This is a Caterpillar Pushrod for the valve train system, crucial for transferring motion from the camshaft to the rocker arms, thereby controlling valve operation. Manufactured to precise tolerances and durable materials, it ensures consistent valve timing and lift compared to a worn or bent pushrod. Operators might notice engine misfires, rough idling, or a loss of engine power when this component fails.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
An initial symptom of a failing pushrod can be an audible ticking or tapping noise from the engine, particularly at idle. If ignored, the engine may develop a rough idle, misfires, and a noticeable loss of power as valve timing is compromised. Continued operation risks further damage to the camshaft and cylinder head components.
Ensure the pushrod ends are properly seated in both the lifter and the rocker arm socket before reassembling the valve train. Avoid rotating the engine until all pushrods are correctly installed and the valve train is properly adjusted.
When replacing pushrods, inspect the camshaft lobes, lifters, and rocker arms for wear or damage.
