description

This 438-6132 camshaft assembly is forged from high-toughness alloy steel. Its cam profile is optimized for uphill haulage and strong mid-range torque. Timing gear, locating spacer and thrust flange are pre-assembled and phase-checked. It synchronizes valve events and fuel injection, fixing power loss on slope, high exhaust temperature, gear noise and smoke under heavy load. It is built for frequent start-stop and variable slope load, not interchangeable with marine, generator or stationary pump camshafts.

Part No.：438-6132
Name：Mining Camshaft Assembly
Material：High-toughness alloy forged steel
Process：Integral forging, carburizing quenching, segmented precision grinding, dynamic balance, pre-calibration
Package includes：Camshaft body, timing gear, locating spacer, thrust flange
Application：Cat large mining truck engine, open-pit heavy haul power unit

Advantages

1. Mining haulage cam profile, extended fuel injection window for steady torque on slope
2. Wider thrust flange, resisting axial impact from load change and stabilizing timing clearance
3. Balanced hardness and toughness on cam surface, resistant to chipping under repeated shock
4. Pre-assembled unit, saving fitting time in cramped engine compartment of mining truck
5. Concentricity, gear backlash and hardness tested individually, suitable for mine spare stock

FAQ 

Q：Can 438-6132 mining camshaft assembly replace marine 438-3064?
A：Not interchangeable. Cam angle, thrust design and fuel timing differ, causing power loss and timing jump.

Q：Can the camshaft be reused after light journal scratches polished?
A：It can be used temporarily within tolerance. Deep grooves require replacement to avoid seizure on haul route.

Q：How to store this camshaft assembly properly?
A：Hang vertically, apply anti-rust grease on gear teeth and cams, wrap dust film and keep away from sand and dust.

Q：Is oil and filter change recommended after installation?
A：Recommended, to protect new cam lobes from debris and guarantee reliable haulage.
