ZF 4143.151.017 MULTIDISK BRAKE | OEM Genuine Part

Overview

The ZF 4143.151.017 MULTIDISK BRAKE is a critical friction component engineered for precise torque control within ZF powershift transmissions. This OEM genuine part functions as a hydraulically actuated brake pack, engaging to hold planetary gear sets stationary during clutch-to-clutch shifts. Located within the transmission’s rotating clutch drum assembly, the multidisk brake absorbs high thermal loads and provides consistent stopping force under heavy-duty cycles. The SKU 4143.151.017 is specifically designed for the HL 100 Series and HL 270 Series, ensuring direct OEM fitment without modification. When paired with the 4143101031 HOUSING and 4143301055 HOUSING, this brake assembly maintains proper oil flow and pressure containment for reliable operation.

Symptoms of Failure

• Delayed or harsh engagement when shifting from neutral to drive: Worn friction discs cause the brake pack to slip, leading to a noticeable lag or jarring engagement under load.
• Transmission overheating during low-speed maneuvering: Excessive slippage from degraded multidisk surfaces generates abnormal heat, often triggering thermal warnings or fluid breakdown.
• Metallic grinding noise during directional changes: Severely worn steel separator plates can contact the 4143298040 CASE, producing audible metal-on-metal sounds.
• Intermittent loss of drive in forward gears: Internal leakage past worn brake seals reduces hydraulic clamping force, causing intermittent power loss that worsens with temperature.

Technical Specifications

Compatibility

This multidisk brake is primarily compatible with ZF HL 100 Series and HL 270 Series transmissions used in wheel loaders, forklifts, and industrial tractors. Based on the part type and dimensions, it also fits select WG180 and WG200 powershift models where the brake pack shares identical spline counts and piston stroke requirements. Always verify the friction disc count and steel plate thickness against your existing assembly. For proper installation, ensure the 0631329135 SPRING PIN is correctly aligned to prevent rotation of the brake hub during assembly.
