Clutch Slave Cylinder Repair Kit 5-87831402-1 5878314021 for ISUZU NKR55 4JB1 — Verified OEM Fit 22.2 mm Bore Hydraulic Clutch Sealing Kit
This repair kit is a verified direct-fit replacement for ISUZU NKR55 light trucks equipped with the 4JB1 diesel engine. This critical hydraulic sealing component restores clutch hydraulic pressure and ensures smooth, reliable clutch disengagement.
The clutch slave cylinder repair kit functions as the primary hydraulic seal within the clutch slave cylinder. It converts hydraulic pressure from the clutch master cylinder into mechanical force that pushes the clutch release fork, disengaging the clutch disc from the flywheel. The cup-shaped seal features a precisely angled sealing lip that expands under hydraulic pressure — the greater the pedal force, the tighter the seal.
