21112696 Push Rod | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta push rod engineered for the TAMD165C-A fuel-injector internal mechanism. This component is the injector push rod or pressure pin transmitting spring force to the nozzle needle. Correct selection requires the complete Volvo Penta product number and serial number because adjoining components, mounting arrangements and production revisions can change within the same engine or transmission family.

🚤 Compatibility

Typically suits:

• Volvo Penta TAMD165A
• Volvo Penta TAMD165C

• Engine Family: TAMD

⚙️ Key Features

• Precision-ground ends transfer spring load without side force
• Hardened surface resists repeated high-frequency contact
• Exact length affects injector opening-pressure adjustment
• Straightness is critical for free movement inside the injector
• Installed only during clean-room injector overhaul

🔌 Function

Transfers the calibrated spring force to the nozzle needle so the injector opens and closes at the specified fuel pressure.

⚠️ Common Signs of Failure

• Pitted or worn contact ends
• Bent rod causing needle sticking
• Incorrect opening pressure after assembly
• Injector dribble or delayed closing
• Uneven cylinder combustion and smoke

🛠️ Service Notes

• Check every pushrod for straightness by rolling it on a known flat surface, and inspect both ends for wear, pitting, scuffing or heat discoloration
• A worn or bent pushrod is a symptom — check the rocker, the tappet or lifter and the valve itself before fitting new, or the new rod will go the same way
• Never try to straighten or reuse a bent pushrod, and never shorten or modify one
• Confirm each rod is properly seated in its tappet and in the rocker socket, with the ends oiled on assembly, before any rocker fastener is tightened
• Set the valve clearances and tighten the rocker gear to the procedure and figures given in the workshop manual for your engine, then turn the engine over by hand to confirm everything is free
