FAQ

1. How do I determine if I need STD, 0.25, or 0.50 size bearings?

You must measure the crankshaft journal diameter. If the journal is within factory specifications, use STD bearings. If the crankshaft has been reground, the machinist will specify the undersize required (0.25mm or 0.50mm). It is critical to match the bearing size to the journal dimension to maintain correct oil clearance. If you are unsure, consult with a professional engine rebuilder.

2. Can I use these bearings in an Isuzu 4HK1 engine?

No. These bearings are specifically designed for the Isuzu 6HK1 engine (6-cylinder). The 4HK1 is a different engine family with different journal diameters and bearing specifications. Using these bearings in a 4HK1 could result in incorrect oil clearance, leading to engine damage. Always verify your engine model before purchase.

3. What is included in this set?

This set includes all necessary connecting rod bearings (part numbers 1830505c1 / 1830269c1) and main bearings (part number 1817021c1) for a complete engine rebuild on a 6HK1 engine. The quantity of each bearing shell will correspond to the number of cylinders and main bearing journals (6 rod bearings and 7 main bearings typically). Please confirm the exact shell count with your supplier if you require a specific breakdown.
