1605010G5QZ-1107 Clutch Master Cylinder is the core hydraulic control pump for HFC1083 light truck manual clutch system. When drivers press the clutch pedal, it converts mechanical pedal movement into hydraulic pressure, transmitting fluid force to clutch slave cylinder to separate or engage clutch disc for smooth gear shifting. This aftermarket replacement part solves soft pedal feel, hydraulic fluid leaking, incomplete clutch disengagement and gear shifting difficulty caused by aging internal piston seals, corroded cylinder bore and broken push rod of original master cylinder, safeguarding stable transmission operation for urban delivery light cargo vehicles.

Constructed from high-strength grey cast iron cylinder body, resisting deformation under repeated hydraulic pressure. The built-in rubber sealing cups adopt brake fluid resistant formulation to prevent leakage. OEM matched mounting hole positions ensure direct fitment without modification. Each cylinder undergoes hydraulic pressure and leak testing before shipment, stable pressure output and greatly reduces manual gear shifting failures.

Fit for JAC HFC1083 light-duty diesel trucks, widely used in urban distribution and short-distance logistics transport vehicles with manual gearbox.

FAQ

Q1: What causes the clutch pedal to sink gradually while driving?
A1: Internal seal wear inside master cylinder leads to hydraulic pressure loss and sinking pedal symptom.
Q2: What fluid should be filled for this clutch hydraulic circuit?
A2: Use specified brake fluid; never mix different fluid types to avoid seal corrosion.
Q3: Bleeding work is required after installing new master cylinder?
A3: Yes, air bleeding is mandatory to remove trapped air inside hydraulic pipeline for normal pedal feel.
