FAQ

Q1: How do I confirm if I need the 0.50mm undersize bearings?
A: The 0.50mm undersize is used when the engine’s crankshaft journals have been machined (ground) to repair wear or damage. You must measure the journals with a micrometer or refer to the machine shop’s work order that performed the crankshaft grinding to determine the correct undersize required (e.g., 0.25mm, 0.50mm, 0.75mm). Using the wrong size will result in incorrect oil clearance and potential engine failure.

Q2: Is this a complete set for one engine?
A: Yes, this listing is for a complete bearing set, including all required main bearings and connecting rod bearings for one Isuzu 4HG1T engine at the 0.50mm undersize. Always install bearings as a complete set to ensure uniform performance and oil clearance across all journals.

Q3: What are the installation torque specifications for these bearings?
A: Critical torque specifications are determined by the engine’s connecting rod bolts and main bearing cap bolts, not the bearings themselves. You must always refer to the official Isuzu 4HG1T engine service manual for the correct bolt torque sequence, torque value, and any required angle-tightening procedures. Using improper torque can lead to bearing failure or catastrophic engine damage.
