Mercedes Sprinter Connecting Rod Bearing Set 0.50mm Oversize – Kolbenschmidt | NCV3 3.0L OM642 | #6420300260050 (2007–2022)

When the OM642's rod journals require removal beyond what a 0.25mm grind can address, the journals must be precision-ground to 0.50mm undersize and the matching oversize shells installed. This is the Kolbenschmidt connecting rod bearing set in 0.50mm oversize for NCV3 and VS30 Sprinters equipped with the 3.0L OM642 V6, for use after crankshaft rod journals have been precision-ground 0.50mm undersize.

What This Part Does

The 0.50mm oversize rod bearing shells compensate for the deeper grind required on journals with severe scoring or out-of-round wear that could not be corrected at 0.25mm undersize. These are the maximum standard grind option for OM642 rod journals. If journals cannot be restored to a true surface at 0.50mm undersize, crankshaft replacement is required.

When to Use

Use only after crankshaft rod journals have been precision-ground 0.50mm undersize. Always confirm journal diameter with a micrometer and verify clearances with plastigauge before final assembly.
