Well, seems like I posted while back to one of your other threads on how to replace the lower crank pulley... It needs to be pressed back on like it was originally. I read too many horror stories in the achieves about honing out pulley and drilling and taping for set-screw. Also beating it back on, broken pulleys damaged thrust bearing, and last but not least broken and or damaged crankshaft.

I'll try to take a picture tomorrow on how to press it on and give dimensions again of material needed.

1st. I used the boltster mounting holes(upper
left and lower right)on front of engine.

Jerry it must be put on within a minute of coming out of oven or it will cool enough to shrink back to original size. The same thing happened to me on the first one I installed. I pulled it back off and heated it again, The second time it went right on. The secret is getting it from oven to tractor before cooling off any. Good Luck.

If you look at the block where the front end bolts on, you will see 2 bolt holes that are on each side of the pulley. Use 2 long (redi rods) bolts with a bar of iron across the pulley & pull it on. Or you can do as Janickolson suggests.

Pull it off again with what is probably a fresh made puller. and try this:
Use a fat dowel and split it with a saw for 3" down from one end. Place 250 grit silicon carbide paper ripped to 2" strip into the slot and wrap them till they are just right to fit the hole in the pulley.
Driving it with a metal lathe, or putting a cutoff lag bolt in the end to drive it with a drill press or 1/2" drill, use it to enlarge (full length back and forth for a while) the bore of the pulley so that with some engine oil on it, it will just go on with light driving force while cold. Drill and tap for a setscrew into the key. This makes it nice for later removal as well. JimN
