ZF 2094.140.004 POWER LIFT | OEM Genuine Part

Overview

The ZF 2094.140.004 POWER LIFT is a critical OEM genuine component engineered for heavy-duty construction machinery transmissions. This hydraulic power lift assembly provides the necessary force to engage and disengage the PTO (Power Take-Off) clutch pack, enabling auxiliary equipment operation such as dump bodies, winches, or concrete mixers. Positioned within the upper valve body section of the transmission, it interfaces directly with the 2094101011: TRANSMISSION HOUSING and the 2094301045: HOUSING to regulate hydraulic flow. The SKU 2094.140.004 is precision-machined to ZF factory tolerances, ensuring reliable lifting capacity under extreme loads.

Symptoms of Failure

• Intermittent PTO engagement failure: When the power lift wears, the transmission may fail to engage the PTO consistently, causing sudden loss of hydraulic power to auxiliary equipment.
• Hydraulic oil leaks near the valve body: Worn seals or cracked lift pistons allow transmission fluid to seep past the 0635460022: BALL check valve, leaving puddles under the chassis.
• Delayed or sluggish lifting response: A degraded power lift reduces hydraulic pressure, causing a 2-3 second delay before the PTO engages, which can damage driveline components.
• Unusual grinding or whining noises: Metal-on-metal contact from a failing lift piston produces audible noise during PTO activation, indicating imminent internal damage.

Technical Specifications

Compatibility

This power lift is designed for ZF WG-series transmissions commonly found in construction loaders, graders, and dump trucks. It is compatible with the following ZF models: WG180, WG200, WG210, and WG250. The part also fits select ErgoPower and Ecolife variants used in Volvo, Liebherr, and Caterpillar equipment. For proper installation, ensure the 2094301044: COVER is torqued to factory specifications to prevent fluid bypass.
