2420673 Camshaft As — Cat 140M 140M 2

This is a camshaft assembly, a fundamental component within the engine's valvetrain responsible for controlling the opening and closing of intake and exhaust valves. Manufactured to meet rigorous CTP aftermarket standards, it ensures precise timing and lift for optimal engine performance and efficiency. Operators may experience a noticeable loss of engine power, rough idling, increased exhaust smoke, or poor fuel economy when this camshaft assembly begins to wear or fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial symptoms of a failing camshaft include rough idling and a slight decrease in engine power. As wear progresses, valve lift may become inconsistent, leading to increased exhaust smoke and significantly reduced performance. The worst outcome is severe engine damage due to improper valve timing and potential component failure.

Installation Tip

Ensure all bearing surfaces and lobes are meticulously cleaned and lightly oiled before installation to prevent initial wear. Never reuse old timing gears; always install new ones with the camshaft assembly.

Service Note

Inspect and replace lifters, valve springs, and timing gears if any signs of wear or damage are present when installing the camshaft assembly.
