4HG1 Piston With Pin 8972214840 8-97221484-0 8-97221-484-0 Isuzu Engine Parts

Product Details

Product Overview

This high-quality 4HG1 Piston with Pin is a direct replacement component designed for Isuzu diesel engines. Referencing the critical OEM numbers 8972214840, 8-97221484-0, and 8-97221-484-0, this piston assembly ensures precise fitment and reliable performance for your heavy-duty machinery.

The piston is a core component of the engine’s combustion system, converting the force of expanding gas into mechanical energy. This specific unit is manufactured to OEM size specifications, making it suitable for a wide range of industrial applications, including construction equipment, agricultural machinery, generators, and marine engines. While fitment is commonly inferred for the Isuzu 4HG1 engine platform, we recommend verifying your engine’s serial number and existing part numbers for absolute compatibility.

FAQ

Q: How do I confirm this piston will fit my engine?
A: First, verify your engine model number (e.g., 4HG1) and the part number on your current piston. If it matches any of the OEM numbers listed (8972214840, 8-97221484-0, or 8-97221-484-0), it is the correct replacement. If you are unsure, contact our support team with your engine serial number for verification.

Q: Does this piston come with the rings and pin?
A: This specific product listing is for the Piston with Pin. It includes the piston body and the wrist pin. Please check the product specifications carefully. Piston rings are typically sold separately to allow you to select the correct ring set for your application.

Q: What is the standard maintenance for a 4HG1 piston during an engine rebuild?
A: When rebuilding a 4HG1 engine, it is critical to measure the cylinder bore for wear and out-of-roundness. If the bore is within spec, a standard-size piston like this one can be used with new rings. Always lubricate the piston pin, rod bushing, and cylinder walls with clean engine oil during assembly. We recommend following the official Isuzu service manual for torque specs and installation procedures.
