1938-1953 Clutch Disc

Thursday, February 11th, 2010

Chevrolet introduced their basic nine inch single disc clutch and corresponding diaphragm pressure plate in 1938. This pair was used in their cars and most 1/2 ton pickups with three speed transmissions through 1953. With about one million of these vehicles sold annually, one can quickly realize the high numbers of this clutch system that was at one time on the highway.

Even in 1954 with the introduction of the largerĀ 10 inch clutch disc and modified pressure plate on the new 235 six cylinder, the original design continued to sell very well as aftermarket replacements. Today, they still have a strong demand even though the majority of these over fifty year old vehicles are history. Most auto part stores now keep a pair in inventory for their walk-in customers.

1938-1953 Clutch

To add even more validity to this clutch’s durability, GM reintroduced it in the late 1960’s. General Motors was a major producer of full size passenger buses and the demand for most having the optional air conditioning was becoming strong. Almost all new buses would now be equipped with the option. The original small nine inch clutch was combined with the newly engineered large bus AC compressor. Once again, this proven clutch was serving automotive needs!

Therefore, if you find a source for new or core clutch assemblies used from the late 1960’s to at least the mid 1970’s in GM buses, they will also fit 1938-53 cars and small trucks.
