description

The 374-4669 is one-piece forged camshaft for C18 inline six-cylinder engine. Its cam profile coordinates valve lift and fuel pump drive timing, serving as the key valve train component for heavy-duty C18 power packs. C18 usually runs continuously under heavy cyclic loads in open-pit mine and port sites. Lobe pitting, spalling or journal scoring leads to power loss, excessive fuel consumption and persistent smoke. Severe failure may trigger valve-piston contact and catastrophic breakdown. This camshaft is supplied without timing gear, allowing reuse of serviceable original gear for cost-effective overhaul.

Part No.：374-4669
Name：Engine Camshaft (without gear)

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

Product Advantages

1. OEM calibrated cam profile matches C18 fuel system, synchronizing valve and fuel delivery timing for stable heavy-load torque
2. One-piece forged blank with dense grain structure, resistant to cyclic shock for non-stop full-load mine service
3. Uniform hardened layer on lobes and journals delivers good seizure and abrasion resistance against contaminated lubricating oil
4. Supplied without gear. Serviceable original gear can be retained separately to cut overhaul investment

FAQ 

1. Does 374-4669 fit C15 engine?
No. C15 and C18 differ in cam lift, journal dimension and fuel timing reference, non-interchangeable.

2. Can original gear with light tooth pitting stay in service?
Tooth pitting is fatigue damage. Wear accelerates rapidly under heavy mining truck load, inspection and replacement are recommended.

3. 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 roller lifters.

4. What risk if I install new camshaft and reuse old lifters?
Mismatched contact surfaces will trigger rapid lobe pitting and spalling during break-in and lead to early failure.
