description

It is remanufactured from qualified forged steel cores via liquid penetrant crack inspection, journal grinding and cam profile restoration, with Cat’s official ACERT engineering updates to boost lobe fatigue resistance. Unlike 10R-7155 tuned for highway cruise, 20R-1137 is optimized for low-end torque delivery. It maintains stable combustion under frequent start-stop and variable load cycles typical in mines. It matches 773G haul trucks, 980K wheel loaders, D9T dozers and crushing power units, built for dusty, highly variable mining sites in Africa and the Middle East.

Product Advantages

1. ACERT-specific lift profile delivers strong low-end climbing torque and adequate air intake to reduce smoke under heavy loads.
2. Strict coaxiality check keeps oil film intact under cyclic shock and vibration and prevents bearing seizure.
3. Cores with hidden cracks are rejected during remanufacturing, delivering better reliability than basic reworked parts for mining duty.
4. Core return credit reduces purchase cost versus new camshafts, ideal for bulk stock preparation for mining fleets.

FAQ 

Q: Can 20R-1137 interchange with 10R-7155?
A: No. Both are Reman C15 camshafts, but calibrated for different applications. 20R-1137 is ACERT mining variant while 10R-7155 is highway version with different cam profile.

Q: How many 20R-1137 camshafts are required for one C15 ACERT engine?
A: C15 is inline engine, only one camshaft is fitted per engine.

Q: Can lightly worn original cam gear be reused with this Reman camshaft?
A: It is permitted after backlash inspection. Mismatched new and used gears accelerate wear, replace the gear if backlash exceeds service limit.
