AllRacing 7075 aluminum gearboxes!

[Probo]

Is it stock diff pinion?

 

[Overkill]

Yes, you use the stock pinion gear.

 

[Slevin]

Pretty sweet! I’ll replace with these once /if needed...

 

[iceman2733]

How long did these take you to receive Overkill? I take it based on them selling on Aliexpress they ship from overseas?

 

[Billyjoe]

Overkill, what shims did you use in the Allracing gearboxes? just rear one or both?
I saw the pic the other day and was wondering...

I ordered it directly from the manufacturer in China, took around 3 days.

It only needed 1, the Tekno shim.

I'm currently talking with Tang to try and improve the bearing housing tolerances.

Dang are you saying 3 days to ship out or 3 days for you to receive the product?

Also about the tolerances are they enough out that people should hold off on ordering?

 

[Overkill]

3 days to receive the order. I had some up and down play in the diff bearing housing. He's sending me another set so we'll see how they look.

oh god... I got my two gearboxes yesterday, I did not opened the blister yet but reading this I will have to check them both asap.

Please let us know if yours also has tolerance issues, please

So, I did not begin with the build yet, I am just gathering the needed parts. I checked the gear boxes and the bearing seemed well fitted in the gear box with no play so far...
Overkill, did you notice the play before mounting it or when putting it under load?

That's great to hear. I noticed the play just from test fitting.

Have you gotten the newer diffs yet good sir? I am very interested, I am rebuilding my ET48 with the M2C wide chassis figure I might try and pick these up if the tolerance issues are fixed

Should be getting them this week.

 

[Overkill]

The bearing tolerances are perfect on this 2nd set, thanks All Racing! The diff bearing housings have zero play and the pinion bearings snap in good.

 

[iceman2733]

Thanks for the update @Overkill , glad to see they fixed the issues. Going to grab me a set soon. I am going to have to go with a 6s setup like yours soon just to move mine it is getting heavy lol

 

[Mongoose]

Man, these are awesome. Glad to know they work in the ET too.

So are you working for Tekno yet @Overkill lol? You seem to do a lot of R&D. You get pretty in depth with it and understand tolerancing, proper assembly procedures and seem to have a broad knowledge of what is commercially available. I don’t see this much on the forums. Are you an engineer?

 

[iceman2733]

@Overkill

How have the cases been holding up? Any issues? The added weight help tame the monster at all?

I would use the shorter Arrma driveshaft for the ET. Haha thanks, I just really enjoy building this stuff.

I just got them installed in my buggy, haven’t ran them yet.
