ISUZU 8-97089652-0 Clutch Release Bearing Pre-Lubricated Sealed Ball Bearing OEM Standard for NPR66 4HF1 Truck

A pre-lubricated, sealed ball bearing that mounts on the clutch release fork. When the clutch pedal is depressed, it applies pressure to the pressure plate diaphragm spring, disengaging the clutch for smooth, noiseless gear changes.

The Clutch Release Bearing (OEM Numbers: 8-97089652-0 / 8970896520), also known as a throw-out bearing, is a premium-quality, direct replacement component engineered specifically for ISUZU NPR66 series medium-duty trucks powered by the 4HF1 4.3L diesel engine.
