Savage Diffs

[Jahay]

I had this prob with one of my cases too... and when i screwed it up tight and my mesh didnt allow the gears to turn....

hmmm i found that my HD Diffs (original diffs in flux) worked very well and were smooth... when i put my BP diffs in teh GH Bulk.. there was a lot of friction. Many i know who use GH Bulks with brushless systems say it is unnecessary to use BP Diffs as the mesh is always constant anyway.... and i some what agree... but i wanted to use my BP ones which i paid more than $50 for haha

I didnt think i had a prob with my bulk but the mesh was definitely too tight... i attached my drill to the end of the pinion after tightening the bulk up with the shock tower in there) and the gears then used my drill to turn the pinion and spur for a good 5 minutes, the mesh had bed it self in. Now my diff turns extremely smoothly...

OK guys I figured out my problem with the BP diff not fitting in the GH bulk.

I was using some honkin' 6x15x.2mm shims to shim between the bearings and the outdrives. The bearings sit very squarely and snug up against a little wall in the alloy bulks, and when I would go to close the bulk cases there was no room for a 15mm O.D. shim beside them, so they would protrude and make it so the case would not close all the way.

Lucky me, I brought home a file and an oil stone today from work, just for this job. Well I did not use them on the aluminum bulkhead like I figured i would. I ended up filing down the 15mm O.D. shim to match the O.D. of the outdrive so it wouldn't interfere with the bulkhead. Problem solved! (Yes, i filed down a shim )

Now I have a new problem.. I finally got a perfect shim set-up so the diff spins freely and there is just a hair of play between the pinion and the ring gear. To achieve this though, I now have NO shim between the bearing and the ring gear. As soon as i put a shim there, the pinion/ring are louder when spun and just overall dont sound right.

The bearing in use is a metal shielded Boca bearing and it is the beefier of the two (8x16x5mm) for what its worth.

Will this set-up work or is the bearing going to blow out? Is there a way to get the ring gear away from the pinion without removing this shim?

Thanks a lot guys!
