ZF 4108.016.012 P 4300 | OEM Genuine Part

Overview

The ZF 4108.016.012 P 4300 is an OEM genuine pressure control valve assembly, engineered specifically for the hydraulic control unit within heavy-duty ZF transmissions. This component regulates clutch engagement pressure, ensuring smooth power delivery in construction machinery. As part number 4108.016.012, it sits directly within the main valve body, interfacing with the 4108101108: HOUSING to direct oil flow. The valve’s precision spool and bore maintain consistent hydraulic pressure, preventing erratic shifting under high torque loads. Its robust steel construction withstands the thermal and mechanical stress common in excavators and wheel loaders.

Symptoms of Failure

• Delayed or harsh gear engagement – When the valve spool sticks, hydraulic pressure spikes, causing jarring shifts during acceleration or deceleration.
• Intermittent transmission slipping – Worn internal seals allow pressure loss, leading to clutch pack slip under load, especially in low gears.
• Hydraulic oil contamination – Debris from a failing valve can circulate through the system, accelerating wear on the 4108301436: INPUT SHAFT and bearings.
• Visible external leakage – Cracks in the valve body or degraded O-rings cause oil seepage around the 4108306172: GASKET mating surface.

Technical Specifications

Compatibility

This pressure control valve is designed for ZF WG series transmissions commonly used in construction equipment. It is a direct fit for the WG180, WG200, and WG210 models. It also applies to the Ecomat 4HP and 6HP series found in older mobile machinery. Always verify the 0730365280: TYPE PLATE on your transmission housing to confirm model compatibility before installation.
