Product Introduction 1607300LE35R Clutch Booster is a pneumatic power assisting component for HFCN721 light truck manual transmission clutch control system. It amplifies the force from clutch master cylinder by using compressed air, reducing the pedal pressing effort for drivers when engaging or disengaging clutch. This aftermarket replacement booster resolves heavy clutch pedal feeling, incomplete clutch separation, slipping clutch and continuous air leakage caused by aging internal diaphragm, sticking piston and cracked housing of original boosters, making gear shifting smoother and protecting clutch disc for urban logistics light cargo vehicles.

Product Advantages High-strength cast aluminum housing resists impact and corrosion in rough chassis environment. Reinforced rubber diaphragm maintains reliable sealing under cyclic air pressure changes. Precision internal piston structure ensures sensitive power assistance response. Each booster undergoes air tightness and dynamic performance testing before shipment, matching original mounting dimensions and simplifying chassis maintenance work.

Applicable Models Fit for JAC HFCN721 light truck series, matches original clutch servo assembly widely used for short-distance delivery and urban logistics cargo vehicles.

FAQ

Q1: Can water inside air tank shorten the service life of clutch booster?
A1: Definitely, moisture in compressed air will corrode internal piston and degrade rubber diaphragm quickly.
Q2: Is it possible to repair a leaking clutch booster instead of full replacement?
A2: Minor seal damage can be fixed with repair kit, full replacement is recommended if housing has cracks.
Q3: Why gear shift becomes difficult after booster failure?
A3: Power assist disappears, you need much larger pedal force and clutch may not fully separate.
