ZF 2098.328.009 DRIVER | OEM Genuine Part

Overview

The ZF 2098.328.009 DRIVER is a critical rotational component engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as the primary torque transfer element within the clutch pack assembly, converting hydraulic pressure into mechanical motion to engage gear sets. Positioned directly on the main shaft, the 2098.328.009 DRIVER interfaces with the 2098117002: HOUSING to ensure precise alignment and load distribution. Its hardened steel construction resists wear from constant high-torque cycling, making it essential for maintaining driveline integrity in wheel loaders, graders, and dump trucks. The SKU 2098.328.009 is a direct replacement for original equipment, eliminating guesswork during rebuilds.

Symptoms of Failure

• Delayed engagement or gear slipping – When the DRIVER wears, it fails to lock clutch plates promptly, causing hesitation when shifting from neutral to drive. This is often searched as “ZF transmission slow to engage” or “transmission slipping under load.”
• Metallic grinding noise from the bell housing – A worn driver surface creates uneven contact with the 2098301052: REAR AXLE HOUS., producing a distinct scraping sound during acceleration. Operators frequently search for “grinding noise in ZF transmission” or “transmission whine when moving.”
• Transmission fluid contamination with metal particles – As the driver’s splines degrade, microscopic steel fragments enter the hydraulic circuit. This symptom is commonly queried as “metal shavings in transmission oil” or “ZF transmission filter clogged with debris.”
• Intermittent loss of power to wheels – A fractured driver hub can cause sudden torque dropouts, especially under heavy loads. This failure mode is often described as “transmission losing power intermittently” or “ZF transmission jumps out of gear.”

Technical Specifications

Compatibility

This DRIVER is designed for ZF’s WG series powershift transmissions commonly found in construction machinery. It is a direct fit for the following models: WG180, WG200, WG211, and WG250. These transmissions are used in OEM equipment from Caterpillar, Volvo, Komatsu, and Case. The part also integrates with the 2098317013: BRAKE HOUSING and 2098317028: BRAKE HOUSING for parking brake assemblies. Always verify your transmission serial number before ordering, as minor spline variations exist between early and late production units.
