28, I can't lift the weights and in the serial numbers on them it says 262 8R. One guess is that 262 might be the pounds. I also found a JD insignia on them, so I'll have to keep that part against the wheel so nobody catches on.
Here they are all painted up.
The second picture is the new seal installed, [wet]. That part went well, but from there on ---not so much. I pressed on the drum, [quite a tight fit] and the last little bit it would not go. For some reason I tried to turn the axle, and found it seized. Something was jamming the drum. Did I mention that the drum is a really tight fit, well it was horrible to get back off again. There were threaded 1/2" holes in the back of the drum to help pull it off, the first time I pulled it. The half inch bolts pulled the threads out of the holes, so I bored them out and retapped them to 9/16" and found some good solid 9/16" threaded rod. This time it pulled so hard, that I wrecked the 9/16" threads. I retapped it out to 5/8" and found some 5/8" long bolts with lots of thread. That and some heat pulled the drum off. See high up in the right side there is one long bolt holding on the bearing retainer. That had jammed into the drum. I had taken the nuts all off that retainer and then couldn't get the retainer out of there so I took the seal out with a screwdriver and a homemade seal puller. So I then put the nuts back on and tightened them. I think the factory guys put one long bolt in there and then just left the nut loose, not pulling the bolt through very far. So I tightened it up not thinking of the consequences, and paid the price. Anyhow, I got the bolt cut off. [can you think of what tool a common guy could reach in there with and cut off that bolt?]
