FAQ
Q1: How do I know if I need a 0.25mm undersize bearing?
A1: Undersize bearings are required when the engine crankshaft journals have been machined (or “ground”) to remove scoring or out-of-roundness. The machinist will measure the journals after grinding to determine the correct undersize (e.g., 0.25mm, 0.50mm) needed to restore the proper clearance. Always follow the machine shop’s specifications.
Q2: Is this a complete set for a full engine rebuild?
A2> This product is specifically the main bearing and connecting rod bearing set. A complete engine overhaul typically requires additional components such as piston rings, gasket kits, seals, and often other wear items. We recommend purchasing a comprehensive rebuild kit or consulting our parts catalog for all necessary components.
Q3: What is the recommended installation procedure?
A3: Professional installation is crucial. Key steps include: thoroughly cleaning all engine passages, verifying bearing clearances with Plastigage or micrometers as per service manual specifications, ensuring proper lubrication during assembly, and following the manufacturer’s torque sequence and values for the bearing caps. Incorrect installation can lead to immediate engine failure.
