ZF 0501.329.347 BRAKE | OEM Genuine Part

Overview

The ZF 0501.329.347 BRAKE is a critical OEM genuine component designed for high-stress environments within ZF construction machinery transmissions. This part functions as a dynamic braking element, engaging to slow or stop the output shaft under heavy loads. It sits within the transmission’s clutch pack assembly, directly interfacing with the housing and planetary gear sets. The SKU 0501.329.347 ensures precise fitment and durability, reducing downtime in excavators, loaders, and graders. When replacing this brake, it is common to also inspect the 4699101094: HOUSING for wear, as housing cracks can accelerate brake degradation.

Symptoms of Failure

• Transmission brake drag or overheating: A worn 0501.329.347 brake can fail to fully disengage, causing friction and excessive heat. This often manifests as a burning smell or discolored transmission fluid.
• Intermittent gear slipping under load: When the brake loses friction material, the transmission may slip during acceleration on inclines, particularly in WG180 and WG200 series units.
• Oil leaks near the brake piston area: Deteriorated seals around this part allow hydraulic fluid to bypass, leading to visible drips and low pressure warnings. Check the 4699103063: OUTPUT shaft seal simultaneously.
• Grinding or clunking noises during shifting: Metal-on-metal contact from a worn brake plate produces audible grinding, especially when shifting from forward to reverse.

Technical Specifications

Compatibility

This brake plate is engineered for ZF’s heavy-duty transmission families, specifically the WG180, WG200, and WG250 series used in construction machinery. It also fits select Ecomat and PowerLine variants where the brake pack shares the same spline count and stack height. For complete assembly, pair this part with the 4699001092: GK10 gear kit and the 0501329881: HOUSING COVER to ensure proper sealing and alignment.
