Clutch Slave Cylinder 8-98089676-0 8-97148628-2 For ISUZU NPR 700P 4HK1 Engine 8980896760 8971486282

The Clutch Slave Cylinder (OEM Numbers: 8-98089676-0 / 8-97148628-2 / 8980896760 / 8971486282) is a premium-quality, direct replacement hydraulic clutch component designed specifically for ISUZU NPR and 700P series trucks equipped with 4HK1 diesel engines. This precision-engineered cylinder is a critical part of the hydraulic clutch release system — it receives pressurized clutch fluid from the clutch master cylinder via the hydraulic line and converts it into mechanical movement that actuates the clutch release fork, disengaging the clutch for smooth gear changes.

Function: The clutch slave cylinder converts hydraulic pressure from the clutch master cylinder into mechanical force to disengage the clutch, enabling smooth gear changes in ISUZU NPR and 700P 4HK1 diesel trucks.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• Precision-Honed Bore: Smooth, accurate bore ensures consistent piston movement and reliable hydraulic pressure transmission.
• Durable Seals: High-quality piston seals resist wear, heat, and clutch fluid degradation.
• Smooth Clutch Operation: Provides consistent clutch pedal feel and smooth engagement/disengagement.
• Leak-Proof Design: Precision machining and quality seals prevent fluid leaks and system pressure loss.
• Prevents Shifting Issues: Restores proper clutch disengagement — eliminates grinding gears and hard shifting.
• Direct Replacement: Matches OE cylinder dimensions, mounting points, and hydraulic connections.
• Complete Assembly: Includes push rod and mounting hardware where applicable.
• Restores Drivability: Ensures safe and reliable clutch operation in commercial truck applications.

• Valvetrain: OHV
• Application: Medium-duty trucks and commercial vehicles

Professional mechanic installation recommended:

1. Locate the slave cylinder — Typically mounted on the transmission bell housing.
2. Disconnect the hydraulic line — Carefully disconnect the hydraulic fluid line from the slave cylinder.
3. Remove the push rod — Disconnect the push rod from the clutch release fork.
4. Remove mounting bolts — Unbolt the old slave cylinder from the transmission.
5. Inspect the release fork — Check the clutch release fork for wear or damage.
6. Clean the mounting surface — Clean the mounting area on the transmission.
7. Install the new cylinder — Position the new slave cylinder and hand-start mounting bolts.
8. Torque bolts — Tighten mounting bolts to manufacturer torque specifications.
9. Connect the push rod — Attach the push rod to the clutch release fork.
10. Connect the hydraulic line — Reconnect the hydraulic fluid line; use new sealing washers if applicable.
11. Bleed the clutch system — Bleed the hydraulic system to remove air; use the correct procedure and fluid.
12. Check fluid level — Top up the clutch master cylinder reservoir with the correct fluid.
13. Test clutch operation — Depress the clutch pedal; check for smooth operation and correct pedal feel.
14. Inspect for leaks — Check all connections for fluid leaks.
15. Adjust if necessary — Adjust push rod length or free play if required per manufacturer specifications.
