1N4406 Camshaft Gp — Cat 120B 12G

This camshaft group is a fundamental component of the engine's valvetrain, controlling the opening and closing of intake and exhaust valves to regulate the flow of air and exhaust gases. Manufactured to meet stringent OEM quality standards, it ensures precise timing and lift, unlike a worn camshaft with flattened lobes or excessive play. Operators may experience rough idling, reduced engine power, increased exhaust emissions, or audible ticking noises from the engine when this camshaft group 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 signs of camshaft wear include a rougher engine idle and a noticeable decrease in overall engine power. If ignored, this can lead to increased fuel consumption, visible exhaust smoke, and audible ticking or knocking sounds from the engine. The most severe consequence is potential damage to pistons and cylinder heads due to improper valve timing and sealing.

Installation Tip

Ensure the camshaft bearing surfaces in the engine block are meticulously clean and properly lubricated before installation. Never rotate the camshaft without proper valve train components installed, as this can cause damage.

Service Note

Inspect and replace lifters, valve springs, and timing gears/belts as part of a comprehensive valvetrain overhaul.
