I have a M15A with a Timken 53625 full floating spiral bevel drive. When I bought it the rear pinion bearing was shot and there was no oil in the case. The axle case bolts were loose. I replaced the pinion bearing to get it on the road knowing that the pinion/ring pattern was not correct. The pattern is too high on the tooth and requires moving the pinion closer to the ring gear (move pinion in or back). I now have it fully dissembled and have found that one of the differential case side roller bearings is galled. I have replacement bearings for that. I plan to add a shim under the pinion gear to space into the axle case.
I have noticed that the differential (spider gears/side gears) have considerable slop in them. There is no specification for this so I don't know what is acceptable. I would like this thing to be tight so I added a shim made from 0.012 sheet metal behind the differential side gears/thrust washers. Has anyone done this? Is this an acceptable method to compensate for wear of the differential?
Here is what the differential looks like:http://studem15a-20.blogspot.com/201...1_archive.html
