8-98091566-0 BUSHING; DRIVE SHAFT,OIL PUMP ISUZU for ZX200-3/4HK1

Precision Support for Oil Pump Driveshaft Alignment

This bushing provides a precision bearing surface for the oil pump drive shaft, ensuring smooth rotation and accurate alignment within the oil pump housing. Isuzu Genuine Bushings are manufactured to exact OEM specifications for inner diameter, outer diameter, and surface finish, maintaining the critical clearance required for consistent oil pressure and reliable pump operation. Aftermarket bushings with incorrect dimensions can cause shaft misalignment, accelerated wear, and oil pressure fluctuations. Used in Isuzu 4HK1, 4HF1, 4HG1, 4JJ1, and 6HK1 engine families found in NPR/NQR/NRR trucks and Hitachi excavators, with common part numbers including 8-94393-596-1, 8-94393-596-0, and 8980915660.

Durable Construction for Continuous Lubrication Service

Subjected to continuous shaft rotation, oil pressure, and sustained engine vibration, the bushing must resist wear, scoring, and deformation over the engine's life. Isuzu Genuine Bushings are constructed from high-grade wear-resistant materials to withstand harsh oil conditions and maintain correct shaft clearance. The bushing is a critical component in the oil pump assembly, ensuring the drive shaft remains properly centered for efficient oil delivery to the engine's lubrication system.
