FAQ

Q1: How do I confirm that this connecting rod (6245-31-3100) fits my Komatsu engine?

To ensure correct fitment, please verify your engine model number (should be 6D170) and check the existing connecting rod part number. The OEM number 6245-31-3100 is typically stamped on the original part. We recommend comparing the physical dimensions (big end bore diameter, small end bore diameter, and center-to-center length) with your current rod before installation. If you have any doubts, please contact our technical support team with your engine serial number for assistance.

Q2: What is the recommended installation procedure for this connecting rod?

Installation should be performed by a qualified diesel mechanic following the Komatsu service manual for the 6D170 engine. Key steps include: cleaning the connecting rod and cap mating surfaces, torquing the cap bolts to the manufacturer’s specified torque in the correct sequence, checking bearing clearance using plastigage, and ensuring proper piston pin fit. Always use new connecting rod bolts and nuts during reassembly to prevent fastener fatigue failure.

Q3: What maintenance should I perform after installing a new connecting rod?

After installation, perform a thorough engine break-in procedure as recommended by the engine manufacturer. Monitor oil pressure closely during the first 50 hours of operation. Check and retorque cylinder head bolts after the initial heat cycle if specified. Schedule regular oil and filter changes using the correct viscosity grade oil for your operating environment. Listen for any unusual knocking sounds that may indicate bearing clearance issues, and inspect the oil for metal particles during routine maintenance intervals.
