Thread: Replacing Salisbury bearings

I got the numbers (Timken 388A) that you've posted up previously here Salisbury shims

From memory, I think I ended up with one shim left over of the ones I removed from the old bearings. With the setup cones (both the borrowed ones and the new 388A's) all the original shims were required to get the preload correct, but it was too tight with the proper cones fitted and I had to remove a shim from the total.

Seems like the new cones I had were just a fraction wider than they should have been. Maybe I ended up with 2 of them at the high end of the production tolerances - don't know. Can't recall if I actually measured the thickness compared to the setup cones, as by then I was completely over the job

Have done quite a few diffs on race cars many, many years ago but it's been a long time between drinks (and never really enjoyed it either) but I've seen too many diffs cocked up by experienced diff builders too. I just can't farm this sort of job out, just goes against my nature.

Always used dummy bearings for setup and never had a problem, not sure what was going on there Steve ?

Hope it goes smoothly too, life's interesting enough ATM without inducing further complications....
My the hell do we do this to ourselves ?

BTW, there's no noises, etc, but I'm swapping in a new centre and at 310,000km I'm just worried I'll be asking for trouble not doing the pinion bearings and seal too......
