The Subaru / Robin 254-22501-10 Connecting Rod Assembly links the piston to the crankshaft, transferring engine power during each combustion cycle. Wear or damage to the connecting rod can affect engine operation, create internal noise, and lead to mechanical failure.

Common symptoms:

• Engine knocking noise.

• Excessive connecting rod wear.

• Loss of engine compression.

• Internal engine vibration.

• Damaged connecting rod assembly.

Engine Knocking Noise

Quick Check: Listen for knocking sounds from the crankcase while the engine is running.
