description

This camshaft assembly is made of solid forged alloy steel, with magnetic particle inspection, shaft straightening, cam surface fine grinding and hardness spot check. Its cam profile is tuned for ADT climbing and long-cycle haulage, balancing low-end torque and exhaust flow for C13 ACERT aftertreatment. The kit includes camshaft body, thrust washer and woodruff key. It differs from 223-7464 excavator version and 223-7467 loader version in calibration, not interchangeable. Verify engine serial number before purchase.

Product Advantages

1. OEM ADT-specific calibration, strong torque on grade, reduce power drop and high exhaust backpressure while climbing
2. Dense hardened cam lobes resist frequent load changes and lower pitting risk
3. Tight coaxiality control reduces uneven journal wear and extends bearing service life
4. Pre-packed with thrust washer and woodruff key to avoid clearance adjustment error
5. Stable spare stock for articulated truck fleet maintenance in Southeast Asia and African open mines

FAQ 

Q: Can 294-0503 replace loader camshaft 223-7467 directly?
A: No. Different calibration targets, ADT climbing tune vs loader bucket tune, ECU will not match.

Q: Does the assembly include thrust washer and woodruff key?
A: Yes, thrust washer and woodruff key are included for direct fitting.

Q: What maintenance note for frequent heavy haulage on mine ramps?
A: Use Cat genuine oil and shorten filter interval to protect cam and journals.

Q: Is ECU calibration check required after camshaft replacement?
A: Same part number replacement does not require reprogramming. Cross-part swap needs ET timing and calibration validation.
