• Size: Standard

Fitment

Mercedes catalogue references in the A27003302xx family identify individual main-bearing shells selected by position and colour grade; they do not prove that every M270 or M274 uses one universal set. Confirm the exact engine code, crankshaft journal measurements, housing bore, bearing width, oil-hole arrangement and required grade. Standard-size bearings are only suitable when the crankshaft remains within factory standard journal specifications.

Installation

Engine rebuilding must be completed by a qualified automotive machinist or engine builder. Verify oil clearances with precision measuring equipment, observe bearing orientation and torque specifications, lubricate correctly and confirm free crankshaft rotation before assembly.
