Clutch Release Bearing With Housing 5-87220375-0 5872203750 For ISUZU QKR55 QKR 1.4T 2012-2018 — OEM BLOK; SHIFT, CLU Assembly

✅ Product Description

The Clutch Release Bearing with Housing (BLOK; SHIFT, CLU) with OEM numbers 5-87220375-0 (also listed as 5872203750) is a verified OEM-grade direct replacement for ISUZU QKR series light-duty trucks. This component, also referred to as a clutch shift block or release bearing seat, is a critical part of the clutch actuation system. It is installed between the clutch and the transmission, loosely sleeved on the tubular extension of the transmission's first shaft bearing cover. When the driver presses the clutch pedal, force is transmitted through the release fork to this bearing, which then contacts the pressure plate diaphragm spring to disengage the clutch. This ensures smooth clutch engagement, quiet disengagement, reduced wear, and extended service life for the entire clutch and drivetrain system.-2-3

[Failure Symptoms]
If your clutch release bearing is failing, you may experience one or more of the following symptoms:

1. Noise When Pressing Clutch Pedal: A whining, grinding, or squealing noise that appears only when the clutch pedal is depressed — the most common sign of a worn release bearing.

2. Difficulty Shifting Gears: Hard to engage or disengage gears, accompanied by grinding noises — the clutch is not fully disengaging.

3. Vibration or Juddering: Noticeable vibration felt through the clutch pedal or floor when the clutch is engaged.

4. Clutch Pedal Feels Spongy or Stiff: Abnormal pedal feel — indicates the bearing or housing is not moving smoothly along the input shaft guide tube.

5. Complete Loss of Clutch Function: In severe cases, a seized or collapsed bearing can cause total clutch failure.

⚠️ A failing clutch release bearing can lead to progressive damage to the pressure plate, flywheel, and transmission input shaft — prompt replacement is essential. It is strongly recommended to replace the release bearing, clutch disc, and pressure plate simultaneously (3-piece clutch kit).

✅ Installation & Maintenance Recommendations

⚠️ IMPORTANT: Professional Installation Highly Recommended

Clutch release bearing replacement requires transmission removal and expert knowledge of the clutch system. It is strongly recommended to replace the release bearing, clutch disc, and pressure plate as a complete 3-piece kit.

• Pre-Installation Checklist:

  • CRITICAL: Always replace the clutch disc and pressure plate simultaneously.

  • Inspect the transmission input shaft guide tube for wear or damage — replace if necessary.

  • Check the clutch release fork and pivot for wear — replace if necessary.

  • Clean the guide tube and apply a light coating of high-temperature grease.

  • Safety First: Ensure the vehicle is securely supported on jack stands. Disconnect the battery negative terminal.

Installation Guidelines (Reference ISUZU workshop manual):

1. Remove the transmission assembly from the vehicle.

2. Remove the old clutch release bearing and housing from the guide tube.

3. Clean the guide tube and bearing seat thoroughly.

4. CRITICAL: Apply a light film of high-temperature grease to the guide tube surface.

5. Install the new release bearing assembly onto the guide tube — ensure it slides smoothly.

6. Install the new clutch disc and pressure plate using a clutch alignment tool.

7. Reinstall the transmission assembly.

8. Bleed the clutch hydraulic system if necessary.

9. Adjust the clutch pedal free play as specified (typically 3-4 mm clearance between the release bearing shoulder and the release lever)-2.

10. Test drive to verify smooth gear engagement and check for unusual noises.

Maintenance Schedule:

• Inspection: During clutch service or if noise/shifting issues appear.

• Replacement: Recommended at 100,000–150,000 km or whenever the clutch is serviced.

• Note: The release bearing is a wear item — driving habits (e.g., resting foot on clutch pedal) significantly affect its service life.
