ZF 4699.199.038 LOOSE PARTS | OEM Genuine Part

Overview

The ZF 4699.199.038 LOOSE PARTS kit (SKU: 4699.199.038) is an OEM genuine assembly component designed for heavy-duty construction machinery transmissions. This specific loose parts set functions as a critical retention and alignment package within the transmission housing, securing internal shafts and gear clusters against axial movement during high-torque operation. Typically installed in the intermediate plate or rear housing section, the 4699.199.038 ensures precise spacing between rotating elements. For a complete rebuild, this kit is often paired with the 4699019001: GP19 gasket set and the 4699101152: HOUSING assembly to maintain oil sealing integrity.

Symptoms of Failure

• Transmission oil leaks at housing seams: Worn loose parts allow the housing to shift, breaking the seal between the 4699102187: INPUT section and the main case, leading to visible drips.
• Intermittent gear slipping under load: When the 4699.199.038 components fatigue, shaft end-play increases, causing the 4699103124: OUTPUT gear to lose mesh alignment during heavy excavation cycles.
• Abnormal vibration or rattle at idle: Loose retaining hardware within this kit permits internal bearing cages to chatter against the housing wall, a common indicator of imminent failure in WG-series transmissions.
• Metal debris in transmission fluid: As the loose parts degrade, they shed fine metallic particles from the retaining rings and spacers, contaminating the hydraulic circuit.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered for the WG180 and WG200 series transmissions commonly found in wheel loaders, dozers, and graders. It also supports the WG120 and WG150 models when used in conjunction with the 4699298048: OUTPUT shaft assembly. For WG310 and WG350 heavy-duty variants, verify housing bore dimensions before installation.
