Product Description
ISUZU Clutch Release Bearing 1-09820115-0 1098201150 for NPR 4BG1
ISUZU Genuine Clutch Release Bearing 1-09820115-0 1098201150 Compatible with NPR 4BG1 Engine — OEM Quality Clutch Release System Component
Product Overview
The ISUZU Clutch Release Bearing with OEM numbers 1-09820115-0 / 1098201150 is a genuine OEM replacement designed for ISUZU NPR series trucks, compatible with 4BG1 diesel engines. This component is a core actuation element of the clutch system, responsible for pushing the clutch pressure plate diaphragm spring when the driver depresses the clutch pedal, enabling smooth disengagement and engagement of engine power to the transmission.
Numbering Note: This product number is 1-09820115-0 / 1098201150. Reference numbers include 1-09820-115-0, 109820-1150. The same series also includes 1-09820078-0 / 1098200780. This is a Genuine Isuzu Part, exactly the same as the one mounted at the factory when the vehicle was new.
Working Principle
The clutch release bearing (also known as "throw-out bearing") is a key component of the clutch actuation mechanism, installed on the release fork at the front of the transmission input shaft.
- Disengagement Process: When the driver depresses the clutch pedal, hydraulic or mechanical force pushes the release fork forward, moving the release bearing toward the diaphragm spring fingers of the pressure plate.
- Friction Reduction: The release bearing features a precision rolling bearing design — during high-speed rotation of the pressure plate, the bearing outer ring rotates with the pressure plate while the inner ring remains stationary, effectively reducing friction and wear.
- Power Cut-off: The release bearing pushes the diaphragm spring, separating the pressure plate from the clutch disc, cutting off engine power transmission to the transmission for gear shifting.
- Engagement Process: A return spring presses the release bearing against the release fork and returns it to its final position, maintaining a gap of approximately 3-4 mm with the end of the release lever.
Failure Symptoms
Inspect immediately if any of these occur:
| Symptom | Probable Cause |
|---|---|
| "Squeaking" or "grinding" metallic noise when depressing the clutch pedal | Worn or poorly lubricated bearing internals |
| Clutch pedal feels heavy and hard to press | Sticking or severely worn release bearing; increased resistance |
| Clutch fails to disengage fully; difficult shifting, gear grinding | Worn bearing reducing travel; pressure plate cannot fully disengage |
| Clutch shudder or vibration during driving | Uneven bearing wear causing uneven pressure plate loading |
| Increased clutch pedal free play | Bearing wear increasing clearance between fork and bearing |
| Persistent metallic noise near transmission (noticeable at idle, disappears when pedal is pressed) | Severely worn or damaged release bearing |

Important Fitment Warnings
- Number Confirmation: This product number is 1-09820115-0 / 1098201150. Reference numbers include 1-09820-115-0, 109820-1150. The same series also includes 1-09820078-0 / 1098200780. Verify the specific number on the original part before ordering.
- Associated Components: When replacing the release bearing, it is recommended to inspect or replace the clutch pressure plate and clutch disc simultaneously for optimal clutch system performance.
- Installation Lubrication: Apply high-temperature grease to the contact surfaces between the release bearing and release fork during installation to ensure smooth sliding.
- Post-Installation Adjustment: After replacing the release bearing, clutch pedal free play must be adjusted to specification to ensure proper clearance between the bearing and pressure plate diaphragm spring (approximately 3-4 mm).
- Professional Installation: The release bearing is a critical clutch system component requiring transmission removal — professional installation is strongly recommended.

Installation & Maintenance
IMPORTANT SAFETY NOTICE: The clutch release bearing is a critical clutch system component that directly affects vehicle shifting and driving safety. Replacing the release bearing requires transmission removal — a complex operation involving heavy components. Professional installation with specialized tools is strongly recommended.
Installation Guidelines (Reference Workshop Manual):
- Preparation: Confirm installation position and part number, prepare appropriate tools and replacement components
- Removing Old Release Bearing: Safely support vehicle, remove driveshaft, support transmission, and carefully remove old components
- Installing New Release Bearing: Clean mounting surfaces, lubricate contact surfaces, install new bearing, reassemble transmission
- Post-Installation Checks: Verify clutch pedal feel, shifting performance, noise levels, and perform road test
Maintenance Schedule:
