ZF 2095.303.037 GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.303.037 GEAR is a precision-machined helical gear designed for the intermediate shaft assembly within ZF’s WG100, WG130, and WG131 powershift transmissions. This OEM genuine part, identified by SKU 2095.303.037, serves as a critical torque-transfer component between the input shaft and the differential output. It directly meshes with the 5838109021: DIFFERENTIAL to modulate gear ratios during load shifts. Manufactured from case-hardened alloy steel, it ensures minimal backlash and sustained power flow under high-torque industrial applications.

Symptoms of Failure

• Whining or howling noise during deceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched whine that intensifies when the transmission is under load.
• Intermittent gear slipping under heavy load: As the gear profile degrades, the transmission may momentarily lose torque transfer, causing sudden RPM spikes without corresponding vehicle speed increase.
• Metallic debris in transmission oil: Flaking or pitting on the gear flanks sheds ferrous particles into the lubricant, often visible during oil changes as silver or dark sludge.
• Vibration in neutral or low gear: Excessive wear on the gear’s bore or splines introduces radial play, transmitting vibration through the 0750117075: TAPER ROLLER BEARING that supports the shaft.

Technical Specifications

Compatibility

This gear is engineered exclusively for ZF WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It also fits select variants of the WG180 and WG200 when used with the 2095209019: DIFFERENTIAL assembly. Always confirm the gear’s spline count (21 internal splines) against your transmission’s intermediate shaft before installation. The 0631329086: SPRING PIN is required to secure the gear to the shaft during reassembly.
