The Concentric Clutch Slave Cylinder (Hydraulic Release Bearing Assembly) with OEM number ME538976 (also listed as ME523208, ME523197) is a verified OEM-grade direct replacement for Mitsubishi Fuso Canter trucks equipped with the 4M50 and 4M51 series diesel engines.
Manufactured to Mitsubishi's stringent OEM specifications, this component combines the clutch slave cylinder and release bearing into a single, integrated unit mounted concentrically around the transmission input shaft. As a critical component of the hydraulic clutch system, it converts hydraulic pressure from the clutch master cylinder into mechanical force to directly actuate the clutch diaphragm spring, enabling smooth gear engagement and disengagement in commercial transport applications.

If your concentric clutch slave cylinder is failing, you may experience one or more of the following symptoms:
- Soft or Spongy Clutch Pedal — Pedal feels unusually soft, spongy, or goes to the floor without resistance
- Difficulty Shifting Gears — Hard to engage or disengage gears, accompanied by grinding noises
- Clutch Drag / Incomplete Disengagement — Vehicle creeps forward with clutch fully depressed, or gears grind when shifting
- Visible Fluid Leakage — Brake/clutch fluid seeping from the bell housing area
- Clutch Pedal Heavy or Stiff — Pedal requires excessive force to depress
- Unusual Noises — Grinding or squealing noises from the transmission area

Replacing a concentric slave cylinder requires transmission removal and expert knowledge of clutch hydraulic systems.
Pre-Installation Checklist:
- The transmission must be removed to access the concentric slave cylinder inside the bell housing
- Inspect the clutch disc, pressure plate, and flywheel for wear — replace as necessary
- CRITICAL: Always replace the clutch disc and pressure plate simultaneously for optimal performance
- Use new brake fluid (DOT 3 or DOT 4) from a sealed container
- Bleed the clutch hydraulic system thoroughly after installation
Maintenance Schedule:
- Inspection: Every 50,000 km / 12 months. Check for fluid leaks, pedal feel, and smooth gear engagement
- Fluid Replacement: Every 2 years or 40,000 km — replace clutch fluid to prevent internal corrosion
- Replacement: Immediately if failure symptoms appear
- Packaging: Each concentric clutch slave cylinder is securely packed in protective packaging
- Net Weight: Approx. 2.4 kg/pc
- Warranty: 12 Months
- Suitable for: Wholesale distributors, truck parts retailers, commercial vehicle repair shops, and fleet owners
