8981148001 Original 4HK1 Engine Pump to Gasket

The original Isuzu engine pump gasket (part number: 8981148001) is a sealing component designed specifically for Isuzu 4HK1 series diesel engines, mainly used for sealing between various pumps (such as fuel pumps, oil pumps, or water pumps) on the engine and the engine body. This part number is the original Isuzu accessory identification code. According to the widespread application of Isuzu 6BG1 engine in the field of construction machinery, this gasket is mainly suitable for Hitachi ZX series excavators equipped with this engine, including ZX200-3G, ZX210, ZX230, ZX270 and other models.

As an original sealing component, the core function of this gasket is to form a reliable seal between the pump body and the engine mounting surface, preventing oil, fuel, or coolant leakage. It is usually made of multi-layer composite materials, with a common structure consisting of a metal skeleton (such as steel or copper sheets) and an elastic material that is resistant to oil and high temperature (such as rubber, graphite, or asbestos), combining the strength of the metal with the sealing properties of the elastic material. Its design strictly matches the installation surface shape, bolt hole position, and flow channel opening of the original pump, ensuring even compression and tight sealing after installation.
 

The maintenance core of this gasket lies in regular inspection, standardized replacement, and clean installation. Regular inspection: It is recommended to check for oil stains, water stains, or fuel leakage around the joint surface between the pump body and the engine every 500 working hours or during monthly maintenance. This is a clear indication of gasket failure. Timing of replacement: Gaskets are disposable seals and must be replaced with new gaskets during any maintenance work involving pump disassembly (such as replacing pump assemblies or major engine repairs). Reusing is strictly prohibited.
