> Anyone know how to remove the crank shaft pulley on 9000
You need a 27mm socket ('90 and earlier model-years need a 30mm), and a
breaker bar, preferrably at least two feet long.
If you have a 5-speed manual (doubtful in a CD 4-door model), you can get
away with putting it in gear and having an assistant stand on the brakes
while you loosen (and later tighten) the crank pulley bolt.
If you have a 4-speed auto, you need to improvise a ring-gear blocking tool
that will fit through the timing inspection window in the tranny
bellhousing. This is needed to keep the crank from turning while you're
trying to turn the pulley bolt. You're lucky you have a '91, because from
'94 onwards there was no timing window, so the only way to block the ring
gear was to remove the starter and work through that hole (or butcher the
bellhousing by drilling holes in it).
Another way to loosen the pulley bolt is to set the breaker bar and socket
on it and crank the starter for a second. It may take a couple of bumps to
get it loose, but it almost always works. Be sure the breaker bar is not
hitting something that can break. Unfortunately, this trick doesn't help
you avoid proper ring gear blocking when you get to tightening the bolt.
Looking at the crank pulley, try not to turn the crank counter-clockwise.
It's not healthy for the timing chain system.
David.
