description

This 453-1872 camshaft assembly is forged from fine-grain alloy steel. Its cam profile is optimized for long low-speed grading work, maintaining stable air charge when cutting resistance changes. Timing gear, locating spacer and integrated thrust flange are pre-assembled and phase-checked. It coordinates valve events and fuel injection to fix speed drift, smoke under heavy cutting, gear noise and rough idle. Grader runs in long steady load cycles, its timing and heat treatment differ from loader, excavator and compressor camshafts.

Part No.：453-1872
Name：Camshaft Assembly for Motor Grader
Material：Fine-grain alloy forged steel
Process：Integral forging, carburizing quenching, segmented precision grinding, dynamic balance, pre-calibration
Package includes：Camshaft body, timing gear, locating spacer, integrated thrust flange
Application：Cat motor grader, road slope cutting and subgrade leveling power unit

Advantages

1. Grader-specific cam profile, extended intake duration for steady speed under variable cutting resistance
2. Integrated thrust flange, stable axial limit and consistent timing clearance during long working hours
3. Uniform hardened cam surface, resistant to fatigue pitting under prolonged moderate alternating load
4. Pre-assembled unit, saving fitting time in cramped engine compartment of grader
5. Concentricity, gear backlash and cam profile inspected individually, suitable for road fleet spare stock

FAQ 

Q：Can 453-1872 grader camshaft assembly replace loader 453-1871?
A：Not interchangeable. Cam angle, fuel timing and thrust design differ, causing unstable speed and power.

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 during grading.

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 construction dust and moisture.

Q：Is oil and filter change recommended after installation?
A：Recommended, to protect new cam lobes from debris for long continuous grading work.
