[Farmall] 39 A: Crankshaft pulley with setscrew!

[Howard Weeks]

I bore a 3/8" hole on both sides of the center in the thin part of 
the pulley.  I then use a regular slotted bar type puller and a 
couple long bolts.  Haven't broken one yet.  I put them back on by 
bolting a 4x4 across the front of the engine (using the bolster bolt 
holes) and then push it on with a small 2 ton jack.  That always 
works for me.  I suppose there is some possibility of getting the 
pulley out of balance but, if so, I haven't noticed it.
