FAQ

Q: How can I confirm this connecting rod fits my Mitsubishi K4N engine?
A: First, locate the existing connecting rod part number on your engine or in your service manual. Compare it with the OEM numbers listed (30h19-00030 or 30h19-00031). Additionally, verify your engine model number (K4N or K4M) stamped on the engine data plate. If uncertain, provide us with your engine serial number and equipment make/model for cross-reference assistance.

Q: What is the recommended installation procedure for this connecting rod?
A: Installation should be performed by a qualified diesel mechanic following the Mitsubishi factory service manual. Key steps include: cleaning the rod and cap mating surfaces, applying proper torque to connecting rod bolts (using a torque wrench in the specified sequence), checking bearing clearance with plastigage, and ensuring correct piston pin fit. Always replace connecting rod bolts with new ones as recommended by the engine manufacturer.

Q: Can this connecting rod be used in high-performance or turbocharged K4M engines?
A: This connecting rod is manufactured to OEM specifications suitable for standard-duty applications. For turbocharged or high-performance engines, we recommend consulting with our technical team to verify if this rod meets the increased stress requirements. In some cases, upgraded connecting rods with enhanced material properties may be recommended for modified or heavily loaded engines.
