Differential case with damaged components.

homemade sleeve puller. Locking rings are threaded onto this sleeve and gear cluster/bull gear bearings race in these two sleeves. Sleeves are held in case by large airings. A rubber hammer may have been able to do the job but the sleeve puller was more precise. I reused my airings on the entire rebuild without any leaks. Prongs are designed to be reused.

Prongs and airings are O-RINGS

Never on solid pavement other than the several times of year I plowed the paved culdesac.
This tractor was bought in 2002 .I believe the brass Bellville washers separating the worn axle drive gears from the differential housing were never installed at the factory. The other 2 brass Bellville washers in the differential were fine and reusable ,(shown in pictures). As was the brass pinion washer. -
Ps,Because those brass washers were not installed at the factory it took 1200 hours for those case hardened steel gears to wear their seats into the relatively soft cast iron differential housing. That original looseness plus the subsequent increase in gear lash / mesh of the other gears involved and they began failing.

I ended up buying a new center gear case. I must have not stated that him my rebuild….. sorry. Cannot remember the price from Affordable.
Have used the 4wheel drive many times since the rebuild but use it only when necessary. Before rebuild it was engaged 24/7.
But any 4wheel drive system should be bulletproof if manufactured correctly. I feel those perceived missing brass Bellville washers weakened the system. -
yes things in china are hit and miss as far as are all the parts in there, I bought a mower for my skid steer , it is a great bear brand , it was sold as having a problem so I got it cheap. so I powered it up and there was quite a grinding noise , it is full of oil . I removed the gear case and opened it up the drive gears bearly touched , so I bought a new gear case , which is a good one, still came out good price wise. but the original gear case should have never been let out of the factory and they would not eat the defect , I had to pay for it although they did give me free 3 day shipping from china.

Update 7/26/22 ,So far my rebuilt front differential is working perfectly. Have added 200 hours to that rebuild by moving dirt 800 feet to fill 1000 tires in a tire retaining wall. Will try to upload a picture. CTOA would have a better website if the administrators of the site would increase the file uploads.

I see the retaining wall, that must be quite a bit of hand work filling and packing the sidewalls , I do not know why but I was wondering is there anywhere in the US (california) where they (the govt) are going after people for using what they call has. mat. in buried appilications? I see people using them for house construction , that must be a real pain to get the thermo mass they are looking for.
