ISUZU Clutch Slave Cylinder 8-97032847-1 8970328471 for NPR66 4HF1 — 25.4mm OEM Standard
Product Overview
The ISUZU Clutch Slave Cylinder Assembly with OEM numbers 8-97032847-1 / 8970328471 is a precision-engineered replacement designed for ISUZU NPR66 series trucks, compatible with 4HF1 diesel engines. This component is a core actuation element of the clutch hydraulic system, responsible for converting hydraulic pressure from the master cylinder into mechanical force to push the clutch release fork.
Numbering Note: This product number is 8-97032847-1 / 8970328471. The same series also includes 8-97032847-0 / 8970328470 for the same appliions.
Working Principle
The clutch slave cylinder is an actuation component of the clutch hydraulic system, mounted on the transmission housing and connected to the master cylinder via hydraulic lines.
Hydraulic Transmission: When the driver depresses the clutch pedal, the master cylinder converts pedal force into hydraulic pressure transmitted to the slave cylinder.
Piston Actuation: Hydraulic pressure pushes the piston inside the slave cylinder outward, moving the push rod to actuate the release fork.
Clutch Disengagement: The release fork pushes the release bearing to separate the pressure plate from the clutch disc, interrupting power transmission for gear shifting.
Return Process: When the driver releases the clutch pedal, hydraulic pressure is released and the piston returns under spring force, re-engaging the clutch.
Failure Symptoms
Inspect immediately if any of these symptoms occur:
Symptom
Probable Cause
Difficulty shifting gears, especially reverse or first gear
Data Source Note: Bore size, weight, and HS code data are based on IZUMI brand publicly available product information and general industry standards. Test reports available upon request.

Important Fitment Warnings
Number Confirmation: This product number is 8-97032847-1 / 8970328471. Same series also includes 8-97032847-0 / 8970328470. Verify the specific number on the original part before ordering.
Associated Components: When replacing the slave cylinder, it is recommended to inspect the master cylinder as both often fail around the same time.
Brake Fluid Replacement: Replace brake fluid (DOT 3 or DOT 4) and bleed the hydraulic system when replacing the slave cylinder.
Installation Torque: Refer to ISUZU factory workshop manual for slave cylinder mounting bolt and hydraulic line torque specifiions.
Push Rod Inspection: Inspect the push rod for wear before installation and replace if necessary.
Professional Installation: The clutch slave cylinder is a critical clutch system component — professional installation is strongly recommended.
