description

This 423-7587 camshaft assembly is integrally forged from high-purity alloy steel. Cam profiles are precision ground to OEM lift curve for late-version C18 engine with deep carburizing quenching. Timing gear and locating spacer are pre-assembled for direct installation. It synchronizes intake, exhaust and fuel timing, fixing weak power, high exhaust temperature, gear housing noise and unstable idle. It fits continuous full-load dusty open-pit mining operation, complete timing assembly for C18 engine, not interchangeable with 423-7586.

Part No.：423-7587
Name：Camshaft Assembly
Material：High-purity alloy forged steel
Process：Integral forging + carburizing quenching + multi-station precision grinding
Package includes：Camshaft body, timing gear, locating spacer
Application：Cat C18 engine, 749 mining truck, 988K wheel loader

Product Advantages

1. Pre-assembled gear and spacer sets eliminate the need for press-fitting and calibration, shortening major overhaul turnaround times.
2. Cam lift and phasing are matched to the latest C18 calibration specifications, requiring no software reflashing after installation.
3. A deep case-hardened (carburized) layer ensures the cam lobes resist pitting and spalling, even under sustained high-temperature, heavy-load operating conditions.
4. Strict control over the concentricity of the long camshaft minimizes uneven wear across multiple journals, extending the interval between major engine overhauls.
5. Factory-verified for shaft runout, surface hardness, and gear backlash—an ideal, ready-to-use solution for bulk stocking in mining maintenance operations.

FAQ 

Q：Can 423-7587 replace 423-7586 directly?
A：Not interchangeable. Timing phase and gear parameters differ for different C18 revisions, causing valve interference.

Q：Can the camshaft be reused after light journal scratches are polished and measured?
A：It can be used temporarily if dimension stays within tolerance. Deep grooves require replacement to avoid bearing seizure.

Q：How to store this camshaft assembly properly?
A：Hang vertically, apply anti-rust oil on gear teeth and cam lobes, cover with dust film and avoid impact.

Q：Is oil and filter change recommended while replacing this camshaft assembly?
A：New engine oil and filter are recommended to protect new cam lobes from oil impurities.
