FAQ

Q1: How do I confirm this is the correct bearing set for my S6D125 engine?
A1: The most reliable method is to cross-reference the part numbers stamped on your old bearings or listed in your engine’s service manual with our primary part number 6150-21-8010 and rod bearing number TW-2612K. Also, verify your crankshaft journal size (Standard or Undersize) is correct.

Q2: What is the recommended procedure for installing these bearings?
A2: Professional installation is crucial. Always clean all engine surfaces thoroughly, use assembly lubricant, and torque the main and rod caps to the manufacturer’s specified sequence and values. Proper oil clearance must be checked with Plastigage or micrometers during assembly.

Q3: Do you supply bearings for other sizes (oversize/undersize) for reground crankshafts?
A3: Yes. While this listing is for the Standard (STD) size, we typically stock a full range of oversizes (e.g., 0.25mm, 0.50mm). Please contact our sales team with your specific requirements for reground crankshaft journals.
