description

This is a brand-new forged camshaft, different from reman 20R-1145 for C15 ACERT. Its cam profile is designed for classic C15, C18 and 3406E, not for ACERT emissions engine. Cam lobes actuate hydraulic tappets and rockers to regulate valve timing, reliable for large displacement heavy machinery.

It is forged alloy steel with high-frequency hardened cam surface for good fatigue and impact resistance. Internal oil gallery feeds journals and cam lobes continuously to reduce scoring and spalling risk under heavy load.

It fits Caterpillar C15, C18, 3406E, 3408E engine, widely used on 980H/988H loader, D8R/D9T dozer, 621G/631G/637G scraper, 374D/390D excavator and pipelayer. Timing gear sold separately, verify serial number and avoid mixing with ACERT camshaft.

Product Advantages

1. New forged alloy steel blank, uniform hardened cam surface, no coating peeling risk of reman units
2. OEM classic lift profile for C15/C18/3406E, matches older fuel system for stable combustion
3. Integrated through oil gallery for steady lubrication, suitable for long continuous scraper operation
4. Pre-delivery runout and phase inspection, tight coaxiality, stable timing and smooth idle after installation

FAQ 

Q: What faults are caused by pitting and spalling on cam lobes?
A: Reduced valve lift, poor gas exchange, power loss and higher fuel consumption with valve train noise, rough idle and misfire in severe cases.

Q: Can 332-7298 replace 20R-1145 for ACERT engine?
A: No. Lift and phase are totally different. ACERT ECU and aftertreatment system are incompatible, will trigger derate and abnormal operation.

Q: What happens if oil passage is blocked?
A: Cam journals and lobes lose lubrication and score rapidly, leading to premature camshaft failure and stuck tappets.

Q: What risk if I reuse old cam bearings?
A: Worn out-of-round bearings create uneven clearance and score the new forged journals quickly.
