5-87818080-3 GASKET SET; ENG OVERHAULfor ISUZU NKR77/4HE1

This ISUZU ENGINE ENG OVERHAUL GASKET SET (Part No.: 5-87818080-3) is designed specifically for ISUZU NKR77 series excavators with 4HE1 engines. It's essential for engine overhaul and sealing, forming a reliable seal at key joints—like cylinder block-head interfaces, oil, and coolant channels. This prevents leakage of oil, coolant, and high-pressure gas, avoiding power loss, overheating, or major failures, ensuring the 4HE1 engine performs optimally post-overhaul and supports long-term stable operation of NKR77 excavators.

As an authorized ISUZU distributor, we ensure this ENG OVERHAUL GASKET SET (Part No.: 5-87818080-3) meets original factory standards. Made from high-grade composite materials, it resists temperatures up to 300℃ and high pressure. Precision stamping and laser cutting guarantee perfect fit with 4HE1 engine parts, eliminating installation modifications. Each set undergoes 3 rounds of simulated NKR77 excavator stress tests to prevent aging and seal failure. This quality reduces maintenance costs and engine damage risks.
