I need to gather some assistance on this unit if at all possible. This unit belongs to an elderly man in my church and he is attempting to fix the right rear tire or replace it if it needs it. No worries there. He contacted me as his son had been attempting to get the rim off and it is stuck and will not budge. I confirmed the "e-clip" has been removed and the axle shaft is clear. He mentioned trying penetrating oil a number of times throughout the week. They have tried hammer, sledges, and even trying to punch it from the back side with a pipe.
I know nothing about this tractor as the attached pic is the first time I have seen it. Per the B&S engine numbers, it is a 1991 unit +/- a year. I would assume this wheel has a key way that is stuck but I could be wrong.
With all that being said, I wanted to come here first before I went and looked at it for any ideas, experience, etc. to get this rim off. I am assuming it does not have a set screw on the key way. At this point, would "heat," as in heating the hub of the rim, be the best bet? I know axle seals would be in line at that point. Any help or suggestions would be provided.
Thank you for your time as it is appreciated.
