Good To Know

Q: Do I need to replace all main bearings at once? A: It is common practice to replace the full set during a crankshaft rebuild, so confirm the count for your engine before ordering. Q: Can I install this without checking clearances? A: No, measure oil clearance with plastigauge and compare against your service manual before final assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
