Serial Number Fitment Notice
Main bearing fitment must be confirmed by engine serial number, crankshaft condition, and the exact bearing size required after measurement. 22627434 / 23573151 is the 0.25 mm service-size bearing, so it should not be substituted for standard, 0.07 mm, 0.50 mm, or 0.75 mm bearing kits unless the crankshaft has been measured and specified for that size.
When This Part Needs Replacement
Replace the main bearing kit during an engine rebuild or crankshaft service when bearing wear, scoring, low oil pressure, crankshaft journal damage, excessive clearance, bearing material loss, or lubrication failure has been confirmed. Main bearings should be selected only after the crankshaft journals are inspected and measured.
Installation Notes
Installation should be performed by a qualified engine technician. Crankshaft journal size, bearing clearance, bearing cap location, thrust washer condition, oil passages, and lubrication system cleanliness are critical. Related crank mechanism components to inspect include crankshaft seals, thrust washer kits, big-end bearing kits, connecting rods, cylinder liner kits, piston ring kits, and vibration damper hardware shown in the same crank mechanism group.

Parts Desk Insight
The key detail is the 0.25 mm service size. Main bearing kits must match the crankshaft journal measurement, not just the engine model. Matching the serial number, crank mechanism diagram, and measured bearing size helps ensure the correct bearing set is ordered for the rebuild.
