Common questions Americans ask about camshaft retainer thrust plates
What does a camshaft thrust plate do?
The thrust plate bolts to the engine block in front of the camshaft and limits how far the cam can shift forward and backward. Without it, the cam would walk under valve spring pressure and damage the timing components and front of the block.
How do you check camshaft end play?
Mount a dial indicator against the front of the camshaft, pry the cam forward, zero the indicator, then push the cam back and read the total movement. Most OHV V8 engines spec 0.001 to 0.007 inch of end play.
How much does a camshaft thrust plate cost?
OE-replacement thrust plates run $10 to $30. Performance hardened plates from Comp Cams or Crower cost $40 to $90. Cam thrust button assemblies for roller cam applications range from $40 to $150.
When should I replace the camshaft thrust plate?
Replace the thrust plate whenever you install a new camshaft, during a timing chain job, or anytime cam end play measures beyond service spec. A scored or grooved plate must always be replaced because it can no longer hold proper position.
Can I reuse the cam thrust plate?
Inspect the wear surface for grooves, scoring, or polishing. A clean plate with no visible wear can be reused. Any visible groove, especially one you can feel with a fingernail, means the plate has worn beyond service limits and must be replaced.
What happens if the cam thrust plate fails?
A failed thrust plate lets the camshaft slide forward into the timing chain, which can break the chain, crack the front cover, or damage the cam gear. Severe end play also throws off ignition and valve timing.
Where is the camshaft thrust plate located?
The thrust plate sits between the front face of the camshaft and the engine block, just behind the cam gear. You must remove the timing cover, timing chain, and cam gear to access it. On some engines it's part of a one-piece front cover assembly.
Do roller cams use a thrust plate or thrust button?
Most performance roller cam setups use a thrust button installed between the cam and the timing cover. The button rides against the inside of the cover and limits forward cam movement. Stock roller cams typically retain the conventional thrust plate.
How long does a cam thrust plate last?
Quality thrust plates last 150,000 to 250,000 miles in normal service. High-RPM use, aggressive valve springs, and frequent cold starts wear the surface faster. Always inspect during any timing chain or cam replacement.
