How does the belt drive pulley on a Poulan rear engine rider model WELRV1 come off?
The parts list shows a 1 piece pulley attached by a bolt in the usual way in the center of the crank end. This one seems
to have a one piece collar with 1/2 of a pulley on the end. The other half of the pulley is also the drive plate for a
friction disk. [This thing has a drive section just like a snowblower.]
There was no allen set screws in the collar part.
There were three bolts on the inside part of the pulley which screw into the other half, the drive plate part. I assumed
with the screws out the drive half would come off. It would not.
The drive half is fairly thick so I tried tapping from the back with a brass hammer but it would not budge.
I tried a couple of pickle forks and no movement. I heated it up and hammered in the pickle forks with stiff blows.
It still would not budge.
This thing has me puzzled. Since the collar does not have allen screws what holds it on? On the collar part of
the pulley there's an impression on the outside like for a key. But since it's on the outside there's nothing that
goes over that slot or could mate to it.
What's up with this pulley? How does it stay on and how does it come off? This machine if only a few years old and had been garaged so no rust and looks like new. The drive plate
looks funky but that's due to the heat applied. There's no rust on this machine and I don't think the pulley sections
are rust frozen.
[The engine is hosed and I'm taking it apart to see what happened. The cam went for some reason and in a
weird way. When the fly is turned to work the valves (Briggs 8.75hp OHV) the two valve rods move together. That is
they open the valves at the same time, then close them so no intake exhaust action. One valve also clicks with 1/16
inch jumps. I don't see how a messed up cam could work the valves like that so opening it up to see why? The
flywheel will only go in one direction but the rod seems fine moving the piston up and down at it should.
The engine had issues and I fixed those then took it for a test drive. It ran for about 15 minutes then stopped without
any noises and developed the valve issue. ??]
