FAQ

Q1: How can I confirm this oil pump fits my equipment?
A1: The most reliable method is to check the OEM part number stamped on your current oil pump (8-94428798-3 or 8-94362923-1). Alternatively, verify that your engine is an Isuzu 4JG1 diesel model. If you are unsure, please provide your engine serial number and equipment model to our sales team for cross-verification.

Q2: What is the recommended installation procedure?
A2: Installation should be performed by a qualified mechanic. Key steps include: draining the engine oil, removing the oil pan, unbolting the old pump, and installing the new one with a new gasket. It is critical to prime the pump (fill it with clean oil) before installation to prevent dry start and ensure immediate oil pressure. Always torque bolts to the manufacturer’s specifications.

Q3: What should I check if my oil pressure is low after installation?
A3: Low oil pressure after installing a new pump can be caused by several factors. First, check that the oil pickup tube screen is not clogged and that the O-ring seal between the pump and the block is properly seated. Second, verify you are using the correct viscosity of engine oil. Finally, inspect the main and rod bearing clearances, as excessive wear can prevent the pump from building adequate pressure.
