ZF 0501.337.246 BRAKE | OEM Genuine Part

Overview

The ZF 0501.337.246 BRAKE is a critical OEM genuine component engineered for the high-torque demands of construction machinery transmissions. This part functions as a dynamic braking mechanism within the gear train, providing controlled deceleration and holding torque for heavy equipment. Specifically designed to interface with the clutch pack assembly, the 0501.337.246 ensures precise engagement and disengagement during load cycles. It sits directly adjacent to the 4699102172: INPUT shaft, where it modulates power flow to prevent driveline shock. As a genuine ZF part, it guarantees exact fitment and material integrity for prolonged service life in excavators and wheel loaders.

Symptoms of Failure

• Intermittent brake drag during operation: When the 0501.337.246 wears, the brake may fail to fully release, causing excessive heat buildup and reduced fuel efficiency. This often manifests as a “brake not releasing” issue in WG180 transmissions.
• Oil contamination from friction material: Worn brake linings shed particles into the hydraulic circuit, leading to valve sticking and erratic shifting. Look for dark, metallic-smelling transmission fluid as a key indicator.
• Loss of holding torque on inclines: A failing brake cannot maintain position on slopes, causing the machine to creep forward or backward when parked. This is a common “transmission brake slipping” complaint in construction equipment.
• Audible grinding or squealing during engagement: Metal-on-metal contact from worn friction plates produces a high-pitched noise, particularly during low-speed maneuvering or when engaging the parking brake.

Technical Specifications

Compatibility

This brake is primarily utilized in ZF WG180 and WG200 series transmissions, which are standard in mid-sized construction machinery such as telescopic handlers, backhoe loaders, and compact wheel loaders. It also fits select WG160 variants used in agricultural tractors. The 0501.337.246 interfaces directly with the 4699101108: HOUSING and the 4699001237: GK10LD clutch pack, requiring precise alignment during installation. For output-side applications, it works with the 4699103057: OUTPUT shaft assembly. Always verify transmission serial numbers before ordering, as minor revisions exist across production years.
