This camshaft is a crucial component within the engine's valvetrain system, responsible for operating the intake and exhaust valves. Manufactured to high standards, it offers superior wear resistance and precise timing compared to a worn camshaft. Operators might observe rough idling, loss of engine power, or difficulty starting the engine when this part is failing.

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

Early failure may manifest as ticking noises from the engine or a noticeable decrease in engine power. If left unaddressed, the valvetrain can become erratic, leading to poor fuel efficiency and potential internal engine damage. Continued operation risks severe damage to pistons and cylinder heads.

Installation Tip

Lubricate the camshaft lobes and bearing journals with assembly lube before installation to ensure proper initial lubrication. Ensure camshaft timing marks are precisely aligned with the crankshaft timing marks.

Service Note

Inspect camshaft bearings, lifters, and timing gears for wear or damage when replacing the camshaft.
