ZF 4699.170.283 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.283 MOTOR is a critical hydraulic drive component engineered for high-torque applications within ZF construction machinery transmissions. This OEM genuine part converts hydraulic pressure into rotational force, directly powering the driveline in wheel loaders, telehandlers, and heavy-duty graders. Positioned at the interface between the pump and the gear train, the SKU 4699.170.283 ensures precise speed control and reliable power delivery under extreme loads. As a direct replacement, it maintains the original factory tolerances required for seamless integration with the transmission housing and output assembly.

Symptoms of Failure

• Erratic or delayed engagement: When the motor wears, operators notice hesitation or jerky movement when shifting from forward to reverse, often accompanied by a whining noise during low-speed operation.
• Hydraulic fluid contamination: Internal seal degradation allows metal particles to enter the oil, causing dark, gritty fluid and reduced system pressure. This is a common sign of imminent motor failure.
• Overheating transmission: A failing 4699.170.283 generates excessive friction, leading to elevated oil temperatures above 100°C (212°F) during normal cycles, which can damage adjacent components like the HOUSING.
• Loss of torque under load: The machine struggles to climb grades or lift rated capacities, indicating the motor can no longer maintain hydraulic pressure to the OUTPUT shaft.

Technical Specifications

Compatibility

This motor is designed for ZF WG series transmissions commonly used in construction machinery. It directly fits the WG180, WG200, and WG210 models, which power equipment from manufacturers like Liebherr, Caterpillar, and Volvo. The 4699.170.283 also integrates with the GK10LD gearbox assembly and the INPUT shaft module. For proper installation, ensure the mating HOUSING is free of wear and the OUTPUT splines are undamaged.
