The Main Clutch Pump, part number LG9704230201, is the clutch master cylinder. It mounts directly to the firewall or pedal bracket. The push rod connects to the clutch pedal mechanism. When the pedal is pressed, the rod moves the internal piston.
This piston compresses the hydraulic fluid in the bore. It generates high-pressure fluid flow through the line. This pressure actuates the clutch slave cylinder. The slave cylinder then disengages the clutch plate.
The efficiency of the pump is critical. It determines the pedal feel and shift smoothness. A genuine unit ensures precise hydraulic pressure buildup. This allows for clean and quick gear changes.
Precise Hydraulic Pressure Generation
The Main Clutch Pump With Push Rod features a precision-honed bore and piston. This ensures consistent and immediate pressure response for reliable clutch control.
Robust Construction for Longevity
Built with high-strength materials and corrosion-resistant finishes, the Main Clutch Pump With Push Rod withstands millions of pedal cycles without failure.
Perfect Pedal Feel and Feedback
Engineered to provide the correct resistance and travel, this pump gives the driver optimal tactile feedback for smooth shifting.
Direct OEM Fit and Integration
The LG9704230201 bolts directly into place, with the push rod correctly aligned to the pedal, ensuring hassle-free installation.

A failing LG9704230201 clutch master cylinder presents clear warning signs. A soft or spongy clutch pedal is the most common symptom. The pedal may sink slowly to the floor when pressed and held.
Visible fluid leaks around the pump body indicate seal failure. Low fluid level in the reservoir without external leaks points to internal leakage. Difficulty shifting gears or clutch drag are serious symptoms.
To diagnose, check for fluid on the interior firewall carpet. Inspect the boot around the push rod for moisture. A faulty LG9704230201 pump often requires replacement of the complete unit.
Do not ignore these signs. A failing pump can lead to complete clutch failure. This makes the vehicle undriveable and poses a safety risk. Prompt replacement with a genuine LG9704230201 is recommended.
Replacing the main clutch pump is a precise task. Begin by safely securing the vehicle. Disconnect the battery to prevent electrical shorts. Syringe out the old fluid from the clutch reservoir.
Disconnect the hydraulic fluid line from the LG9704230201 pump. Use a flare nut wrench to avoid damaging the fitting. Inside the cab, disconnect the push rod from the clutch pedal assembly.
Remove the mounting bolts securing the old pump. Carefully remove the unit from the firewall. Compare the new genuine LG9704230201 with the old part to confirm fitment.
Install the new pump and tighten bolts to specification. Reconnect the push rod to the pedal. Attach the hydraulic line. Refill the system with fresh DOT 4 fluid. Bleed the clutch system thoroughly to remove all air.
The hydraulic clutch is a force multiplier. It allows the driver to disengage a heavy-duty clutch with minimal effort. The LG9704230201 pump is the control point for this system.
Its performance affects gearshift speed and smoothness. A well-functioning pump reduces wear on synchronizers. It also prevents premature failure of the clutch release bearing.
Regular maintenance of the entire system is crucial. This includes using quality fluid and checking for leaks. The LG9704230201 is a wear item and will eventually need service.
Genuine SINOTRUK Howo parts are designed for exact fit and function. The LG9704230201 pump matches the original bore size and stroke length. This ensures correct pedal travel and pressure.
The internal seals are made from fluid-resistant compounds. They withstand high temperatures and pressures. Non-genuine parts often use inferior seals that fail quickly.
The push rod on the genuine LG9704230201 is correctly heat-treated. It resists bending and wear at the pivot points. This guarantees long-term reliability and consistent performance.
The Main Clutch Pump with Push Rod, OEM number LG9704230201, is a vital hydraulic component. Its role in translating pedal action into clutch disengagement is indispensable for vehicle operation.
Investing in the genuine LG9704230201 part guarantees the performance, safety, and longevity of your SINOTRUK Howo’s clutch system. Maintain optimal driving control and prevent costly downtime by choosing authentic OEM components for all critical repairs.
