Overview
The ZF 4143.110.001 LUBE OIL PUMP (SKU: 4143.110.001) is a critical hydraulic component responsible for delivering pressurized lubrication oil to the gear sets, bearings, and clutch packs within ZF WG100, WG130, and WG131 transmissions. Mounted directly to the pump housing assembly, this genuine OEM part ensures consistent oil flow to reduce friction and dissipate heat during heavy-duty operation. When paired with a properly sealed 4143101025: HOUSING, the pump maintains the hydraulic circuit integrity required for smooth shifting and extended transmission life.
Symptoms of Failure
- Low or erratic oil pressure at idle: A worn lube oil pump rotor or housing wear plate can cause pressure drops, leading to gear slipping under load and delayed clutch engagement.
- Visible oil leaks near the pump mounting flange: Degraded seals or a cracked pump body allow oil to escape, often pooling around the 0631329135: SPRING PIN retention area.
- Overheating transmission fluid: Insufficient lubrication from a failing pump causes excessive friction heat, triggering thermal warnings or burnt oil smell.
- Whining or grinding noise from the transmission sump: Cavitation or metal-on-metal contact inside the pump signals imminent failure and requires immediate replacement.

Compatibility
This lube oil pump is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits select HL 100 Series and HL 270 Series applications where the pump mounting pattern matches. For WG180 or WG200 variants, verify the pump cavity dimensions and the condition of the mating 4143301055: HOUSING before installation. Always inspect the 4143298040: CASE for scoring or wear when replacing the pump.
