Another question. Thank you for all the help thus far. Assembling my gearbox. Replacing all the bearings. Stuck at the 2 main tapered differential bearings. Problem: Cannot remove the inner race with roller cage. 1 side has virtually no clearance the other some. Ground a cheap 3-arm puller to fit the side with some clearance. Low heat on the race. Outer race in place to prevent cage collapse. No luck. Havent attacked the opposite side yet. Question: There are 4 holes behind the inner race, appear to be oil feed holes. Do I have to disassemble the differential unit and drive the inner races out through those 4 holes? Is there a better way to remove the bearings that I am missing? Again, thank you. John.
