FAQ

Q: How do I confirm these bearings will fit my 6HK1 engine?
A: While this listing covers the 6HK1 model, bearings can vary by engine serial number and journal size. We recommend removing your old bearing and checking the stamp on the back for the exact part number (e.g., standard or undersize). You can then compare this to the item you receive.

Q: What is the difference between a connecting rod bearing and a main bearing?
A: Connecting rod bearings are installed between the connecting rod and the crankshaft journal, handling the piston’s up-and-down motion. Main bearings support the crankshaft itself within the engine block. Both are critical for smooth rotation and must be replaced together during a major overhaul.

Q: Do I need special tools to install these bearings?
A: Proper installation requires engine rebuilding tools such as a torque wrench, plastigauge (to check oil clearance), and a micrometer. We recommend installation by a qualified diesel mechanic. If you require technical guidance, we offer video support after purchase to assist with fitment questions.
