Gold Star Racing Clutches has been involved in Mini-Stock circle track racing since coming on the racing scene in 1989. The Gold Star Racing Clutch products are used primarily in circle track Mini-Stock, Derby, SCCA Road Racing, Vintage Road Racing, and Rally competitions – specializing mainly in 2.0-2.5 liter, single and dual disc racing clutch applications for Ford, GM, and Toyota.
All of the Gold Star Racing Clutches products are made in the USA using US produced aircraft grade billet aluminum and high strength steel. Some components are heat treated and stress relieved as required for thermal stability and wear durability. They recommend and use ARP hardware.
We asked for some quick tips and tricks on single disc clutch assembly, and owner Guy Apple was happy to provide us with his assembly instructions:
Inspect the transmission pilot bushing or bearing. If worn, replace the bushing. A worn bushing or bearing can cause transmission failure and clutch drag. Start the installation by removing the clutch cover, then evenly remove the 6 lock nuts & washers to remove the pressure plate and disc.
You will want to clean threads & bolts with a grease remover for obvious reasons. Then bolt the flywheel to the crankshaft. Remove one bolt at a time and apply red threadlocker and torque to specified torque specs. Mark bolt and continue to next bolt until all 6 are torqued. For example, the 2300 Ford uses 10 mm bolts torqued to 65-lbs/ft. Gold Star recommends using ARP Bolts for this application.
Place pieces against flywheel in the order they were taken apart:
A. Clutch disc (cone facing transmission)
B. Pressure plate flat side against the disc
C. Cover assembly. Slide alignment tool through cover assembly, pressure plate, and disc into the pilot bearing and evenly tighten the 6 lock nuts down to 22-24 lbs/ft.
Adjust clutch linkage for 1.5-inch of free play at the pedal. Check free-play at the end of each race. As disc wears, the amount of free play decreases.
