ZF 2093.128.016 BRAKE | OEM Genuine Part

Overview

The ZF 2093.128.016 BRAKE is a critical OEM genuine component engineered for the demanding environment of construction machinery transmissions. This part functions as the primary holding and stopping mechanism within the gearbox assembly, directly engaging with the output shaft to control rotational motion under heavy loads. As an integral safety and control element, the SKU 2093.128.016 ensures precise deceleration and stationary hold for wheel loaders and graders. When paired with the 2093140001: HOISTING UNIT, the brake system manages both travel and lifting functions, while the 2093240001: LIFTING SHAFT transfers torque through the same housing. This brake assembly is designed to withstand high thermal stress and frequent cycling, making it indispensable for maintaining operational uptime in earthmoving equipment.

Symptoms of Failure

When the ZF 2093.128.016 BRAKE begins to wear, operators will notice specific performance degradation. Delayed stopping response is the most common early indicator, where the machine continues to creep after the brake pedal is fully depressed. Another frequent issue is intermittent brake drag, causing the transmission to overheat during normal operation. You may also detect metallic grinding noises from the axle housing, particularly during low-speed turns. Finally, hydraulic fluid contamination from worn friction material can be observed during routine oil sampling, leading to accelerated wear on the 2095340002: BUSH and surrounding components.

Technical Specifications

Compatibility

This brake is specifically engineered for ZF’s heavy-duty powershift transmission series. It is a direct fit for the WG180, WG200, and WG250 models commonly found in Volvo, Caterpillar, and Komatsu wheel loaders. The part also integrates with the 4WG-200 and 6WG-250 variants used in graders and dozers. For proper installation, ensure the 2093340007: BRACKET is correctly aligned to prevent uneven wear on the disc pack.

Frequently Asked Questions

Q: Can the ZF 2093.128.016 brake be rebuilt with aftermarket friction discs?
A: While aftermarket discs may fit, we strongly recommend using only OEM genuine parts for this brake assembly. The sintered bronze material composition is precisely matched to the hydraulic pressure curves of ZF transmissions, and using non-OEM components can lead to premature failure or erratic braking behavior.

Q: How often should this brake be inspected in construction machinery?
A: For machines operating in high-dust or high-load environments (e.g., quarry loaders), inspect the brake pack every 1,000 operating hours. Look for disc thickness variation exceeding 0.5 mm or any signs of heat discoloration on the steel separator plates.

Q: Is the 2093.128.016 compatible with the ZF 4WG-310 transmission?
A: No, the 4WG-310 uses a larger 320 mm brake disc. This part is strictly for WG180, WG200, and WG250 series transmissions. Always verify your transmission model plate before ordering.
