Thumbnail Filmstrip of 3.9L Cummins P-Series Main Bearing Set (Standard) Clevite MS-1718P Images
Wiped mains in a 4BT knock and drop oil pressure in a four-cylinder block. Clevite MS-1718P is the P-series main set for a 3.9L 4BT. It fits 1989-1998.
- Series: P-series is the Clevite tri-metal bearing, steel-backed with a copper-lead overlay, and it is the replacement shell rather than the H-series piece.
- Size: Standard size, for a main journal that has not been ground undersize. An undersize journal will be too loose on this shell.
- Part number: Clevite MS-1718P. OE numbers include 3802010.
- Fitment: 3.9 Cummins 4BT, 1989-1998.
- Does not fit: A 5.9 or 6.7, which uses MS-2328. Do not use it on a 4.5L unless you confirm the crank.
- Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.
