Product Detail

800901159 / 860165996 Air Booster Pump (Brake Booster) for XCMG Wheel Loader

The 800901159 Air Booster Pump (cross-reference: 860165996), also known as an air brake booster or air, is a critical safety component in the air-over-hydraulic braking system of XCMG wheel loaders. It is a direct OEM replacement part designed for models including the ZL50C, ZL50G, LW500K, and LW500KN series .

This component amplifies the force applied to the brake pedal using compressed air, ensuring reliable and powerful braking performance for heavy machinery under demanding operating conditions .

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

The 800901159 air booster pump is confirmed to fit the following XCMG wheel loader models:

Model Series	Specific Models
ZL Series	ZL50C, ZL50G
LW Series	LW500K, LW500KN

Parameter	Value / Description
Part Number (XCMG OEM)	800901159
Cross-Reference Part No.	860165996
Alternative Part No.	XZ50K-3510002
Product Name	Air Booster Pump / Air Brake Booster
Function	Braking force amplification using compressed air
Application	XCMG wheel loader braking system
Weight	Approx. 6 kg (typical)
Warranty	1 year (supplier-dependent)

Air in the System: If air enters the hydraulic brake system, 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 have been damaged or the piston cup may be 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.
