Clutch Disc 8973771490 8-97377149-0 for ISUZU NKR 4JH1 4HF1 4HG1
Product Overview
The Clutch Disc with OEM numbers 8973771490 / 8-97377149-0 (EXEDY cross-reference ISD086U) is a verified direct-fit replacement for ISUZU NKR / NPR / NQR series light trucks equipped with 4JH1 / 4JH1T / 4HF1 / 4HG1 / 4HG1T engines. This critical component transmits engine power to the transmission for smooth starts and gear shifts.
How It Works
The clutch disc is installed between the engine flywheel and pressure plate, transmitting engine torque through friction contact. When the clutch pedal is depressed, the pressure plate disengages, separating the disc from the flywheel to cut power transmission for gear shifting. This product features a 4-spring damper design to effectively absorb torsional vibrations for smooth power delivery.
Failure Symptoms
Clutch Slippage — Engine RPM rises but vehicle speed does not increase during acceleration
