Been trying to remember this morning what I did in the past, if memory serves... bearing were heated and dropped on the crank, flywheel side case was then heated and assembled crank dropped in(pretty sure there is a lip there) then PTO side case heated and dropped on and bolted up. everything seemed to sort itself out, crank was centered etc. etc.

No lip on either case half on this 266

I have a steel plate that I clamp in the vice.......then I slide the crank on it with the steel plate in between the counterweights. So that the stub is sticking straight up in the air. That supports the crank so it can't get knocked outta wack....

Then I drive the bearing on using a piece of pipe that fits on the inner race. (on bearings with steel cages I heat a plate of steel and lay the bearing on it to get hot) No chance of damaging the crank or the bearing this way. Once both bearings are seated on the crank, I heat the case half and slide in the crank. Some saws use the oil pump as a positive stop, others bottom out on the flywheel side bearing pocket.

So in this case, on the 266, I should seat the bearings on the crank first?
I usually heat the bearings in a small pan of motor oil on the grill if I go this route .... ;)

The manual says bearings in case first......then pull the crank in with the proper tool.
