Clutch Master Cylinder 8-97167406-0 For ISUZU NKR55 4JB1 Truck 8981176440
Clutch Master Cylinder 8-97167406-0 For ISUZU NKR55 4JB1 Truck 89811176440
Function
Converts clutch pedal force into hydraulic pressure, activating the clutch slave cylinder to disengage the clutch for smooth, precise gear changes. Direct-fit replacement for ISUZU NKR55 with 4JB1 engine.
Product Description
The Clutch Master Cylinder Assembly (OEM Numbers: 8-97167406-0, 8-98117644-0 / 8971674060, 8981176440) is a premium-quality, direct replacement hydraulic component engineered specifically for ISUZU NKR55 series light trucks powered by the legendary 4JB1 2.8L diesel engine.
This master cylinder is the heart of the hydraulic clutch system. When the driver depresses the clutch pedal, the master cylinder converts that mechanical force into hydraulic pressure, which travels through the clutch line to the slave cylinder, disengaging the clutch and allowing smooth, noiseless gear changes.
Manufactured to meet or exceed original equipment (OE) specifications, this clutch master cylinder features a precision-machined cast iron or aluminum body, a precision-honed internal bore, and a high-quality piston assembly with double-lipped cup seals. The integrated reservoir includes a translucent body for easy fluid level inspection.
