description

The 242-0675 is complete camshaft assembly for C9 engine, supplied with camshaft, timing gear, thrust washer and retaining hardware. It eliminates separate sourcing of timing components. This electronic engine powers mid-to-large excavators under heavy shock and frequent load changes. The camshaft drives both valve train and fuel pump. Lobe pitting, spalling or journal scoring leads to power loss, rough idle, high fuel consumption and smoke. Severe damage causes valve-piston contact. The pre-assembled kit simplifies overhaul and avoids mismatched timing parts.

Part No.：242-0675
Name：Camshaft Assembly
Fit Models：CAT C9
Equipment：330D, 336D excavator, 966H wheel loader

Product Advantages

1. Pre-matched from factory, concentricity and end play are pre-checked for faster overhaul
2. Dedicated cam profile for C9 electronic fuel system, delivering strong low-speed torque and stable operation under load swing
3. One-piece forged blank with dense grain, resisting fatigue shock for long working cycles on site
4. Full kit supply reduces separate part sourcing and avoids timing component mismatching

FAQ 

1. Can 242-0675 interchange with 242-0673?
Interchange is not recommended. They have different timing specs for different C9 calibrations, altering power and smoke performance.

2. Does it fit C9.3 engine?
No. C9 and C9.3 differ in cylinder head design, cam lift and fuel calibration, non-interchangeable.

3. Can the included gear with light tooth pitting stay in service?
Tooth pitting is fatigue damage and spreads rapidly under excavator shock load, inspection is required.

4. What risk if I install new cam assembly and reuse old lifters?
Mismatched contact surfaces accelerate lobe spalling during break-in and lead to early failure.
