ZF 2099.060.009 TRA 16 | OEM Genuine Part

Overview

The ZF 2099.060.009 TRA 16 is a critical OEM genuine component engineered for the final drive assembly of heavy-duty construction machinery transmissions. This part functions as a precision-machined spacer or thrust element within the differential housing, ensuring correct axial clearance and load distribution between rotating gears. The SKU 2099.060.009 is specifically designed to maintain gear mesh alignment under extreme torque loads, preventing premature wear on adjacent components. It sits directly between the differential case and the axle bevel gear assembly, acting as a sacrificial wear interface that protects more expensive transmission housings.

Symptoms of Failure

When the ZF 2099.060.009 TRA 16 begins to degrade, operators will notice distinct operational issues. Oil leaks from the differential housing are common, as a worn spacer compromises the seal surface. Intermittent gear slipping under load occurs when axial play exceeds factory tolerances. Metallic grinding noises during turns indicate the spacer has thinned, allowing gear teeth to contact improperly. Increased vibration at the drive axle is another clear sign, often accompanied by visible metal particles in the transmission fluid.

Technical Specifications

Compatibility

This genuine ZF part is compatible with the following transmission models: WG180, WG200, WG211, and WG250 series used in wheel loaders, graders, and compactors. It also fits select ZF 4WG-200 and ZF 6WG-250 powershift transmissions. Always verify your transmission serial number before ordering.

During installation, this spacer works in concert with the 2099109004 DIFFERENTIAL to establish proper gear preload. The 0750117075 TAPER ROLLER BEARING must be inspected simultaneously, as bearing wear accelerates spacer failure. For complete differential rebuilds, pair this part with the 2093209095 DIFFERENTIAL and the 2093309071 DIFF.HOUSING to ensure all mating surfaces meet OEM tolerances.
