Hi:

I am fixing the main roller on this windrower/swather. I have the roller off the machine and now need to separate it from the drive pulley. Is this just a press fit? That is how do I get the bearing out of the roller to replace it?

Thanks

Assuming by pulley you mean chain sprocket, it probably has set screws (Allen wrench) that lock it in position but will very likely require a gear puller to pull it off the shaft. The bearing will be an eccentric lock collar type also with Allen set screws on the lock collar. You loosen those and then take a punch at an angle in one of the holes a drive it to rotate it and unlock it usually drive it the opposite direction the shaft rotates if installed properly. The bearing will also require a puller or often it is just easier to torch it off. A 4” grinder and cut off wheel might be able to perform this task as well but sometimes there isn’t enough room. You only need to cut about 2/3 the way through the inner race then set a large cold chisel in the groove you cut and whack it hard with a big hammer. This will crack it and then it will release to be pried off the shaft.
