[DeTomaso] Techno question: aluminum flywheel washers

[Steve Hawkins]

I believe the issue is to be carefull what bolts you use.  Will can correct
me if I'm remembering incorrectly but, I think the stock bolts have too long
of a shoulder on them and the head doesn't contact the flywheel surface so
the washers are required to take up the gap.

I didn't use washers on my Fidanza flywheel bolts.  I use ARP bolts.

There wasn't any galling under the bolts.

The bolts have always been torqued properly during disassembly (2
disassembles so far - hoping #3 is at least yr 2010)

By the way, at one time I measured the thickness of the flywheel at the
flange - if I recall correctly, it was the same thickness as the stock
flywheel.

noise would go away.  When I finally removed the engine/gearbox and examined
the inside of the bell housing I discovered that the bolts that held the
pressure plate to the flywheel were a tall hex head bolt and had been
kissing the reinforcing bosses inside the bell housing, causing the
"bearing" noise.  The ARP bolts I bought for both the pressure plate and the
flywheel are a very low style fastener and will not create interference
problems in either location.  I would highly suggest that you pay a buck or
two more and get the ARP fasteners (Summit, Jegs, Doug Herbert, etc.).
