The wrong undersize on a Cummins main wipes the crank on the first start. Clevite MS-2328H-.026MM is its own size, listed apart from the 0.25 mm set. Mahle's catalog interchange prints older .025 inch undersize numbers as part numbers ending in -.026MM, so do not read this suffix as 0.026 millimeters and do not read it as 0.25 mm.

• Series: H-series is the Clevite tri-metal performance bearing, with medium eccentricity, high crush, and a thin overlay, so the shell stays seated and clears a larger fillet.
• Size: The Mahle size list labels this 0.026MM undersize and lists it next to, not instead of, the 0.25 mm set. In the EB-40-16 interchange, older Clevite suffixes of .025 inch were renumbered to part numbers ending in -.026mm. Measure the journal. Do not grind or assemble to 0.026 mm.
• Part number: Clevite MS-2328H-.026MM.
• Fitment: 5.9 and 6.7 Cummins, 1989-2024, same family as MS-2328H.
• Does not fit: A standard crank, the 0.25 mm set MS-2328H-.25MM, or a 0.50 mm or 0.75 mm P-series set.
• Not in the box: Rod bearings, pistons, and rings are not in this set. Order thrust washers separately if the engine needs them.
