ISUZU 4KH1 Clutch Disc 5-87610083-0 8-98080661-0 OEM Fit 24T Spline 250mm Outer Diameter BVP Clutch Friction Disc

The Clutch Disc with OEM numbers 5-87610083-0 and 8-98080661-0 is a verified direct-fit replacement for ISUZU 100P-T / 600P / NHR / NKR / NMR / TFR / TFS / D-MAX series light and medium-duty trucks equipped with 4KH1 / 4JB1T / 4JB1 / 4JG2 / 4JH1 diesel engines. This clutch disc is a critical component of the manual transmission clutch system, responsible for transmitting engine torque to the transmission while allowing smooth engagement and disengagement of the drivetrain.

This product is part of the ISUZU BVP (Best Value Parts) series — maintenance-specific parts launched by ISUZU for ISUZU vehicles. BVP advantages include:

• Significantly lower price than imported genuine parts.
• Manufactured to ISUZU's technical quality standards with the same quality management as Japan ISUZU.
• Produced by ISUZU's Chinese OEM suppliers or strictly designated manufacturers.
• Affixed with ISUZU anti- labels to prevent forgery.

The clutch disc is positioned between the engine flywheel and the clutch pressure plate. It features a friction material facing on both sides that grips the flywheel and pressure plate surfaces when the clutch is engaged. The disc's torsional damper springs absorb engine torque fluctuations and dampen drivetrain vibration, ensuring smooth power delivery and protecting the transmission from shock loads. The disc is mounted on the transmission input shaft via a 24-tooth splined hub, allowing it to slide axially for engagement and disengagement while transmitting rotational torque. The 4KH1 is a 3.0L inline-four diesel engine and the 4JB1T is a 2.8L turbo-diesel, both widely used in ISUZU 100P-T / 600P series trucks.

Replace the clutch disc when any of these symptoms appear:

• Clutch slipping under acceleration — a worn friction facing cannot transmit full engine torque, causing engine RPM to rise without corresponding vehicle speed increase.
• Difficulty engaging or disengaging gears — a damaged or warped disc prevents smooth clutch operation.
• Chattering or shuddering during clutch engagement — worn damper springs or contaminated friction facing cause vibration during engagement.
• Burning smell from the clutch area — severe slipping produces a characteristic burning odor from the friction material.
• Clutch pedal vibration or pulsation — a warped or imbalanced disc transmits vibration through the pedal.
• Metal debris in the clutch housing — rivet or spline wear produces metal particles that contaminate the clutch assembly.

1. Preparation: Disconnect the battery negative terminal. Raise the vehicle on a hoist. Remove the transmission from the engine.
2. Removal: Remove the clutch cover bolts in a diagonal sequence. Remove the pressure plate and clutch disc. Inspect the flywheel surface for cracks, heat spots, or scoring.
3. Inspection: Inspect the flywheel for flatness and surface condition. Resurface or replace if any abnormality is found. Inspect the transmission input shaft splines for wear.
4. Preparation for New Clutch: Clean the flywheel surface with brake cleaner. Apply a thin coat of high-temperature grease to the transmission input shaft splines.
5. Installation: Position the new clutch disc on the flywheel with the alignment tool inserted through the disc hub. Install the pressure plate and hand-tighten the bolts. Tighten the clutch cover bolts to specification in a diagonal sequence.
6. Transmission Installation: Remove the alignment tool. Carefully install the transmission onto the engine, ensuring the input shaft splines engage the clutch disc hub.
7. Final Check: Verify the clutch pedal free play is within specification. Check the clutch release bearing operation.
8. Road Test: Perform a road test to verify smooth clutch engagement and disengagement.

• Every 10,000 km: Check clutch pedal free play. Inspect for clutch slipping or chattering.
• Every 40,000–50,000 km: Inspect clutch operation. Check for abnormal noise or vibration.
• When clutch slipping is detected: Inspect clutch disc immediately. Replace if friction facing is worn.
• At clutch replacement: Always replace the disc, pressure plate, and release bearing as a complete kit.
