100-7409 Camshaft — Cat 3406

This is a camshaft, a crucial rotating shaft with lobes that operate the engine's intake and exhaust valves. It is precision-machined from hardened steel to ensure accurate timing and durability under high stress, differing from a worn part by its sharp lobe profiles and correct dimensions. Operators may experience poor engine performance, misfires, or difficulty starting the engine when the camshaft is worn or damaged.

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

A failing camshaft may initially present as a slight loss of engine power or irregular idling. Continued operation can lead to noticeable misfires, increased fuel consumption, and potential damage to valve train components.

Installation Tip

Thoroughly clean the camshaft bearing journals in the engine block before installation to prevent premature wear. Ensure the camshaft is properly lubricated with assembly lube on all bearing surfaces and lobes before insertion.

Service Note

Inspect valve lifters, timing gears, and camshaft bearings for wear and proper function when replacing the camshaft.
