Technical Specifications

OEM Cross-Reference

This part is a direct replacement for the OEM bearing identified by the primary part number R408H. Always verify the specific size (STD, 0.25, 0.5) required for your application against the engine’s service manual or crankshaft measurements.

Compatibility

This connecting rod bearing is specifically designed for the Mitsubishi 4D95 series diesel engine. This engine is commonly found in a range of industrial and commercial equipment, including:

• Mitsubishi forklifts and construction machinery
• Industrial generators and power units
• Agricultural equipment and tractors
• Various light commercial vehicles utilizing the 4D95 powerplant

It is crucial to confirm the exact engine model and measure the crankshaft journal before ordering to select the correct bearing size.

FAQ

Q: How do I know which size (STD, 0.25, or 0.5) I need to order?
A: The required bearing size is determined by the condition of your engine’s crankshaft connecting rod journals. The crankshaft must be measured with a micrometer after it is removed and cleaned. If the journals are within standard factory specifications, order STD. If the crankshaft has been machined (“ground”) to repair wear, the machinist will specify the required oversize (e.g., 0.25mm undersize) to match the new bearing.

Q: Is this a genuine OEM Mitsubishi part?
A: This is an OEM-*quality* or OEM-*specification* replacement part. It is manufactured to the exact same design, dimensions, and material specifications as the original Mitsubishi part numbered R408H, making it a fully compatible and reliable alternative for repair and rebuild purposes.

Q: What is the recommended installation procedure for these bearings?
A: Professional installation is critical. Always clean all components thoroughly, use assembly lubricant, and torque the connecting rod bolts to the manufacturer’s specified value and sequence using a calibrated torque wrench. Ensure proper oil clearance is verified via Plastigage or precise micrometers during assembly. Never file or modify the bearing.
