FAQ

Q1: Is this bearing set suitable for both standard and rebuilt crankshafts?
A1: This set is typically for standard-size journals. If your crankshaft has been machined (ground), you will need corresponding undersize bearings (e.g., 0.25mm, 0.50mm). Always measure your crankshaft main journal diameters before purchase.

Q2: Does the kit include all required bearings for a complete engine rebuild?
A2: The M177H1 kit is a complete main bearing set, including all upper and lower shells for the crankshaft main journals. For a full rebuild, connecting rod bearings and other components must be sourced separately.

Q3: What is the recommended installation procedure?
A3: Always follow the engine manufacturer’s service manual. Key steps include: thoroughly cleaning the engine block and crankshaft saddles, verifying correct bearing clearance with Plastigage, ensuring proper oil passage alignment, and torquing main cap bolts to the specified sequence and value with a calibrated torque wrench.
