Clutch Pipe Flex Hose 8-98077611-2 8980776112 For ISUZU 700P 4HK1 Truck Hydraulic Clutch Line

The Clutch Pipe Flex Hose (OEM Numbers: 8-98077611-2 / 8980776112) is a premium-quality, direct replacement hydraulic clutch component designed specifically for ISUZU 700P series trucks equipped with 4HK1 diesel engines. This flexible clutch hose — also known as a clutch hydraulic hose, clutch line, or flex pipe — is a critical part of the hydraulic clutch release system.

It connects the clutch master cylinder to the clutch slave cylinder, transmitting pressurized clutch fluid while accommodating engine and chassis movement. The flexible construction absorbs vibration and allows for slight misalignment between components, ensuring reliable clutch operation under all driving conditions.

Function: The clutch pipe flex hose transfers hydraulic pressure from the clutch master cylinder to the slave cylinder, enabling smooth clutch disengagement and reliable gear shifting in ISUZU 700P trucks.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function.
• High-Strength Construction: Rubber core with synthetic fiber braiding withstands high hydraulic pressures and vibration.
• Corrosion-Resistant Fittings: Metal end fittings resist corrosion and ensure secure, leak-free connections.
• Flexible Design: Accommodates engine and chassis movement without kinking or cracking.
• Restores Clutch Performance: Eliminates spongy pedal, fluid leaks, and shifting difficulty caused by a worn or damaged hose.
• Direct Replacement: Matches OE hose dimensions, routing, and connection points for simple installation.
• Long Service Life: Engineered for medium-duty commercial truck applications.
• Essential Hydraulic Component: Critical for reliable clutch operation and driver control.
• Cost-Effective Repair: Affordable replacement that prevents costly clutch system damage.

This clutch pipe flex hose is specifically designed for ISUZU medium-duty trucks and commercial vehicles. Common applications include:

• ISUZU 700P (Medium-Duty Trucks)
• ISUZU N Series (NK, NM — as applicable)
• ISUZU 4HK1 Engine Specifications:
  • 4-Cylinder, Inline Turbo Diesel
  • Displacement: 5.2L
  • Application: Medium-duty trucks and commercial vehicles
• Also compatible with various ISUZU models using the 4HK1 engine and the same clutch hydraulic system configuration.

Professional mechanic installation is recommended. Follow these steps:

1. Ensure vehicle is safely parked — Apply parking brake and chock wheels.
2. Disconnect battery — Always disconnect the negative terminal before working.
3. Locate the clutch flex hose — Identify the hose connecting the clutch master cylinder to the slave cylinder.
4. Remove old hose — Disconnect the fittings at both ends; cap the lines to prevent fluid loss and contamination.
5. Inspect related components — Check the master cylinder, slave cylinder, and other hydraulic lines for wear or damage; replace if necessary.
6. Clean connections — Remove dirt, grease, and debris from the fitting threads and mounting points.
7. Install new hose — Position the new clutch pipe flex hose in the correct routing; hand-start the fittings at both ends.
8. Torque fittings — Tighten all connections to manufacturer torque specifications. Do not over-tighten.
9. Bleed the clutch system — Bleed the hydraulic system to remove air; use the correct procedure and fluid.
10. Check fluid level — Top up the clutch master cylinder reservoir with the correct fluid.
11. Check for leaks — Inspect all connections for fluid leaks; ensure the hose is not kinked or rubbing against other components.
12. Test clutch operation — Depress the clutch pedal; verify smooth operation and proper pedal feel.
13. Road test — Test drive to verify proper clutch disengagement and gear shifting.
