ZF 0501.213.942 STEERING GEAR for WG100/WG130/WG131

Overview

The ZF 0501.213.942 STEERING GEAR is a critical component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part precisely controls hydraulic flow within the steering system, converting rotational input from the steering wheel into the mechanical force required to articulate the vehicle. Positioned within the valve housing assembly, the 0501.213.942 gear interfaces directly with the main control spool to regulate pressure and direction. When paired with a robust 4699101045: HOUSING, this steering gear ensures smooth, responsive handling under heavy loads. The SKU 0501.213.942 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in demanding industrial applications.

Symptoms of Failure

• Erratic steering response or “jerky” wheel movement: Worn internal splines or gear teeth cause inconsistent engagement, leading to sudden lurches during low-speed maneuvering.
• Hydraulic oil leaks near the steering column: Degraded seals around the 0501.213.942 allow transmission fluid to escape, often pooling beneath the chassis after extended operation.
• Increased steering effort or “stiff” wheel: Internal galling or debris contamination within the gear set creates excessive friction, requiring more force to turn the wheel.
• Unusual whining or grinding noises during articulation: Metal-on-metal contact from worn gear surfaces produces audible distress signals, particularly when turning at full lock.

Technical Specifications

Compatibility

This steering gear is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct 4699301108: HOUSING adapter. For WG131 applications, the 4699301085: COVER must be installed to maintain proper sealing. Always verify the spline configuration against your existing unit; the 0501.213.942 replaces earlier revisions 0501.213.940 and 0501.213.941. Use a 4699301014: THREAD PROTECTIVE SHIELD during installation to prevent thread damage.
