Clutch Disc 8-98164918-0 for ISUZU NPR 4HE1-TC

Heavy Duty 325mm 21-Spline Truck Clutch Disc — OEM: 8981649180, 5876101050

Product Overview

The Clutch Disc (Clutch Plate) with OEM numbers 8-98164918-0 and 5-87610105-0 is a verified direct-fit replacement for ISUZU NPR (NPR 4.8L, NPR HD), NQR, and 700P series medium-duty trucks equipped with the 4HE1-TC (4HE1T) 4.8L turbo-diesel engine or 4HK1 engine, paired with the MZZ6U manual transmission.

This heavy-duty disc is specifically engineered for the 350–430 Nm (258–317 lb-ft) of torque produced by the 4HE1-TC engine, ensuring reliable torque transfer, shock absorption, and smooth engagement under heavy commercial vehicle loads.

Technical Specifications

Part Number:	8-98164918-0 8981649180 5876101050	Product Name:	Clutch Disc
Car Model:	ISUZU NPR	Engine Model:	ISUZU 4HE1-TC
Condition:	100% Brand New	Quality Standard:	OEM equivalent / ISO quality control

Features & Benefits

Precision-engineered 325mm diameter
Full friction surface contact with 4HE1 flywheel — maximizes torque transfer capacity (handles 430 Nm/317 lb-ft safely).

21-tooth splined hub
Eliminates driveline backlash and noise — ensures smooth engagement with MZZ6U transmission input shaft.

High-grade composite facing
Superior heat dissipation and wear resistance — longer service life under heavy-duty truck operation.

10-torsion spring damper hub
Superior vibration damping — absorbs 4-cylinder diesel engine pulsations and driveline shock.

Heat-treated rivets
Positive facing retention — prevents facing separation under high torque loads in severe-duty applications.

IATF 16949 certified manufacturing
Consistent OEM-level quality — produced under internationally recognized automotive quality standards.

Common Failure Indicators

Clutch slipping — Engine RPM rises but vehicle speed does not increase proportionally, especially under load
Clutch judder / chatter — Vibration or jerking during clutch engagement from a stop
Difficulty shifting gears — Incomplete clutch disengagement due to worn or warped disc
Squealing or grinding noise — When depressing the clutch pedal, indicating facing wear down to the rivets
Oil or grease contamination — If seals leak, fluid can soak the facing, causing slippage
High mileage (>200,000 km) — Preventive replacement during clutch system overhaul

Installation Requirements

⚠️ IMPORTANT: Clutch disc replacement on ISUZU NPR 4HE1-TC requires transmission removal and specialized tools. Professional installation by qualified mechanics strongly recommended.

Critical Tools Required:

Transmission jack (adequate capacity for NPR's heavy transmission)
Torque wrench (5–200 Nm range)
Clutch alignment tool with 21-tooth spline — critical for centering the disc
Flywheel resurfacing equipment (optional, by machine shop)

Recommended Replacement Components: Always replace clutch disc + pressure plate + release bearing together for optimal service life.

Quality Assurance

Manufactured in IATF 16949 certified facilities, ensuring consistent OEM-level quality and compliance with rigorous automotive industry requirements.

QC Item	Verification Method
Facing friction coefficient	SAE J661 standard dynamometer test
Spline dimensional accuracy	CMM inspection against OE blueprint
Spring load rate	Spring dynamometer compression testing
Parallelism and runout	Dial gauge measurement (runout ≤0.15 mm)
Thermal cycle endurance	500 cycles from ambient to 300°C facing temperature

Packaging & Supply

Individually sealed in anti-rust VCI paper and protective plastic bag
Packed in heavy-duty foam-lined carton for freight protection
Bulk wholesale: 20–50 discs per master carton with dividers
