description

This Reman camshaft follows Caterpillar remanufacturing standards. The core is inspected by ultrasonic crack detection. Cam lobes are re-profiled and induction hardened, journals are precision ground. Lobe lift, duration and timing angle comply with OEM 3406E specifications. It fits highway trucks, D350E II, D400E II articulated dump trucks and generator sets with 3406E and 3456 engines. It is widely used for overhaul in mining and long-haul transport. It fixes lobe pitting, spalling, journal scoring and timing deviation, stabilizes power delivery and reduces high fuel consumption and rough idle. It is an economical alternative to new camshaft for fleet maintenance.
