Install Tips
- Measure journal diameter and out-of-round; confirm STD is correct (use plastigauge to verify oil clearance).
- Keep shells and caps paired by cylinder; do not mix upper/lower positions.

FAQ
Is M-4893693 sold as a pair or individually?It’s sold per bearing half. Each connecting rod uses two halves. A 6-cyl engine requires 12 halves for a complete set.
Will this fit both 5.9L (2003–2007) and 6.7L (2007.5–2018)?
Yes—this STD bearing is specified for common-rail cracked-cap rods used in 2003–2007 5.9L ISB and 2007.5–2018 6.7L ISB applications. Verify by ESN and rod style.
What if my crank was ground undersize?
Use an undersize bearing (e.g., .25 mm /.010", .50 mm /.020") to match the regrind. This M-4893693 listing is for STD journals only.
Do these work with non cracked-cap rods?
No—this listing targets cracked-cap common-rail rods. Earlier non cracked-cap rods use different bearings. Check your rod style and ESN before ordering.
How many should I order?
For one engine: order 12 halves (two per rod). If you’re only replacing a damaged journal, order the quantity needed and verify clearance.
