I have an old sickle bar mower that came with my recently purchased 1967 Simplicity 2010 tractor.
The sickle bar mower is seized up and the drive shaft will not turn. I managed to pull out the drive shaft and want to replace the needle bearings but I have no idea how to remove them.
This is an original Simplicity sickle bar mower and I believe it is the Simplicity 990465 - 46" Sickle Bar. It seems to match the diagrams I found on Parts Tree and the bearings in question are 2154258SM. They appear to possibly just press in but I do not know for certain. Anyone familiar with these?

I also have the 42" mower deck and 36" snow blower that appear to be original Simplicity as well as a dirt plow of unknown origin and a snow plow that I believe is Allis Chalmers. It was a nice find though it did cost me a fair amount but it is in great shape and all repairs are minor for a good running tractor with electric start and the hydrolift all in good working order. Even has a new generator/starter. :)

The bearings in question are actually up at the top edge of your image though it is the same part number, just in a different location.
I assume there is a gap on the inside of the tube that I can use a screwdriver or chisel to get behind the bearing and tap it out? Or do I need to find something I can press the bearing out with? I have never removed bearings like these and not quite sure how they come out. I do not yet have the new bearings in hand to give me any clues either.
I figured it will be easy but thought I would ask first in case there was some unknown issue I am not yet familiar with. I do not know if the bearings just sit partway into a tube that is a uniform inner diameter all the way through or if there is a wider recess into it on both ends where the bearings go requiring a different approach to pulling them out.

Thanks for the help.

Sounds like a real nice package! The bearings should just knock right out, then you can tap the new ones in, grease things up and be on your way.
