Speedway Motors 91015637 Details

Speedway developed these 10.5" clutch pressure plates for sportsman circle-track racers. Includes a lightweight, stock-appearing pressure plate that features a ductile iron pressure ring. Can be used with solid or sprung hub clutch discs with organic or ceramic friction surfaces.

Tech Tip:  When installing a new clutch, be sure to follow the manufacturer's instructions for correct set-up.  You should also replace the pilot bushing/bearing.

Tech Tip:  To extend the life of your expensive racing clutch you should not use it to load the car on or in your trailer.  The amount of slippage this causes is worse than a night of racing.

Which hydraulic release bearings work with this? The engine is a '51 Mercury flathead. Stamped steel style bell-housing, I think it is from a '49 Ford. Trans has the front bearing retainer from a Saginaw 4-speed. Trans is mounted directly to the bell-housing without an adapter.

46 Flathead V8 to 32 Three Speed I have a 1928 Model AV8 Pickup I am putting together. Using a 1946 Flathead V8 and a 1932 three speed. I had the motor and tranny hooked up and in the pickup, and thought the motor had seized up. I loosened the bell housing bolts and the motor turns over fine. The pressure plate must be making contact with the bell housing Therfore I think I must have the wrong pressure plate. Can your tell me which pressure plate I should be using. Thanks Bruce
