FAQ

Q1: Will this bearing set fit my Mitsubishi L3E engine if it has been previously ground?
A: This set is for standard (STD) journal sizes. If your crankshaft has been machined to an undersize (e.g., 0.25mm or 0.50mm), you will require the corresponding undersize bearing set. Please check the journal diameter before ordering.

Q2: Can I install these bearings without professional tools?
A: While DIY installation is possible, we recommend professional installation by a certified diesel mechanic. Proper oil clearance must be verified using Plastigage to prevent engine seizure or low oil pressure.

Q3: Are these bearings specific to the main caps or connecting rods?
A: This set includes both. However, main bearings and rod bearings have different widths and oil grooves. Ensure you match the correct bearing to the corresponding cap (main cap vs. rod cap) during installation.
