Overview
The ZF 2099.140.016 HOISTING UNIT is a critical OEM genuine component engineered for the demanding environment of construction machinery. This precision-machined assembly governs the lifting and lowering functions within the transmission system, directly interfacing with the hydraulic circuit to control load movement. As an integral part of the driveline, the SKU 2099.140.016 ensures that power is transmitted smoothly from the engine to the hoisting mechanism, preventing uncontrolled descent or sluggish operation. When paired with the 2099109002: DIFFERENTIAL and the 2099364014: CROWN WHEEL, this unit forms the backbone of reliable material handling in wheel loaders and telehandlers.
Symptoms of Failure
When the ZF 2099.140.016 hoisting unit begins to degrade, operators will notice distinct performance issues. Oil leaks around the hoist valve body are a primary indicator, often appearing as drips or puddles beneath the transmission housing. Intermittent gear slipping during load lift occurs as internal seals lose integrity, causing pressure drops. Another common symptom is erratic or jerky hoist movement, where the unit fails to maintain steady hydraulic flow. Finally, excessive noise during operation—a whining or grinding sound—signals worn bearings or scored internal components. Addressing these signs early prevents cascading damage to the 2099209001: DIFFERENTIAL and the 2098309010: DIFFERENTIAL HOUSING.

Compatibility
This hoisting unit is designed for integration into ZF’s heavy-duty transmission families commonly found in construction machinery. It is compatible with the WG180 and WG200 series, as well as the WG210 and WG310 models. These transmissions are used in wheel loaders, backhoe loaders, and telescopic handlers from manufacturers such as Liebherr, JCB, and Caterpillar. For precise fitment, always verify the transmission serial number against the ZF parts catalog. The unit works in concert with the 2098309009: DIFFERENTIAL HOUSING and the 2098309031: AXLE BEVEL GEAR to ensure complete driveline harmony.
