Alright, I messed with it tonight again. I dont want to put heat on it as I will destroy the seals and bearings. The adjusters are frozen. They won't budge. I am going to have to drop a puller on the wheel while its installed on the bike with the hub nut removed. Has anyone done this? I don't know if the wheel can handle it, but I have pretty much no other choice right now. I can't beat on the castle nut and hub any more, its not budging. Its soaked in penetrating lube and has been all day. I've tried gently beating around the drum, but even gentle taps have put small marks on the drum, so I can't hit on it really hard enough to make much difference. I know dents on the outside don't translate to the inside, but I don't want to REALLY hit on it. If this was my truck where I could run down to Oreilly, it would have been off already with a torch and 5lb sledge...guaranteed.
I tried loosely putting the rim on the bike with the drum nut removed, and then just slamming the wheel towards me to the lug nuts, but its not enough force to pull the drum off. I feel like if I can put a puller on the rim and drum and put a little pressure on it, not CRANK it down, just firm it up, and tap the center bolt, it would give. Maybe not. I got no other ideas.
Any other advice for putting a puller on it?
