20768518 — Connecting Rod Voe20768518 20551431 For Volvo Engine D6D D4D Td420Ve Tad420Ve Tad620Ve Excavator Ec140B

This connecting rod is a vital link within the engine's reciprocating assembly, transferring the force from the piston's linear motion to the crankshaft's rotational motion. Manufactured to precise Volvo specifications, it offers superior strength and fatigue resistance compared to a worn or bent rod. Operators may hear distinct knocking sounds from the engine, experience significant power loss, or observe oil pressure drops when a connecting rod begins to fail.

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

The initial symptom of a failing connecting rod is often a distinct metallic knocking sound originating from the engine, which may increase with engine speed. If ignored, this can progress to severe engine vibration, a significant loss of power, and a noticeable drop in oil pressure due to increased clearances. Continued operation risks catastrophic internal engine damage, potentially requiring a complete engine rebuild.

Installation Tip

Always use new connecting rod bolts and nuts, and torque them to the manufacturer's specifications in the correct sequence to ensure proper clamping force. Ensure the connecting rod bearing surfaces on both the rod and crankshaft are meticulously clean and properly lubricated before assembly.

Service Note

Inspect the piston, piston pin, cylinder liner, and crankshaft journals for wear or damage when replacing a connecting rod.
