ZF 0501.334.862 BRAKE | OEM Genuine Part

Overview

The ZF 0501.334.862 BRAKE is a critical OEM genuine component designed to manage deceleration and holding torque within heavy-duty construction machinery transmissions. Positioned directly on the output shaft assembly, this brake unit engages to stop rotational motion when the vehicle is parked or during specific operational cycles. The SKU 0501.334.862 is engineered to withstand high thermal loads and abrasive environments common in earthmoving equipment. It integrates seamlessly with the HOUSING to ensure precise alignment and consistent clamping force. Without this brake, the transmission cannot safely hold a load on inclines or during stationary operation.

Symptoms of Failure

• Transmission creep on slopes: When the 0501.334.862 brake loses friction material, the machine may slowly roll forward or backward on a grade, even with the parking brake engaged.
• Delayed stopping response: Operators may notice a lag between activating the brake control and the actual halt of the driveline, indicating worn internal discs or springs.
• Oil contamination from brake dust: As the brake lining degrades, fine metallic particles enter the transmission fluid, causing dark discoloration and reduced lubrication efficiency.
• Audible grinding or squealing: A high-pitched noise during brake application suggests the friction surfaces have worn down to the metal backing plate, requiring immediate replacement.

Technical Specifications

Compatibility

This brake assembly is primarily used in ZF WG180, WG200, and WG210 series transmissions found in wheel loaders, telehandlers, and excavators. It also fits select models of the ZF 4WG-200 and 4WG-310 power shift transmissions. The 0501.334.862 interfaces directly with the INPUT shaft hub and the OUTPUT flange. For proper installation, ensure the GK10LD seal kit is used to prevent fluid bypass around the brake piston.
