Source for diff rebuild kits

#1

I need to rebuild the diff on the blue car and can’t find where to source these now. Can someone point me in the right direction? Thanks

#2

When I shut down Factory 3, I turned over my suppliers and details to David Harrison, at http://www.harrisonmotorsports.com/

I believe he is sourcing the parts. The only thing that’s hard to find is the discs themselves; the seals and gaskets are easily found.

The link to the how-to is here https://docs.google.com/file/d/0BzfkUgART_B4OTgzMWMyNTgtNTYyZC00ZDA3LTkxODItNmY5MGE5ZWM0ZDhj/edit?authkey=CNS-1ssO&pli=1

Travis, Bimmerworld or Zygmunt (ask for Chris) should have them.

Thanks guys! Ordered seals and gaskets from pelican and the discs from Bimmerworld. Around $185 to the door for a disc and seal replacement.

Is there a DIY on replacing the bearings… all of them?

Sorry to not have posted sooner but IMHO the 188 diff plates from Bimmerworld are very overpriced.

For future reference, what is a more acceptable price and where can they be found for that?

… checking my previous sources, will report back…

I am interested, too. I haven’t had a chance to look, but my diff is covered in fluid. I think I blew the front seal towards the end of the race Sunday…

Guys, I’ll have 4 friction discs & 4 four tab plates with me at Nationals. I got them to rebuild my own diff and a spare diff but if someone needs the parts I can get more. $50 for a friction disk, $20 for 4 tab plate.

As a note to the above instructions, If I may make/suggest a correction.

Step 12:

These are actually 8mm X 1.00 socket head screws, grade 10.9. Since these are almost identical to clutch pressure plate bolts (8mmX1.25-10.9), we torque them as such at 25ft-lbs. Suggest using ‘blue’ lock-tite.

I also suggest taping the bolt holes to clean out any crap and previous lock-tite. If you plan on rebuilding your diff and need this tap, order it online ahead of time. 8mm X 1.00 is NOT a standard metric tap size and you will find yourself driving all around town in vain. Trust me, I know. :wink:
