FAQ

Q1: Is this main bearing set a direct replacement for the original Mitsubishi ME994204?

Yes, this is a direct replacement part. It is manufactured to match the exact dimensions and material specifications of the OEM part number ME994204. It is a standard size (STD), meaning it is intended for use with a standard crankshaft journal that has not been reground.

Q2: Do I need to replace the thrust washers when installing these main bearings?

It is highly recommended. The main bearing set typically includes the upper and lower bearing shells. The thrust washers (often part number ME994205) that control crankshaft end-play should be inspected and replaced simultaneously to ensure proper engine assembly and prevent premature wear.

Q3: What is the recommended installation procedure for these bearings?

Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the bearing saddle and cap. 2) Applying clean engine oil to the bearing surface. 3) Ensuring the bearing locating tab aligns with the notch in the block. 4) Torquing the main bearing cap bolts to the manufacturer’s specific specifications using a calibrated torque wrench. Always check the bearing clearance with Plastigauge.
