description

This 463-5442 camshaft assembly comes pre-assembled with timing gear and matching bushing, eliminating separate gear selection. It drives valve train via cam profile to precisely control intake and exhaust valve timing for stable combustion. Made of integrated alloy forging, cam lobes are carburized and quenched for fatigue and impact resistance, ideal for long continuous heavy-duty operation of excavators and loaders, a complete replacement kit for engine overhaul.

Part No.：463-5442
Name：CAT camshaft assembly
Application：CAT heavy construction machinery engine
Components：Camshaft + timing gear + bushing
Surface treatment：Carburizing and quenching
Drive type：Gear timing drive

Advantages

1. Pre-assembled kit with pre-calibrated gear phase, saves installation time and reduces wrong timing risk
2. Uniform carburized hardening layer, anti-pitting on cam surface, stable service life under frequent start-stop condition
3. Gear is hot-fitted on shaft, stable torque transmission, less slipping or jumping teeth
4. Strict coaxiality of shaft journals, low running friction, reduce abnormal wear of cam bearings

FAQ 

Q1：Can the timing gear of 463-5442 be removed and replaced separately?
A：Separate removal is not recommended. The gear is hot-fitted, disassembly may damage shaft journal. Replace the whole assembly preferentially.
Q2：Can the assembly keep working with light scratches on gear teeth?
A：Shallow scratches can be monitored temporarily. Replace the whole set once chipping, peeling or cracks appear.
Q3：Must tappets be replaced together with this camshaft assembly?
A：Camshaft and tappets are friction pairs. Synchronous tappet replacement is recommended for overhaul.
Q4：What will happen if timing marks are misaligned during installation?
A：It will cause low power, black exhaust smoke, valve-piston collision and severe engine damage.
