Install Notes
- Measure crankpin journals and verify oil clearance with plastigage or micrometers.
- Standard bearings are for standard-size journals only. If journals are undersize (e.g., -0.25 mm / -0.010”), use the matching undersize bearings.
- Replace bearings as a set during service; do not mix sizes on the same journal.
- Torque connecting rod bolts to spec and use oil or assembly lube as specified by Cummins.
How Many Do I Need?
The inline-6 Cummins has 6 connecting rods (6 rod journals). Each journal uses two bearing shells (upper & lower). For a complete engine refresh you typically need 12 shells total. This item is sold individually; order the quantity you need for your service.

FAQ
Is this a standard (STD) bearing?
Yes. M-4893693 is a standard-size rod bearing for crankshafts within OE specification.
How do I know if I need undersize bearings?
Measure the crankpin journals and compare to Cummins spec. If the crank has been ground undersize, you must use the matching undersize bearings (e.g., -0.25 mm / -0.010”).
Do I need 6 or 12?
You need 12 shells for a full set (two per rod journal). This listing is for individual shells—order the quantity required for your job.
Will this fit both 5.9L and 6.7L?
Yes—this part number covers 2003–2007 5.9L common-rail and 2007.5–2018 6.7L applications. Always verify by ESN.
