FAQ

Q1: How do I identify the correct bearing size for my 4HK1 or 6HK1 engine?
A: Always check the stamping on the back of your original bearing or the engine block. This kit is for standard (STD) size. If your crankshaft has been ground, you will need an undersized bearing (e.g., 0.25mm or 0.50mm). We recommend inspecting the crankshaft journal condition before ordering.

Q2: Are these bearings installed with any special lubricant?
A: Yes, during installation, apply a thin layer of clean engine oil or assembly lube to the bearing surface and the back of the shell. Never use grease. Proper lubrication prevents scuffing during the initial engine startup.

Q3: What is the typical installation torque for connecting rod and main bearing caps on these Isuzu engines?
A: Torque specifications vary by engine model and year. For 4HK1 and 6HK1 engines, main bearing cap bolts are typically torqued to approximately 165-175 Nm (122-129 ft-lb) and connecting rod bolts to 80-90 Nm (59-66 ft-lb). Always consult a factory service manual for your specific engine serial number for exact torque angles and sequences.
