You have a flywheel? It needs to be machined...
Many are assembled w/o machining....but you want to replace the mainseal and
the "O" ring in the flywheel along with the pilot bearing..so why not take it
to the machine shop? Make sure if you are calling for prices that you tell 'em
it's a "stepped" fly wheel.they have to grind both the clutch surface and the
top surface to maintain the proper depth...takes longe/cost more..but not
alot.....
