29 Years of One-Stop Full-Range ISUZU Truck Parts Supply

 

Product Overview

 

We are a trusted supplier with 29 years of expertise in full-range ISUZU truck parts. This Alternator Vacuum Pump Oil Pipe is a precision-engineered replacement for ISUZU NHR, NKR55, NKR77, and G5 trucks equipped with 4JB1 / 4JB1-TC engines. It directly replaces OEM parts 8944436449 and 8-94443644-9, ensuring stable oil supply to the alternator-integrated vacuum pump, maintaining proper lubrication, preventing oil leaks, and protecting your vacuum system from premature failure.

 

The 4JB1 engine is widely used in ISUZU NKR trucks and is renowned for its durability and reliability in harsh working environments such as construction sites, logistics transportation, and rural operations. The generator vacuum pump plays a vital role in maintaining the engine's normal operation by providing stable vacuum pressure, and the oil line fitting is the key to ensuring efficient oil supply and circulation-preventing oil leakage, insufficient lubrication, and subsequent damage to the vacuum pump or generator.
