description

This brand-new forged camshaft is made of alloy steel, with hardened and NDT-inspected lobes and journals. It drives the right-bank rocker assembly. Compared with reman units, it retains sufficient material allowance and consistent heat treatment for long-term impact and high-temperature service. Pitting, journal scoring, deformed timing seat and blocked oil gallery lead to disordered combustion, unbalanced power, smoke and high fuel consumption. Severe failure causes valve-to-piston collision.

FAQ 

Q：Can this new camshaft replace reman 20R-1893 directly?
A：Yes, mounting dimension and cam lift are identical. New camshaft offers longer service life for heavy-duty application.

Q：Can only this right new camshaft be replaced while left one remains intact?
A：It is acceptable, but inspect left cam and bearings, and re-calibrate full valve timing.

Q：Does abnormal operation on one bank mean camshaft failure?
A：Check tappet wear, oil pressure and valve clearance first.

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