ILIED 316 Posted May 6, 2013 I've got my nine inch apart at the moment. My carrier is away at the moment, so I've got a spool to put in for a bit. I cant remember when I last did mine. I think I had to set it to .020" backlash. Cant remember how to set the preload on the side bearings. I dont have to touch the pinion. So how do you do it?

gerg 10,871 Posted May 6, 2013 0.020" sounds about right, if a bit loose. I'd go 0.010" - 0.015", depending on whether the gears are new or old. You should check your tooth contact patch too, a bit of cheap spray paint will suffice. Preload also depends on whether you're re-using your carrier bearings or not. I say load up the carrier bit by bit till you feel some turning resistance, and a bit more if your bearings are new, to allow for bed-in. I've done a few Borgies this way and all worked fine. This is all of course if you don't have the actual specs handy. To actually set up your preload, get your backlash and tooth contact right, then in equal amounts, wind the adjusters in gradually toward each other till you get the right resistance in the bearings.

ILIED 316 Posted May 6, 2013 New bearings, old gears. The good thing about not touching the pinion is the contact patch should be still the same with the coreect backlash. I grab some bearing blue to check tho.Cheers Share this post Link to post Share on other sites

ILIED 316 Posted May 12, 2013 Yeah, I spent ages getting the broken parts out, but I think it was tungsten, not steel. I run a big fuckoff magnet on my engine sump. I think I'll take that advice and put a magnet in that plug in the diff when I get my wavetrac back 1 noddy reacted to this Share this post Link to post Share on other sites
