Of course that's the way to do it when you have the motor out and have the
time. You can get ARP bolts at most NAPA stores that have a performance
center. I've found them at Shuck's as well. They generally have a bolt
that will work. Don't use a lockwasher--at the kind of torque you need
they will spread. I don't much like them for anything. Do use some
locktite. Might even make some sense to try a little stud and bearing
locktite on the flywheel. It's just temporary and might help.
sorry I couldn't be there. Peyote's supposed to be done for next weekend.
I am racing the SCCA double regional in my Radical at PIR this weekend as
my consolation. I won today, (D sports Racer) though my times sucked and I
really felt sloppy.

We've seen this quite a bit in GT-6 situations also. The fix is to add
another locating pin, lighten the flywheel, maybe even consider an
aluminum
one, and use torque and loctite on the securing bolts. Lock washers are
not
a solution. Either grade 8 or aircraft alloy fasteners should be used.
Some
have also gone up one size on the fasteners used to secure flywheel to
crank
with desirable results. The key to the problem is the large mass the
flywheel poses vs the mechanical advantage of the sheer moment on the
fasteners and pin. All of the above will improve the situation. Ed
Ceilley
(GT-6) had a similar recurrent problem which was finally resolved by the
above procedures. That was years ago and he has not had a problem since.
As you I am sure realize this fix will require some effort and removal
of
the components, but the payback is there. I suggest, if you haven't
already,
have the crank balanced with the front pulley, flywheel and pressure
plate
installed by a dependable shop. Be sure to index the crank, flywheel and
pressure plate relative to eachother with some sort of markings for
future
assembly operations.
Best of luck.

Subject: Flywheel woes
Today (Friday), I was running my TR6 in the SOVREN Historics @ Pacific
Raceways in Kent WA, when during my qualifying session, I suddenly felt
a
vibration and the clutch wasn't operating fully. Upon removing my
transmission I discovered 3 of the bolts holding the flywheel on were
sheered
off and the last one was about half way out.
I'm looking for a fix I can do tomorrow(Saturday) and get me back on the
track. Anybody have any suggestions? I've heard of extra pins in the
crankshaft end and putting loctite around the crankshaft snout to
flywheel
connect as well as the bolts. The extra pins in the crank won't be
possible
until I take the motor apart. Any particular bolts work better? Lock
washers?
Any ideas?
