Sinotruk WG9719230023 Master Cylinder: Precision Hydraulic Flow

High-precision clutch control for responsible mobility

THE Sinotruk master cylinder (reference WG9719230023) is the critical control component for the smooth operation of your transmission on the models Howo, A7 and Steyr. Designed to instantly convert the force applied to the pedal into constant hydraulic pressure, it ensures smooth, clean, and effortless clutch disengagement. With a view to sustainable maintenance, This high-performance component prevents internal leaks and hard spots, thus optimizing the energy efficiency and longevity of your clutch kit.

True to our commitment to technical transparency, This original equipment manufacturer (OEM) quality part guarantees total operational reliability, meeting the productivity requirements of truck owners operating in demanding environments.

Technical Characteristics & Flow Resilience

Cutting-edge engineering for reliability that meets international standards:

• Precision Machining of the Body: Optimized internal walls for perfect lubrication, meeting the requirements of high-performance standards API CH4/SJ And MB 228.1, providing anti-friction protection for the piston.

• Interactions with Fluids: The cups and internal seals are designed for perfect compatibility with a high-quality base oil (control liquid), equipped with a strong viscosity index, guaranteeing consistent order responsiveness -40°C à +120°C.

• Maximum Thermal Resilience: Alloys and polymers exhibit a high sublimation point technical (structural stability), preventing any micro-deformation or loss of pressure under the effect of the intense heat radiated by the engine.

• Certified Hydraulic Sealing: Precision calibration of the valves to ensure immediate force transfer, eliminating latency during gear changes under heavy load.

Your Advantages

• Eco-design (Ocean Bound Plastic): We are taking action for biodiversity: the transport caps and protective films of this master cylinder incorporate certified polymers. Ocean Bound Plastic, actively participating in the cleanup of marine ecosystems.

• Industrial Ethics (Vegan & Leaping Bunny): Manufacturing process guaranteed to be free of any animal-derived components. Certification Leaping Bunny ensuring the absence of animal testing for storage fluids and protective varnishes.

• «High SPF» Anti-Corrosion Protection: The external structure benefits from a high-density treatment, "« moisturizing »" (action moisturizing (technical) the alloy to prevent premature oxidation due to humidity or mud splashes.

• "Non-Greasy" Finish & Precise Assembly: Unit supplied with a surface finish« non-greasy«", preventing the adhesion of abrasive dust and ensuring a surgical installation on your cabin apron.
