losi diff rings?

[captainlip]

next month im rebuilding the diffs with 12.5k and 7k ultimate diff oils,

need some diff seals and aparently losi ones are the best, but I forgot the part number and cant find it on je spares.

[slowjun]

My bad...

A3505, or at least that's what someone posted a few weeks back.

[fastinfastout]

have not heard of the losi seals, I hear kyoshos are the way to go

You could also use these: http://www.tresrey.com/tresrey/products/tys246_eng.html

I think also some have been saying to use a thicker washer after the o-ring and before the e-clip as this can help keep the o-ring seated and stop the output cup from floating so much.

Use thicker washers 0.8mm, part no TD709001. Reduces outdrive wobble, end float which opens up the seal causing excess leakage. I use the standard seals and only need to slightly top the diffs once every 4-6 weeks depending on how often I race. :)

With the thicker waahers the standard seals are fine.

Now for the moaners, the every seal leaks you can not stop them leaking it's trying to seal a rotating part!!!

An x-seal is the most efficient way of sealing a rotating part and if use an o-ring it has a larger contact area causing friction and a tighter diff.

Yes use them in 8th nitro because they use thicker oil so friction has a minimal effect. But on the 410 it'll create a tighter diff action.

I'm sure in the years of development durango chose an x-ring for the above reasons. :p

You dont go fast enough Pack to spin the oil out :lol:

Kyosho p5 are the ones people use , have them in mine and no problems........ yet !

Where were you Andy on Sunday? I was fast enough to beat all the full fat Durangos, you would've been another notch on the bed post sonny.

I was fast enough, I hope I beat you at the next round. :p

[Holeshot]

Kyosho P5 - Part No: KYOORG05
Ive heard of people using Losi ones aswell without any problems.

[WHITTLER555]

Hmmm interesting? I re-built my diffs with the Losi O ring and raced all day Sunday with no hint of drag on the diffs or any oil leakage.

There seemed to be no detrimental effect at all?

There is no extra drag on the diffs as the gear and outdrive spun freely before I completed assembly.

I will use the car again this Sunday and if the diffs are not leaking I will consider the change a success.

Damo.

Well, I've decided not to be a sheep. I'm going to change my seals to HPI P5 o-rings. They seem cheaper than Kyosho and Losi seals. :thumbsup:

The part no is A020 apparently, I'll let you know the outcome. :confused:

I had interference otherwise it would've been a differnet story, I wasn't off the pace in qualifying.

Gone back to 40mhz. now so shouldn't have any issues. :thumbsup:

Mint :thumbsup:

[Andyp]

HaHa with cmgreen,

@ dpack you have only gone back to 40mhz while your 2.4ghz get serviced @ toys 'r' us !!!

Really tho, pack that is a good find if you have found hpi seals and they are the same. kyoshos are expensive and seemed to be getting a little hard to find a little while ago.

[captainlip]

bought the hpi ones for £3.40, kyosho ones at over £6 is a rip off

and the Losi ones are about £1:40 from MK Racing:D

[dpackster1980]

The HPI ones aren't described as silicone so they'll probably just be rubber. I think they'll be harder but should be more than upto the job as they are fitted in aload of HPI ic car diffs. :thumbsup:

If it works what a find, it's less than £2 for 4.

that includes postage! :thumbsup:

utter bollocks, loads of applications seal high pressure rotating parts hydralic pumps crack seals etc etc

You are wrong, I work for an excavator manufacturer and know what seals fit what applications they are suited to.

If the orings are so great why aren't they used as crank seals on engines, on output shafts on anything that rotates that especially exposed to the elements Mark? All these use spring loaded seals as they are better at keeping the crap out.

As for hydraulics, internals use orings and on the external casings on output shafts spring loaded seals are used.

Unfortunately it's not possible to make them that small otherwise they be perfect for the Durango.

The next best thing would be a slightly oversized standard seal with a deeper groove in it.

Mark you seem to think know better than everyone that's ever lived. Obviously you should a head designer of everything because manufactures of their own products are wrong. :woot:

[mikeyscott]

Fitted the p5 kyosho rings and feels much better. Time will tell.

Will prob order the washers too.

Just a case of what oils to put back in now..

[mikeyscott]

Would change the seals, but can't get the f'ing thing apart. Gear will not budge! Now where is my 511!!

Block of wood, hole slightly larger than the outdrive, old driver and a small hammer = diff in bits :lol:

You'll ruin the e-clip and washer but it's quick and doesn't damage the diff casing either. :)

im just challenging your claim that all seals on rotating parts leak!! the sentance of yours i high lighted in bold!

[captainlip]

everyone keeps telling me to get the losi or kyosho seals

i have some hpi p5 part# a020

is there any reason why i cant use these or a possibility that they would fail like the durango ones?

They'll fit, I'm running them.

They are not silicone so don't know if they'll eventually swell but I doubt they will because they are used on the HPI gear diff outdrives.

Cheaper and easier to find in stock than Kyosho ones! :thumbsup:
