FOTON Oukang TRUCK LIGHT TRUCK Vacuum Pump Assembly 70733104000
FUNCTION
1. Provides Brake Vacuum Assistance: As an engine-driven mechanical vacuum pump, it supplies a stable negative pressure to the vehicle's brake booster. This makes depressing the brake pedal lighter and less strenuous for the driver, while simultaneously and significantly enhancing braking force and response speed, thereby ensuring driving safety.
2. Generates and Maintains a Vacuum Source: Driven by the engine's camshaft or timing system, it continuously draws air from the atmosphere to generate the required vacuum pressure, serving as a power source for the braking system and other accessories that may require a vacuum supply.
3. Enhances Braking Safety: This is particularly critical in diesel engines (which lack a throttle body and typically generate lower vacuum levels during natural aspiration), ensuring that the braking system always receives ample assistance-even under heavy loads or during high-speed driving-thereby reducing braking distances and driver fatigue.
Advantages
1. Adequate and Stable Vacuum Level:* Utilizing an optimized vane or diaphragm structure, the unit rapidly generates and maintains a high level of negative pressure. This provides reliable braking assistance to the vacuum booster, ensuring a light brake pedal feel and a rapid, linear braking force response-performing exceptionally well, particularly in situations where the intake vacuum from the diesel engine is insufficient.
2. Enhanced Braking Safety: The continuous and stable vacuum output effectively reduces braking distances and improves responsiveness during emergency braking maneuvers, thereby significantly enhancing the vehicle's overall operational safety.
3. Exceptional Durability: The housing is constructed from high-strength aluminum alloy or cast iron, while critical internal components undergo precision machining and wear-resistant treatments. Boasting excellent resistance to high temperatures, oil contamination, and vibration, the unit is ideally suited for the prolonged, heavy-load operations typical of light- and medium-duty trucks, ensuring a long service life.
4. Smooth and Low-Noise Operation: Thanks to a precision dynamic balancing design and an efficient lubrication system, the pump operates with minimal vibration and low noise levels, thereby minimizing any negative impact on cabin comfort.

Daily Maintenance Suggestions
It is mounted in the timing cover area at the front of the engine and is driven directly by the engine's camshaft or timing system.
The vacuum outlet connects to the brake vacuum booster (brake assist unit) via a vacuum hose.
The oil ports connect to the engine's lubrication system (for both oil supply and return).
The drive mechanism operates in conjunction with the engine's timing system.
