Durango's gear box for b44! :thumbsup:

And how was this acheived? What parts modded? As the Durango is metric and the B44 imperial.

I'm also really interested in that mod :drool:

gear diff + metal gears = winner :woot:

The diff housings look very similar between the 2 cars. I would assume if it bolts to the car you could just swap the smaller cog on the CVA and pop the diff in there.

Metric/imperial doesn't really play much part in this. If you end up with 10 metric screws on your B44 it's not much of a problem.

The motor (V12--5.5) and ESC 120A.

After 4 weekend’s test in thetrack, the performance is Champion. No power lost. Gear noiseless. No problem.!!!!! :thumbsup::thumbsup:
The diff house of the Durango can be fit in my b44 gear box.
But the ball bearing is too small to fit in with the house(b44), and hard to fine the bearing here. So, I made a Alloy shim to fit the ball bearing to set in the diff house.

The small gear is from Durango also and which need to be cut and drilled a hole to fit cross pin (B44). That it’s.

Gayo

Shhh, don't disturb The Brain, he is actually making my parts :p

The only tricky thing is to mount Durango shaft pinions on B44 center shafts. You need a lathe and some skills for sure (thanks Oliv! :wub).

Otherwise, Durango diffs drop into B44 housings without any problems, they are of same dimensions as the AE stuff.

You need:
- 2 TD210001 (gear diff)
- 2 TD310005 (pinion)
- 2 ASC1731 (AE HD one-way bearings, as the Durango is metric)
- Some diff oil

Maybe also:
- 2 TD310022 (driveshaft boots :drool:)
- 1 TD310039 (rings holding the boots)

So that's around €150, without the lathe job. Ouch!
Hopefully I will have them for my next race on sunday. I will report how it feels here.

Good to see you back on the OR 10th scene.

One-way bearings? No front gear diff?

jimmy

07-12-2009, 10:21 AM

I think he means the bearings that support the oneway front diff, not the oneway bearings themselves. The oneway diff is metric - and comes with metric bearings with alloy collars to make them upto the size of the imperial diff bearings so it fits nicely inside the housings.

Gayo

Back? I'm captured inside the "Diaper Nightmare 1" :lol:
Oh, OK I understand now why you were so quiet since a few monthes :lol:
I have seen Diaper Nightmare 1 and 2, that's enough for me.

One-way bearings? No front gear diff?

No. The HD one-way, made by Yokomo for their TC cars, is metric. AE uses special ball bearings in order to use it on AE cars. You can use the same bearings to fit Durango diffs on AE housings.
Hope I'm clear :woot:

Edit - Jimmy said it better and faster than me

SHY

07-12-2009, 10:46 AM

Aha! That's great! So the only mod needed is on the center shafts then.

Olivier, post some pics of the process please!

:thumbsup:

SHY

08-12-2009, 11:17 AM

The small gear is from Durango also and which need to be cut and drilled a hole to fit cross pin (B44). That it’s.

So you don't need to use a lathe to do this? Just dremel off some material from the gear and drill a hole for the cross pin?

Oliv996

Gayo

22-12-2009, 10:11 AM

Well I had an indoor race last week end on carpet and slippy gym hall floor. Olivier gave me the modified bits on the morning so I could mount them between two rounds. Hey I have the best mate! :lol:

I filled them with 10K front and 3K rear. I thought that diff action would be quite slowed with such thick oils, but no, they felt like a slightly tight ball diff on front and a newly-built smooth ceramic ball diff on rear. :thumbsup:

You can still feel the hydraulic effect of oil by blipping the throttle while holding one wheel. To me (this is quite subjective though) the held wheel tries to spin harder than it would do with a ball diff.

On track, the tranny felt just fine, but that's a testimony to Olivier's awesome lathe skills. The car was very smooth and not louder by any means. I think that the louder pitch noise from Dex410s comes from the alloy chassis. Traction was very good. The car had a little to much rotation on tight corners, next time I will try with 15K-20K on front.

Is it hard to say if I was quicker with those mods as the race was on a temporary track. My home track is covered by snow by now :thumbdown: so I will have to wait until I can do more tests, but it feels good to know that I can tune diffs as much as I want, from a super-free spinning diff to an almost locked traction machine :woot: And I can use driveshaft boots, yummy! :drool:

SHY

22-12-2009, 10:33 AM

What brand of oil do you use?

Do you still use the Mid44 chassis? Pics?

Gayo

22-12-2009, 11:01 AM

I used AE oils, but I have some Losi bottles too. I don't know if they have vastly diffreent thicknesses, but it should be close enough for me.
I will post pics later.

Since I use lipos, I run a standard B44, with Losi shocks and now Durango diffs (obviously!).

I am thinking about coming back to the MiD44 '08 chassis though, with brass weights under lipos. That car was really good, easy to drive, quite fast and rather unique.:drool:

SHY

22-12-2009, 11:07 AM

Thx!

Why not go for an Atomized B44? AFAIK it' the same weight distribution as the MiD44?

And even cooler dude! :thumbsup:

Gayo

22-12-2009, 11:26 AM

I think that the motor is even more on the front on the Atomized?

Cool car for sure but I'm afraid I don't have fossil fuel under my garden :cry::lol:

SHY

22-12-2009, 12:12 PM

As on the MiD the middle shafts have swapped positions, so it should be the same I think...

And that carbon tub is übersexy!!! :thumbsup:

22-12-2009, 09:38 PM

Yeah but the slipper is also reversed on the Atomized B44... Come on SHY...:blush: you should know that, you have both cars...

The mod works really well, I find my B44 easier to drive, less twitchy on the slippery stuff as well as on carpet, and I even have better traction.

I put a list of parts used on post #11. OK, here it is :D :

I bought mine on Tower Hobbies, it seems that they are not available anymore. Google is your friend here :)

It is basically a B44 diff bearing with some kind of thin sleeve on the inside so it can mate with the metric one-way.

SLEENAD

06-04-2011, 06:00 PM

what are the dimensions of the bearings needed???

inner dia / outer dia / width ???

is it a mix between metric and imperial???

Just take a bearing with correct width and too big inner dia and to small outer dia, then take some stainless and produce matching rings tight shrinkfit!

I promise you it will work! Your bearings will not last as long due to the fact they're smaller, but I guess that's a minor point.

F-1

06-04-2011, 06:14 PM

Bearings: 10mm inner d., 5/8 inch outer d.

West Ridge Racing

06-04-2011, 06:34 PM

So it just looked around the old sparesbox I got when I bougt an used B44 and in that box I found two oneway diffs that got blue anodized on it and those bearings had a bigger inner diameter than the standard ones. Are those the correct ones? In that case I can congratulate myself om my lycky day:thumbsup: I have got six bearings then.
Inner:10mm outer:15.88mm W: 4mm

Now my converted B44.1 will get geardiffs too. Think if those bearings will eventually wear out I can replace the with 10x16x4mm bearings. Those are a lot more easy to get a hold of. some careful dremel work perhaps but think it will work.

Got everything a need now but I wonder how to remove the axle from the bevelgear. Heating it up maybe and cool the axle?

corallytje

06-05-2011, 05:12 AM

I think the bevelgear and the axel are made from 1 piece. So, the solution is to cut the axel off.

That is not a problem, the problem is how do you make the hole in het bevelgear for the pin. How did you manage to do that?

corallytje

08-05-2011, 08:49 AM

:woot:I've done it. It wasn't easy to do, especially the bevel gear.
Still need to do the front one.

Bugle

14-07-2012, 03:25 AM

Yeah interesting how the B44 is quieter than a Durango with the same gears. Quieter and smoother than plastic gears it seems.

I looked at using the thunder tiger sparrowhawk diffs but it looked like it was more work?
Still have the problem of metric bearings, B44 dog bone ends didn't fit into the Thunder Tiger drive cups. Then with the pinion already made to fit onto a 5mm shaft putting it on an undersized 4.76mm B44 pinion shaft wouldn't work so it seemed like there was more custom machining to do there than with the 410 pinion.
The diff centre also only has 2 spider gears in it vs DEX410 with 4 gears so it might not hold as much power.
