Cloyes High Performance Engine Camshaft Thrust Button P/N:9-202
Cloyes 9-203 camshaft thrust plate for the 1990-1993 Chevrolet C1500 V8 7.4L and other vehicles limits how far the camshaft moves front to back.
A worn engine camshaft thrust plate or a damaged block thrust surface can let the camshaft move front to back more than it should and can throw off chain alignment. Noise from the front of the engine does not by itself prove the thrust plate is at fault, since a stretched timing chain is a common source of it too.
The 1990-1993 Chevrolet C1500 V8 7.4L, the 1965-1969 Chevrolet Impala V8 6.5L and the 1967-1969 Chevrolet Camaro V8 6.5L are among the vehicles this plate fits, and many others are covered too. Each engine takes one plate, and this listing is one plate.

Will the Cloyes 9-203 fit a 1990-1993 Chevrolet C1500 V8 7.4L?

What is the Cloyes 9-203 camshaft thrust plate made of?
The Cloyes 9-203 is made of heat-treated steel bearing race material and measures 0.030 in thick.
Is machining required before installing this camshaft thrust plate?
Yes. The cam sprocket or the engine block must be machined .030" so the chain stays properly aligned.
Can this thrust plate repair a damaged block surface?
Yes. It can be used to repair a damaged engine block thrust surface, and it keeps wear off the block.
Does extra camshaft end play mean a worn thrust plate?
Not always. Extra front-to-back camshaft movement can come from a worn plate or a damaged block thrust surface, and an engine shop can measure end play to tell which.
