Borgy Diff Centre Backlash Adjustment

[NinjaMekanik]

Hey Guys,

 

I am going to lock the diff on my ke55 via welding the diff centre. I got a spare matched diff centre and pinion. My question is, how important is it that the specific pinion and crown wheel stay together and how do you adjust the gears together if I'm going to use a different centre with the existing pinion?

 

Havent pulled it apart yet just wanted a bit of an idea before i did it. any help would be apreciated.

You have to use same cw+p or get the 2 you want to use lapped.

You may also need to shim the diff so that they mesh correctly. Most manuals will have details about doing this. It involves some marking blue and a bit of messing around. Personally I'd keep the whole assembly together including the housing to save a lot of messing around.

Ok cool. I had a look at it last night and there is already heaps of backlash so i thimk either way i should sort it out.

I'm familiar with marking blue and getting a good pattern just never played with a salisbury type diff so I'm not sure how to adjust

Its all in the shims in a 55 borgy unfortunately. Maybe try rearranging them and see if you can't get it any better. Otherwise if its been apart before maybe the shims weren't put back in their correct sides.

hmmm ok. mayb i can buy the shims at a driveline place

Be prepared for some digging. I remember needing some trying to rebuild an old Datsun gearbox. I ended up making my own. If you can work out a way to measure the size you may even need to start talking to some engineering shops.

 

Good luck! :)
