description

This reman camshaft shaft follows full Cat Reman quality control process, including penetrant inspection, shaft straightening, cam surface fine grinding and spot hardness verification. It is made of integrated forged alloy steel, cam profile is machined to OEM C175 timing curve for high-displacement high-power combustion. It works together with 20R-6740, 20R-6741, 20R-6742 to form the complete valve cam group. This part is only the bare camshaft shaft, spacers and thrust washers are not included. The optimized hardened layer withstands continuous high temperature and impact load. Different C175 camshaft shaft part numbers have unique profiles and are not interchangeable. Verify engine serial number before ordering.
