ZF 4699.397.049 FRAME | OEM Genuine Part

Overview

The ZF 4699.397.049 FRAME is a structural core component within ZF heavy-duty transmission assemblies, specifically engineered to support the gear train and housing alignment in construction machinery. This OEM genuine part, identified by SKU 4699.397.049, serves as the primary mounting chassis that absorbs torsional loads and maintains precise spacing between the input and output shafts. Without this frame, the transmission cannot maintain its structural integrity under high-torque conditions. It is frequently replaced alongside the 4699101108 HOUSING and the 4699102172 INPUT assembly during a full rebuild.

Symptoms of Failure

• Transmission housing misalignment causing gear whine – A worn frame allows the 4699103057 OUTPUT shaft to shift, producing a distinct high-pitched noise during operation.
• Oil seepage at frame-to-housing mating surfaces – Cracks or fatigue in the frame lead to hydraulic fluid leaks, often mistaken for seal failure.
• Vibration under load in excavator or loader transmissions – The frame loses its damping capacity, transferring excessive vibration to the 4699001237 GK10LD clutch pack.
• Difficulty engaging forward or reverse gears – Warpage in the frame prevents proper alignment of the shift mechanism, causing intermittent gear slipping.

Technical Specifications

Compatibility

This frame is designed for ZF WG-series powershift transmissions commonly used in wheel loaders, dozers, and telehandlers. It is compatible with the following ZF transmission models:

• ZF WG180 (all variants)
• ZF WG200 (Series II and III)
• ZF WG210 (early production)
• ZF 4WG-200 (with adapter plate modification)

Always verify the frame casting number against your transmission’s serial plate before installation. The 0769100082 TYPE PLATE provides the exact model identification.
