FAQ

Q1: How can I confirm this crankshaft fits my specific Isuzu 4HG1T engine?
A: Please verify the engine code stamped on your engine block. The 4HG1T is a direct fit. Additionally, cross-reference the OEM part number you are replacing (e.g., 8-97033-171-2) with the one listed. If you have the original crankshaft, comparing the main and rod journal diameters is the most accurate confirmation method.

Q2: What other parts should I replace when installing a new crankshaft?
A: It is highly recommended to replace all main bearings, connecting rod bearings, and thrust washers. You should also install a new rear main seal and front oil seal. If the engine has high mileage, consider replacing the oil pump as well to ensure proper lubrication and protect your new investment.

Q3: Does this crankshaft come with the main and rod bearings?
A: No, this listing is for the crankshaft only. Main bearings and connecting rod bearings are sold separately. We recommend purchasing a matched set of bearings to ensure correct oil clearance. Please contact us if you need a complete bearing set.
