Product Description
ISUZU Clutch Disc 5-87610077-0 5876100770 for 4JJ1 4JH1 NKR — 300mm OEM Standard Clutch System Component
ISUZU Clutch Disc 5-87610077-0 5876100770 Compatible with 4JJ1 4JH1 Engine NKR NPR Truck — 300×14mm OEM Standard Replacement
Product Overview
The ISUZU Clutch Disc with OEM numbers 5-87610077-0 / 5876100770 is a precision-engineered replacement designed for ISUZU 4JJ1 and 4JH1 series diesel engines, widely used in NKR and NPR light/medium-duty trucks. This component is a core part of the clutch system — the Clutch Driven Disc Assembly — responsible for smoothly transmitting engine power to the transmission during clutch engagement.
Numbering Note: This product number is 5-87610077-0 / 5876100770. Same series includes 5-87610077-1 / 5876100771 and cross-reference numbers 8-98037004-2 / 8980370042. Please verify the specific number based on actual vehicle configuration.
Working Principle
The clutch disc (driven disc) is a key rotating component of the clutch assembly, installed between the engine flywheel and pressure plate, connected to the transmission input shaft via splines. Its working principle includes:
- Power Transmission: When the driver releases the clutch pedal, the pressure plate clamps the clutch disc against the flywheel, transmitting rotational power through the disc's splined hub to the transmission input shaft.
- Shock Absorption: The disc assembly features a torsional damper (spring system) that absorbs engine torque fluctuations and driveline shock loads, reducing shift shock and driveline vibration.
- Smooth Engagement: Friction material on both sides of the disc ensures smooth engagement with the flywheel and pressure plate, preventing shudder and slippage.
- Power Interruption: When the driver depresses the clutch pedal, the pressure plate separates from the flywheel, interrupting power transmission for gear shifting.
Failure Symptoms
Inspect immediately if any of these occur:
| Symptom | Probable Cause |
|---|---|
| Engine RPM rises but vehicle speed doesn't during acceleration (clutch slipping) | Friction material worn to the limit; insufficient clamping force |
| Severe vehicle shudder during startup | Worn splined hub or failed damper springs |
| Difficulty shifting; gear grinding | Worn clutch disc causing incomplete disengagement |
| Burning smell during driving | Severe clutch disc slippage; friction material overheated |
| Increased pedal travel; higher engagement point | Reduced disc thickness from wear |
