Technical Specifications

OEM Cross-Reference

This piston ring set is a direct replacement for the following OEM part numbers:

• SDI10177ZZ (Original Isuzu/NPR Reference)

Note: Always verify your existing part number against the SDI10177ZZ reference. While this is the primary OEM number for the 4HE1 engine, cross-referencing with your engine’s serial number is recommended for absolute confirmation.

Compatibility

This piston ring set is specifically designed for the Isuzu 4HE1 diesel engine. It is commonly used for the following applications:

• Excavators: Isuzu-powered mini and mid-size excavators (e.g., models using the 4HE1 engine).
• Trucks: Isuzu Elf, Forward, and other medium-duty trucks from the 1993-2003 era.
• Industrial Equipment: Generators, pumps, and other machinery powered by the Isuzu 4HE1 engine.

Important Fitment Note: The 4HE1 engine was widely used in various chassis and equipment models. While this ring set is a mechanical fit for the engine block, we recommend confirming your engine’s specific model code (e.g., 4HE1-TC, 4HE1-X) and year of manufacture to ensure compatibility with your specific application.

FAQ

Q1: How do I confirm that this piston ring set (SDI10177ZZ) will fit my Isuzu 4HE1 engine?

A: First, check the part number on your old piston ring set. It should match SDI10177ZZ. Second, measure the cylinder bore diameter; it must be 110mm. Finally, verify your engine model code (e.g., 4HE1) stamped on the engine block. If all three match, this set is the correct replacement.

Q2: What is included in this piston ring set, and is it complete for one cylinder?

A: This set includes all the necessary rings for a single cylinder: typically one top compression ring, one second compression ring, and one oil control ring assembly. For a complete engine rebuild, you will need to purchase one set per cylinder (e.g., 4 sets for a 4-cylinder 4HE1 engine).

Q3: Do you provide installation instructions or technical support for this product?

A: While specific installation manuals are not included, we offer video technical support to assist with common installation questions. We strongly recommend that installation be performed by a qualified diesel mechanic who is familiar with Isuzu 4HE1 engine specifications to ensure proper ring gap and orientation.
