ZF 4108.016.059 P 4300 | OEM Genuine Part

Overview

The ZF 4108.016.059 P 4300 is an OEM genuine component engineered for the hydraulic control assembly within ZF heavy-duty powershift transmissions. This precision-machined part functions as a critical pressure-regulating spool or valve body element, directing oil flow to clutch packs and modulating shift quality under high torque loads. Designated by SKU 4108.016.059, it ensures consistent hydraulic pressure modulation, directly influencing transmission responsiveness and preventing premature clutch wear. This part integrates seamlessly with the 4108101166 HOUSING to form a sealed hydraulic circuit, while the 0501215601 OIL LEVEL GAGE allows technicians to verify proper fluid levels during installation.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: When the 4108.016.059 wears, internal leakage causes sluggish clutch pack pressurization, leading to harsh or delayed shifts during acceleration.
• Hydraulic oil seepage around the valve body: A worn sealing surface on this part allows pressurized ATF to bypass, often pooling near the 0501325471 SEALING RING interface.
• Transmission overheating under load: Failed pressure regulation forces the torque converter to slip excessively, generating abnormal heat that degrades fluid viscosity.
• Intermittent loss of forward or reverse drive: Internal scoring on the spool bore prevents proper oil routing, causing temporary pressure drops that mimic clutch failure.

Technical Specifications

Compatibility

This genuine ZF part is designed for use in the following transmission models: WG180, WG200, WG210, and WG250 series. It is commonly found in construction machinery such as wheel loaders, graders, and compactors. For proper assembly, always pair this component with a new 0634304358 O-RING and verify the 0730365280 TYPE PLATE for correct revision level.
