description

This is not a basic reconditioned part. Returned cores are fully disassembled, thoroughly cleaned and crack-tested; defective cores are scrapped. Qualified cores go through journal grinding, cam lobe profile restoration and the latest Cat engineering updates. Proprietary heat treatment restores surface hardness and core toughness to original specs. On C18 engines, this camshaft drives valve train and works with the HEUI fuel system to manage gas exchange, which defines torque delivery, combustion efficiency and emission performance under heavy climbing loads. It fits 770G/772G off-highway trucks, 988K wheel loaders, 390F excavators, PL87 pipelayers and stationary generator sets, built for continuous full-load, high-vibration mining conditions in the Middle East and Africa.
