs etc it's to do with too much weight transfer

[Razer]

Actually, it's about ten more things to play with other than springs to fix this...:)

I had the same problems at my local track, where it lifted the inner rear wheel in a hairpin combo, and didn't carry enough speed. I just put the shocks in the outer hole on the arms, and the car felt stiffer, rotated better, carried more speed, and all this withouth bouncing around after a jump due to a way too stiff spring.

[steveproracing]

Agreed Martin I was being very simplistic! I was wanting to make the point that geared vs ball diff was probably not the first thing to blame! It certainly isn't to do with poor car design as some are trying to say! I appoligise for being a little sarcastic!

I didn't read your post too well either, missing the diff mention:thumbsup:

[ronny191]

hey guys,

last sunday tested my geardiff for the first time (see post on page 3)

nothing wierd or anything, diff did its job just fine, the difference between the balldiff are hard to spot for me, so cant comment on that.

i did have some altered handling in the car as follows:

when going trough a fast sweeper or fast 60 degree corner and i let go of the gass, the car spins out in midcorner not using any throttle.

when i let go of the gas a little earlier and drive my line right and can stay a little on-throttle trough the corner it doesnt spin out.

i didnt had this the weekend before. the only things i chanced were the install of the geardiff and i went from 4 degree toe-in to 3 degree.

any suggenstions?

oh im driving rearmotor on astroturf, surface was damp. just the same as the weekend before.
running spikes at the back, and cut staggers in front.

[steveproracing]

The looseness off power sounds like a lack of side bite. This is probably caused by reducing your toe in. Im not saying the diff had no involvement. But the toe in would definitely contribute to the issue u describe!
Out of curiosity what diff oil were u running?

[s22jgs]

Generally the car is very good. There is however one point of design which someone is currently making me a part to alter. once tested i will let u know.

If it proves not to be, then i will retract my poor design comment. it is however something similar in design to a part of the dex210, which also has exactly the same handling issue.

Hopefully testing at taplow on Friday so dont have to wait long to find out if i go back on my comment or not.

and just to cover my hiney, i am a total losi fan boy, so im not merely picking holes. i receive help of many people, and as such if this proves a transformation i will happily share it to all fellow 22 owners.

1500wt

i will change the toe in back to 4 degrees then, and see if your right:D

also want to chang the diff oil just for testing to see the difference.

not sure if i should go thinner or thicker?

[jaywestwood]

Thinner oil to make less friction will always be better as will rotate through corners better.. in warmer weather you may need to up it as will get warmer...

[ronny191]

whats the downside of going too thin?

something like 500wt for example?

aside from the chance of reduced accelaration..

[Razer]

whats the downside of going too thin?

aside from the chance of reduced accelaration.. It will be easier for it to unload all the power to one wheel while cornering, so you have to wait 'til the car is done rolling and turning before you can punch the throttle, there is also a bigger chance that the diff will leak...

[TKG26]

I just built it, can't wait to try it next week!!!

You did pretty good with that diff wed nite. :) First place not to bad LOL I loved the thing.. no more barking.. :)

[rcjunky]

pffft, my car has never barked since the day I got my car:p theres way too many sc10 gear diff haters, but now that the losi one is out I'm sure it will be more common. Has anyone compared the 2 diffs, like how they feel with the same oil? I had my sc10 diff with 7k and JAUNE's with 5k side by side and mine felt a bit thicker, but not much, so has anyone tried with the same oil?

[TKG26]

his was not 5k. mine has 5k in it

[Jaune]

TKG is correct, I used 3000. I should have a mix of 3 and 7K next Wednesday.

I love this thing on carpet!

I've built mine per trl22 rtr manual page 37,theres an exploded view of gear diff.

Loaded with 3k diff oil and ready to go.
Liked the feeling on high grip carpet,very smooth.

Thanks for the post of the gear diff/ rtr manual.
I see the base setup uses 1000wt gear oil. Is this way to light?

[Jaune]

Are you willing to post your set up for your car ?

Sure, here's my latest one. http://pages.videotron.ca/jaunerc/JG-22-dec-2011.pdf

I will try the trailling spindle again this week as well as stiffer diff oil.

[Fred79]

It's to light... try 3-4000k, that should do it for you

[cryer-evo]

so then i have had a look at the diff diagram and i have built it right it just seams very tight ? any one els had this ?

[ravens]

maybe you have filled with to much oil.it should be filled till gear shafts.

[Jaune]

mine felt tight at the beginning. I took it appart and use lighter oil (shock oil) on the outdrive shaft and rebuilt it. It was better. Is it stiff in your hands or in the tranny? I heard that some had binding issues (very minor) when tightening the tranny case.

[cryer-evo]

I will tack it apart and greas up the out drives as I think it might be the o ring binding on them thanks for your help

[Razer]

Is it stiff in your hands or in the tranny?

Sometimes, this forum contains some seriously disturbing stuff... :woot:

[Jaune]

Lol Good one.

[haris]

... in the tranny? I heard that some had binding issues (very minor) when tightening the tranny case.

I'm having some minor issue of binding when tightening the gears case, any advise or idea on why this is happening?

[Jaune]

Didnt happened to me but could you check if its rubing or simply too wide. I would try not to overtigth the casing for a while...

Razer, thats the less disturbing I could do. LOL:D

[Bob_Zahn]

I picked up the Losi gear differential last night. I also experienced binding when bolting the transmission case. I loosened the screws that don't attach to the motor plate and it was better. It's still tight but I didnt notice any issues on the track.

I also picked up the RTR shock caps and I'm thrilled with how easy they are to build with the bleeder screws. TQ and win last night to top it off.

[haris]

indeed, loosening some screws did the trick, thnx

[cryer-evo]

Last friday tyred my gear diff out on carpet with 3000w oil in it made the car so much better to drive so much so I won all of my races

[Jaune]

Good Job cryer-evo! I wanted to give another chance to my TQRacing/TeamC/Ansmann mid motor car but the 22 is now so good that I won't look back. I have a smile in my face everytime I hear others diffs barking.

[TKG26]

LOL we aint afraid to crank the slipper!!

[blade]

Tried the geared diff on friday in my 22 and found it to work very well on the astro track i race on.Also i run mid motor and the back end is alot more stable and have a lot of rear grip,if any thing its pushs the front end a bit.I am going to try a few things and see how it goes but i am very happy with it.

[haris]

tried it with 1000 oil on loose dirt and works like a charm, bye bye ball diff (at last)

[TKG26]

4 races now and the thing is still solid..

One thing though the outdrives are starting to show wear.. but nothing ill get to excited about...

I LOVE IT!

[Frecklychimp]

Ran mine for first time last night with 3K oil as a starter.... WOW! :wub

I was a complete sceptic about the theory behind it being an improvement, as a motorsport engineer...opinion was geared diffs are for 4WD cars and RTR toys... a ball diff design seemed more suited for 2WD... I was very wrong!

car was run mid motored on mixed grip carpet track with wooden obstacles at A1 Racing Club UK

Completely transformed the car, halved the steering aggression to a very smooth and stable feel on turn in, created the much needed rear end stability and grip mid corner and the launch out of corners is awesome.

Was a fair back to back test with nothing changed but the diff (admittedly in a spare gearbox so it can be dropped in and out quicker if needed between races)

It did take a couple of runs to get slipper set, had to turn down esc punch setting and brakes as i normally run everything max and use thumbs more carefully and took a fair few laps to get used to the new handling characteristics... does feel different on long big air jumps (doesn't respond as quick to throttle/brake adjustments for landing)

Was happy with set up of car before at same venue but it still felt nervous mid corner as on most tracks, so very happy with the new diff... it will certainly be staying fitted but will be testing thicker oils to see what happens.

Just hope its as strong as the rest of the car now!

Has anyone else tried thicker oils yet?

:thumbsup:

[NTS]

I have the Losi gear diff that I built with black grease on the outdrives and 2000cst oil. It feels to have quite a heavy action and you can feel the gear teeth as you spin it over, it's not super smooth. The o-rings seemed tight when I was building it and it is still tight after the first weeks running. Does anyone have any tips?

Maybe I'm expecting too much as I'm comparing it to the gear diff in my xray touring car that is silky smooth.

As an aside it was also a little tight in the transmission but that was easily fixed by backing off the screws a fraction so that isn't the problem.

[Buggy Driver]

Does anyone know the oil weight the gear diffs come filled with?

[Maddy]

What oil is best suited for the gear diff on high bite astro.
Cheers
Dave

[atsang]

hi guys, we have a loada people running 22's at our local club and again diffs were one of the first things to go in these cars... one fella tryed a sc10 diff and ended up wreckin his whole gear box so that was a no no from our point of view... we ended up ordering the individual parts to build our own diffs... a bit more expensive but we didnt care... although from what ive heard recently is the out drives are currently out of stock everywhere but thats how weve been the good old geard diffs... far better on astro... just seems to be smoother out of the corners...

[atsang]

as for oil weights and tight o rings i oiled the o rings up a lot... i didnt the first time i built it but then took it apart and rebuilt it oiling up the o rings and as to oil weights either 1000 or 2000 weight oils... the main oil being 2000 in our club but some prefer the 1000

[Frecklychimp]

Does anyone know the oil weight the gear diffs come filled with?

The Diff unit bought separately comes unassembled so there is no oil in it.

I started off with 3k but on high grip tracks found it was twitchy when putting power down out of tight corners, went up to 5k and it is a lot more settled and accelerates and brakes like nothing else on the track, I had to turn brakes down a lot as it was just making the slipper squeal and locking back wheels up!

I used green shock slime on the outdrive o rings when building and had no issues when binding, but I also ran the diff in by putting one wheel on the ground and letting power through the loose wheel and alternating it starting with low power and building up.

Never looked back since fitting it, highly recommended and loads more rear end grip, even on frost covered astro, plus it dials out some of the excessive steering the 22 is plagued with.

[Darren Boyle]

The Diff unit bought separately comes unassembled so there is no oil in it.

The latest ones have all been coming supplied pre-assembled, early ones were indeed unbuilt though......

[Frecklychimp]

Cheers Darren, was going to order another as a spare so have been pre-warned!

Are they full of that nasty thick grease like the SCTE ones are as standard?

First thing i'd do is rip it apart and check it over before fitting

I've just put a pre-built diff in mine. It did comes with a little oil in it already, but not enough for my liking, so stripped and re-filled mine with 80wt shock oil :D Sounds a bit thin I know but its all I had !! and anyway only feels a wee bit thinner than the stock oil, which must be around 1000wt ....

First run tonight on polish and carpet at Caldicot ... can't wait !!

[millzy]

Interested in seeing how that runs

[jaythewarrior]

so does the sc10 geared diff fit straight in?

[mrspeedy]

Update on friday nights run ....

TBH, the difference from the ball diff felt quite subtle to me, with the light diff oil the car was more manoeuvrable on the tight track we had than the ball diff was, but I was hoping for better traction/drive/braking really so am going to try uping the diff oil to 1000wt and see how that goes ...

Gear diff on carpet we are running between 3000 and 10000 wt. lower wt for tracks with lower bite and thicker for high bite

[mrspeedy]

Cool :thumbsup: buts its not the carpet I'm having problems with. We usually have around 25% polished floor so setup is always a compromise between the two. I'm hoping by increasing the oil to 1000wt it will give me better drive on the polish and have less steering bite on the carpet ...

... anyone tried this sort of surface with a gear diff ?

The sc10 diff has 1 more tooth and from our local club knowledge it wrecks gearboxes... well it has to 2 of our members...

One of our local racers dropped the SC gear diff and has never had an issue. He did break the thing in for a while i think before he raced it..

[zleader]

I am running the ae sc diff.. Never has a issue.. did not have to shim.. Just dropped it and ran it. No issues.. Its been about 6 months now..

I was going to buy the RTR diff but changed my mind.. Why it works great..

[Colin Kirkham]

Hi,Has anyone run a gear diff on a grass track ? If so what wt oil did you find works best ? Motor were you running, and in mid or rear set-up?
