Here's one for the guru's here. I'm no gearbox specialist, in fact I hate working on them. I usually stick to engines and making stuff
So.... anyways
Pulled a Transfer case out of a 91 Vitara today to put a bearing kit through it.
Apparently the owner had reduction gears fitted about 12 months ago, but the mechanic who did it never replaced any bearings .
Now, I've Found all sorts of wrong.
Nice silvery oil. which I was sorta expecting as the customer had complained of play in the output shaft
Now, the first thing that struck me as odd, a 26mm welsh plug floating around inside the transfer case itself.
As I've pulled it down, I've found the the thrust washers against the gear set on the lay shaft have been spinning, maybe 3-4mm off the end casing is gone
The worst part is the ends of the gear set are now brinneled due to the flogged out thrust washers.
My question,
I know the gear sets are hardened, but could I get the ends lapped/machined smooth and shim it up against the new thrust washers ? (assuming I can get new thrust washers)
Or do I need to tell the guy he's up for a new gear set?
The teeth on the gears themselves are in great nick
