Durango's gear box for b44! :thumbsup:

Oops, wrong thread, post moved.

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.

:thumbsup::thumbsup::thumbsup::thumbsup:
Many thanks! I have found my winter project.

Cheers!

I will help you in your project Gayo ;)

:thumbsup:

Olivier, while you're at it - can I order those custom parts from you? Please! :drool:

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.

need to clean the poor B44!!!

Back? I'm captured inside the "Diaper Nightmare 1" :lol:

One-way bearings? No front gear diff?

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.

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.

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

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

Olivier, post some pics of the process please!

:thumbsup:

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?

Hi SHY!

Doing this job with a Dremel will be your second nightmare :lol:

The Durango pinion and B44 drive shaft are made in hard steel material...

I will post some pics very soon ;)

Oliv'

Hey BigBrains!

The Dremel can cut through anything - like a warm knife through butter! :lol:

Don't tell me you don't have the Dremel Disease anymore??? :D

SHY, here are the mods you have to do with your Dremel :lol:

The drive shaft shortened:

Once assembled in the B44 diff case:

Nice job, but with that mod that B44 becomes ther truly luxury 4wd in terms of €

OK... I admit being SLIGHTLY over optimistic on that one... :blush:

Did you make an extra set for me? Yo tengo dinero... ;)

You only need 1x right? Comes in packs of 2?

http://www.team-durango.com/graphics...ww/310005t.jpg

No, you have to buy two of these to have two pinions :yawn:

Sorry for being so slow... but isn't it enough with 1 front and 1 rear?

(both goes to the centre shafts)

Don't they come in a pack of 2? (#TD310005)

nope

Thanks :lol:
SHY :thumbdown: :D

LOL!!! I obviously need glasses! :D:D:D

I'm soon 40... things are going the wrong way...

A pic of 1 would be better for dummies though :lol:

Cheers guys

im over 40 and struggle lol, does it a few times on the durango site, shows 2 and says 1

So after all this what is the result with performance?? BTW nice job! :thumbsup:

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:

What brand of oil do you use?

Do you still use the Mid44 chassis? Pics?

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:

Thx!

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

And even cooler dude! :thumbsup:

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:

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:

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

hi all, very intrested in this mod how is testing going with these?
also would it be possible for some one to put a complete list of parts that are needed for the mod please
cheers

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 :

Whats the chance of getting this set up in Missouri? I would love to try this.
