ZF 2099.310.014 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2099.310.014 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and PTO (Power Take-Off) interface within ZF WG100, WG130, and WG131 transmission assemblies. This OEM genuine part transfers rotational force from the countershaft to the output drive, ensuring synchronized gear engagement under heavy load conditions. The SKU 2099.310.014 is manufactured to ZF’s original tolerances, featuring case-hardened alloy steel for extended service life in off-highway and industrial applications. When installed alongside the TRANSMISSION HOUSING (2094101017), this spur gear maintains precise axial alignment critical for torque distribution.

Symptoms of Failure

• Whining or howling noise during PTO engagement — Worn gear teeth produce a distinct metallic whine under load, often mistaken for bearing failure. This symptom typically worsens when the transmission reaches operating temperature.
• Intermittent power loss to auxiliary equipment — A chipped or spalled tooth on the 2099.310.014 spur gear causes erratic torque delivery, leading to hydraulic pump or winch underperformance.
• Metal debris in transmission oil filter — Flaking from the gear’s hardened surface contaminates the lubricant, often visible as silver particles during routine oil changes. This accelerates wear on the HOUSING (2094301069) and adjacent bearings.
• Vibration at idle or low RPM — Uneven tooth wear creates harmonic imbalance, felt through the gearshift lever or chassis mounts. This is a common long-tail search query for “ZF transmission vibration when idling.”

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF’s WG-series industrial transmissions, including the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 variants when used in auxiliary drive configurations. The gear interfaces directly with the HOUSING (2094298054) and requires the SCREW PLUG (0636302008) for proper lubrication retention. Always verify your transmission’s serial number before ordering.
