Product Detail

800901152 Air Booster Pump / Brake Booster for XCMG Wheel Loader

The 800901152 Air Booster Pump (Air Brake Booster) is a critical component in the air-over-hydraulic braking system for select XCMG wheel loaders. Also known as a brake booster or air chamber boosting pump, this part amplifies the force applied to the brake pedal using compressed air, ensuring reliable stopping power for heavy machinery under demanding operating conditions .

Braking Force Amplification: Uses compressed air from the air tank to multiply hydraulic pressure applied to brake calipers, enabling the heavy loader to stop effectively even when carrying full loads .
Air-Over-Hydraulic Operation: Combines pneumatic assistance with hydraulic actuation, providing consistent stopping power regardless of load weight or terrain conditions.
Critical Safety Component: A properly functioning booster pump is essential for operator safety and machine control. Failure can lead to braking force deficiency where the loader does not slow down or stop as required.

The 800901152 air booster pump is confirmed to fit the following XCMG equipment models:

Equipment Type	Models
Wheel Loaders	ZL50G, ZL50GN, LW500FN, LW300FN, LW300F
Motor Grader	GR1803BR

Parameter	Value / Description
Part Number (XCMG OEM)	800901152
Cross-Reference Part No.	4120000090, XZ-60
Alternative Name	Booster Pump Assembly XC60
Product Name	Air Booster Pump / Air Brake Booster / Air Chamber Boosting Pump
Function	Braking force amplification using compressed air
Application	XCMG wheel loader and motor grader braking system
Weight	Approx. 6 kg
Dimensions (Package)	Approx. 20 × 30 × 20 cm
Warranty (Supplier)	Up to 3 years (supplier-dependent)
Condition	100% new

Brake System Bleeding: If air enters the hydraulic brake system during installation, it can cause braking retardation or deficiency. Bleeding the system to remove trapped air is essential after installation.
Booster Pump Failure Symptoms: Common signs of a damaged booster pump include reduced braking power, a spongy brake pedal, or the loader failing to stop as required. The piston seal may be damaged or worn, requiring replacement.
Direct Replacement: This part is designed as a direct bolt-on replacement for the original component on compatible XCMG ZL and LW series loaders.
