2. RE-RIVETED FLYWHEELS – Hot Forged
These flywheels are re-riveted using hot rivets for a tighter, stronger fit. They are then machined and
balanced to give you a better than stock, original style flywheel. Original Corvair flywheels were
assembled to an alignment spec. of .020 or more. These units have been aligned to .005 for
axial "edge" run-out and .008 or less radial "face" run-out. Unlike originals, these are then
precision machined and assembled with "Red Hot Forged Rivets". The factory method was to
press the rivets in cold. This resulted in loose rivet failures. The Red Hot rivet method makes
a tight secure bond that cannot be matched, even by bolting and has proven to be reliable
with NO rivet failures since 1976 and over 3000 flywheels rebuilt in this way, guaranteed.
The final step in our process is to dynamically balance the flywheel in steps, up to 3500
rpm, producing the finest flywheel available for Corvairs. It is highly recommended that the
new clutch pressure plate and disc be balanced with the flywheel before installation. Major
imbalance issues are directly the result of un-balanced or poorly balanced clutch pressure
plates. Wash away protective cosmoline coating with mineral spirits or other solvent before
installation. PRICE INCLUDES A REFUNDABLE CORE FEE.

CLUTCH DISCS
Best Rebuilt Discs: All used discs are disassembled, then installed on a machine that spins them and checks for run out. If a disc cannot be
corrected to new tolerances then it is thrown out. If it passes this phase then the spring tabs are checked and if acceptable a quality lining is
installed. This family-owned business has been rebuilding for 60 years. 9" will fit all Corvairs. PERFORMANCE DISC – SEE PAGE 107
