description

The 332-7308 is one-piece forged camshaft for C15 inline six-cylinder engine. Its cam profile coordinates valve lift and fuel injection timing, serving as the key valve train component for articulated truck power packs. Articulated trucks usually run fully loaded on undulating mine and dirt sites with frequent start-stop and load changes, subjecting the camshaft to cyclic impact. Lobe pitting, spalling or journal scuffing causes power loss, exhaust noise and high fuel consumption. Severe damage may trigger valve-piston collision and catastrophic engine breakdown.

Part No.：332-7308
Name：Engine Camshaft

Material：Carbon Steel, Alloy Steel
Matching Components：Roller lifters, cam bearings, timing gear, thrust washer

Maintenance & Replacement Tips

1. Inspect all roller lifters and cam bearings during replacement. Replace worn components with excessive clearance
2. Clean cylinder head galleries and camshaft oil passages thoroughly. Mine-site oil contamination easily scratches cam lobes
3. Follow C15 service manual strictly for timing alignment. Misaligned gear disrupts valve and fuel timing
4. Pre-lube before cranking. Listen for abnormal gear housing noise and monitor oil pressure for the first 100 working hours

FAQ 

1. Can 332-7308 interchange with 332-7301 camshaft for C15 6NZ?
No. They differ in cam lift and timing reference for different C15 sub-series. Verify engine serial number before ordering.

2. Can the camshaft stay in service with scattered shallow pitting and no crack?
Light isolated pits can be monitored temporarily. Replace it if pitting spreads or spalling occurs to protect lifters.

3. What risk if I install new camshaft and reuse old lifters?
Mismatched contact surfaces will cause rapid pitting and spalling during break-in and lead to premature failure.

4. Does it fit C18 engine?
No. C15 and C18 differ in block structure, cam mounting dimension and lift profile, non-interchangeable.
