Product Introduction:
Part number 0750 132 143 (also written as 0750132143) is a gear pump for ZF transmissions, compatible with the ZF 4WG180, 4WG200, and 6WG200 series. It is mounted in the transmission input section and supplies oil pressure for internal lubrication and shift control.
1. Installation Location
This pump is installed in the input section of the ZF WG200 series transmission and is driven by the transmission input shaft. On the FL958 loader, the transmission is coupled to the engine flywheel housing, and the pump is located inside the front of the transmission.
2. Function
The gear pump draws transmission oil from the sump and delivers it under pressure to lubrication points and the hydraulic control valve body inside the transmission. It maintains the oil pressure and flow required by the shift clutches, torque converter, and bearings, ensuring smooth shifting and adequate lubrication and cooling of drivetrain components. Insufficient pump delivery can cause shift shock, clutch slippage, or transmission overheating.
3. Maintenance and Service
Regular inspection includes checking the pump body and connections for external leaks, and verifying transmission oil level and condition. If shift delay, abnormal noise, or low oil pressure occurs, the pump should be inspected. It is a precision hydraulic component and is not internally serviceable; if a fault is confirmed, replace it with an identical 0750 132 143 unit. Drain the transmission oil and clean the mounting surface before replacement.
4. Important Notes
Before installation, verify that part number 0750 132 143 (or 0750132143) matches the original component. This pump also cross-references to XCMG part number 860116268 and LiuGong SP100277. Confirm the transmission model is ZF 4WG180/4WG200/6WG200 series. Use ZF-specified transmission oil and maintain the correct oil level.
