Doug---The three pins are for aligning the clutch, but ordinarily don't need to
be removed after doing so. They should be in the flywheel tight enough to hold
fast. You should find the new pins very tight, unless the flywheel holes have
opened up for some reason. The clamping pressure of the six clutch-to-flywheel
bolts should relieve the pins from doing any holding work.
Of course the clutch alignment tool should slip in and out easily after the
clutch bolts are tightened.

A while back my engine wouldn't crank, jammed hard; but everything from the
clutch back was nice and free. I thought perhaps the backup bolt I installed
on the throwout bearing fork had lost its nut and jammed the ring gear
(perhaps due to stupidly re-using a nylock nut or somesuch). Nope, wasn't
that. Two of the three small alignment pegs for the flywheel/pressure-plate
interface came out, and one jammed between the ring gear and the case (no
damage, just a few light scratches on the case, but the pegs are obviously
toast). All the bolts were fully tight, and I re-torqued 'em with no
movement.
Two questions:
1. What would cause these to pop out?
2. Are they really necessary for operation, or are they just for installation
alignment?
Okay, three ... three questions:
3. Did I screw up somewhere?
