ZF 4660.175.005 REVERSING GEAR for WG92 | OEM Genuine Part

Overview

The ZF 4660.175.005 REVERSING GEAR is a critical directional control component engineered specifically for the WG 92 Series transmission. This OEM genuine part manages torque flow reversal, enabling smooth shuttle shifts in industrial drivetrains. Positioned within the transmission’s planetary gear set, the 4660.175.005 engages and disengages forward and reverse rotation under load. The SKU 4660.175.005 is precision-machined to ZF’s exacting tolerances, ensuring seamless integration with the 4660101017: TRANSMISSION HOUSING and the 4660301054: HOUSING II to maintain hydraulic pressure integrity during gear changes.

Symptoms of Failure

• Delayed or harsh directional shifts — When the reversing gear wears, operators experience a noticeable lag or clunk when switching from forward to reverse, often accompanied by grinding noises.
• Transmission fluid contamination — Metal particles from a failing 4660.175.005 gear appear in the oil filter, indicating advanced wear that can clog the 4660221029: SUCTION TUBE.
• Intermittent power loss in reverse — The vehicle may lose torque output specifically in reverse gear, while forward operation remains normal, pointing to a worn reversing gear.
• Oil leaks near the housing interface — Degraded sealing surfaces on the gear cause fluid seepage around the 0631306174: CYLINDRICAL PIN and housing joints.

Technical Specifications

Compatibility

This reversing gear is designed for the ZF WG 92 Series transmission family. It is also compatible with the WG180, WG200, and WG240 models that share the same planetary gear architecture. The 4660.175.005 interfaces directly with the 0769123894: TYPE PLATE for identification and requires proper torque specifications when installed with the 0636103273: CAP SCREW and 0750100022: SCREW PLUG. Always verify your transmission serial number against ZF’s OEM catalog before ordering.
