Cleaned up and painted the 1998 T-100 rear drums today. Also did a quick test fer the bolt size...I pulled the battery tie down bolt and tried that. Presto! It's the right size and thread pitch. I'm guessing it's a M10x1.5? I'm headed to the hardware store and gonna see what fits in the threads up front. I'm thinking I'll need a good length fer the bolt...maybe about 3" or so?
Er...wait a minute...I noticed that there was a centering hole in the middle of the axle hub. I'm sure those threads can be used to wiggle the drum out but from what I'm familiar with "pulling" something out would be to bolt a puller into the bolt holes and then using the center bolt to pull the drum off!
So a standard puller should do...something like
this $10 puller set...
