FAQ

Q1: Is this bearing set the correct STD size for my Mercedes C240 engine rebuild?
A1: Yes, the M4525 is manufactured to the original Standard (STD) specification for the crankshaft journals. It is crucial to measure your crankshaft for wear before installation. If the crankshaft has been machined (ground), you will require undersize bearings (e.g., .010″, .020″).

Q2: What is included in the “set”?
A2: A complete main bearing set typically includes all upper and lower bearing shells required for one engine. Please confirm the exact quantity with your order, as sets can vary (e.g., 5 pairs for a 5-cylinder engine).
