FAQ

Q1: How do I confirm if this 0.25mm undersize bearing is correct for my engine?
A1: The 0.25mm undersize is used when the engine crankshaft journals have been machined (ground) to this specific undersize during a rebuild. You must measure your crankshaft journals with a micrometer or refer to the machine shop’s work order to confirm the required undersize (e.g., 0.25mm, 0.50mm) before ordering.

Q2: Are the main bearings and connecting rod bearings sold together or separately?
A2: This listing is for a complete set that includes both the main bearings (which support the crankshaft in the engine block) and the connecting rod bearings (which connect the rods to the crankshaft). They are sold as one complete kit for a full engine bearing service.

Q3: What installation precautions should be taken with these bearings?
A3> Ensure the engine block, crankshaft, and connecting rods are meticulously clean. Verify all oil passages are clear. Use assembly lubricant during installation. Always torque the main cap and conrod bolts to the manufacturer’s specified sequence and torque values using a calibrated torque wrench. Proper installation is critical for bearing life and engine performance.
