Threw a belt on my CubCadet riding mower. Instructions say to "remove
bolt on end of vertical shaft (impact gun required), lower and remove
clutch assembly from shaft, slide off drive pulley so belt can be
removed/installed".

I had to use a puller to remove the clutch assembly. It didn't simply
"slide" down off the 4" long engine shaft. Next is the pulley. 3.56"
diameter. I cannot get it to budge. The only place to attach a puller is
the nearest belt groove. Needless to say, I've already buggered that up.
No access to the far side of the pulley.


Plan 1. Kroil. Warm it up a bit---just hot enough to be uncomfortable.
Spray on Kroil,
let it cool. Repeat at least 3 times. Usually you can sneak a couple of
"rolling head"
prybars in behind the pulley. I'm talking about the round prybars with a
long taper on one
end and a head that kind of looks like a toucan's beak on the other--sold in
sets of 4
cheap at HF. Try to pry it off. Try rocking it by prying alternately with
the bars. Try
putting tension on it and have someone whack the shaft with a deadblow
hammer.
If it doesn't work, go to plan 2.

Plan 2. Find a piece of pipe/tubing whatever that will fit over the shaft
and is a little
longer than the length of the exposed shaft. On one end cap it, or weld a
suitable nut on
it. You want to end up with a hollow tube, open on one end, with a pusher
bolt running
lengthwise through the center. Screw a short bolt into the hole in the end
of the
crankshaft so you don't bugger the threads when you push against it. Slip
the open end
of the puller tube over the crankshaft and weld it to the pulley hub. 3
good heavy tack welds
are enough. Screw in bolt to apply tension. Whack end of bolt with hammer,
apply gentle
heat, all of the normal puller techniques. The pulley WILL come off!
