Hey gang,

Need a little help, with the above mentioned diff. I am tearing my MIP gearbox down, to do a little maintenance on it, and now that I am to the diff, I cannot for the life of me, figure out how to get it (the diff) apart.

I see that there is a small grub screw on the side of the diff that is threaded, and I can back it out all the way, but I still can not figure out how to get the rest of it apart.

Any help would be greatly appreciated.

Check out the parts list in the scans section;

Basically it's held together in three parts.

First send an allen key down the hollow output adaptor SP-16 into B-3 which has a bolt which attaches it to SP-17, this hole allows diff. adjustment. Unscrew this all the way, the bolt won't fall out but you will be able to dettach SP-17.

The diff. should then come apart into three parts/assemblies. One just a shaft side SP-17, secondly the gear B-3 and then the shaft side assembly comprising of mainly SP-16 and B-6.

This should then reveal three very short allen head bolts in B-6, undo all of these, pull it apart and it is disassembled...

I'll try and find you the MIP 4wd scans in the scan section which show what I mean...

edit: they seem to be missing in action or not posted. Anyone know the ones I mean, on blue paper? I can scan them if needed...

BTW I have added the part numbers corresponding with that scan and be aware I have not mentioned the thrust washers and ball bearings. Do not loose these and make a note of the order they come out.

be SUPER careful unscrewing that diff screw.. i snapped on and it broke at the other diff half so i couldn't get it out once

Yeah when re-doing these diff.s I don't bother pinching the diff. adjustment bolt to bend it as I am not running mine.

Oh and Erich there is always time for some lube...

Thanks man.. i rather prefer "Slick chops"

on a side note how creepy is it seeing that guy staring at me and Mike Reedy

Thanks fellas......I thought maybe I was just completely missing something blatantly obvious, and as Ed pointed out, I did! Actually, my problem was, that I was trying to use my Losi hex drivers to back out the diff bolt, but the shaft of the tool was too thick to let the end fit down far enough to grab the head.

I have to second the recomend to be careful with the center screw. Generally when you assemble them, you bend the center screw to keep it from loosening. This makes them very susceptable to breaking

No problem mate, I built up a new one this weekend too. Woot!
