description

This genuine Cat reman camshaft is made of carbon alloy steel. All cam lobes and journals are inspected, heat-treated and super-finished, integrated with timing gear. It is installed inside cylinder head to drive rocker and tappet assembly. Pitting lobes, scored journals, worn gear teeth and blocked oil gallery lead to incorrect valve timing, power loss, abnormal noise and high fuel consumption. Severe failure causes valve-to-piston collision.

FAQ 

Q：Can 10R-7157 swap with new 243-0551 directly?
A：Yes, mounting dimension, cam lift and gear parameter are identical. 10R-7157 is reman version with better cost performance.

Q：Does noisy valve train mean this camshaft failed?
A：Check tappet wear, oil pressure, valve clearance and timing gear first.

Q：Can old cam bearings be reused with this reman camshaft?
A：Not recommended. Worn old bearings will cause early scoring, replace bearing set together.

Q：What risk if oil hole misaligned after installation?
A：No lubrication on cam contact surface, dry friction causes lobe scoring and seizure quickly.
