<VV> Fly wheel question

[Frank DuVal]

I've had real good luck bolting my own.I DO have a local shop that 
balances it for me. I use the 5/16-24 grade 8+ bolts and self locking 
nuts. This means I need to grind some off the heads of the bolts when 
finished, hence the need for balancing.

I start by drilling off the heads of the rivets from the engine side of 
the flywheel. Center punch the rivet head and drill a small hole to 
start, say 1/16" or so maybe a 1/4" deep. No need to go all the way 
through.  Now use a 5/16" drill bit. Just drill enough to get the head 
to pop off. Now drive the rivet out using a punch almost 5/16" diameter. 
If the rivets come out easily, the holes are wallowed out. Stop, as you 
need to have the ability to center the parts. Do a maximum of 4 rivets a 
a time, 15 minutes apart if it were a clock face. This will keep 
everything in alignment (if it was to start...)

Install the new bolt with the head toward the engine and the nut up 
inside the recess on the pressure plate side. I try to keep a flat of 
the bolt head parallel to a line tangent to the flywheel. This is to 
allow easier grinding for clearance to the lower bellhousing bolts. 
Torque to 18 - 20 ft-lbs ( or whatever the instructions say that came if 
you buy a bolt kit). Grind a bevel on all the bolt heads evenly for 
clearance.
