I have put the final drive inboard shafts into the freezer. The bearings go on right to the point where you have to put the circlip on, but no further.

Might need a press? Designed to be a tight fit I think......

Cannot go any further. Hits the end. Just enough room for the bearing and circlip. I put the shafts in the freezer, put the bearings in the oven at 200.

Almost got it on. But had nothing the diameter of the inner race and enough depth to bang it down. Went on about 1/4 of an inch.

If the shaft is to the correct tolerance and the bearing from a reputable brand to the correct tolerance then you should be able to press the bearing on with it and the shaft at ambient temperatures. Easier if the shaft cooled and bearing heated but still possible if not.

Ideally you have a suitable length of pipe to bear on the inner race of the bearing and a press. A suitable bearing splitter and puller from the other side is also an option. A hammer or a large vice on a length of pipe is also possible. A suitable rod of about 1/4 inch diameter or flat end punch can be used also to drive the inner race on by carefully tapping around the periphery of the inner race.

What ever method you choose always support the shaft in the centre to avoid bending the arms
