ZF 2095.229.003 BRAKE SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.229.003 BRAKE SHAFT is a critical actuation component within the ZF WG100, WG130, and WG131 powershift transmission series. This OEM genuine part transmits mechanical force from the brake piston to the clutch pack, ensuring precise engagement and disengagement of the transmission brake. As a hardened steel shaft, it sits directly within the planetary gear assembly and interfaces with the differential housing. The SKU 2095.229.003 is the exact replacement for the original factory-installed brake shaft, guaranteeing correct spline alignment and load distribution. When paired with a properly functioning 5838109007: DIFFERENTIAL, this shaft ensures smooth power interruption during gear shifts.

Symptoms of Failure

• Transmission brake drag or incomplete release: A worn brake shaft can cause the brake to remain partially engaged, leading to overheating and reduced fuel efficiency.
• Intermittent gear slipping under load: When the shaft loses its surface hardness or develops spline wear, the brake pack cannot hold torque, resulting in erratic shifting.
• Metallic grinding noise during deceleration: Excessive play in the shaft bore creates audible contact with the 0750117075: TAPER ROLLER BEARING, producing a distinct grinding sound.
• Oil contamination from brake debris: Fractured shaft material can enter the hydraulic circuit, clogging valves and accelerating wear on the 2095209019: DIFFERENTIAL assembly.

Technical Specifications

Compatibility

This brake shaft is specifically engineered for ZF WG-series transmissions with mechanical brake actuation. It is a direct fit for WG100, WG130, and WG131 models. The part also serves as a service replacement for earlier WG80 variants when used with the appropriate 0631329086: SPRING PIN for retention. It is not compatible with WG180 or WG200 series without additional adapter components. Always verify shaft length against your existing unit before installation.
