ZF 5838.200.004 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 5838.200.004 SPUR GEAR is a precision-engineered component designed for the auxiliary drive and power take-off (PTO) systems within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. As a critical element of the gear train, the 5838.200.004 spur gear directly influences shift quality and overall driveline efficiency. When replacing this gear, it is essential to inspect the mating 5838109007: DIFFERENTIAL for wear, as both components share a constant load interface.

Symptoms of Failure

• Whining or grinding noise during acceleration: Worn gear teeth produce a high-pitched whine that intensifies under load, often indicating pitting or chipping on the spur gear surface.
• Intermittent gear slipping in WG100/WG130: A failing 5838.200.004 can cause the transmission to momentarily lose power delivery, especially when engaging the PTO or shifting between forward gears.
• Metal particles in transmission fluid: Flaking or spalling from the spur gear contaminates the oil, which may also affect the 0750117075: TAPER ROLLER BEARING and other rotating assemblies.
• Hard shifting or delayed engagement: Excessive backlash from a worn gear creates hesitation when the transmission attempts to lock into gear, often accompanied by a clunk sound.

Technical Specifications

Compatibility

This spur gear is engineered specifically for ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in auxiliary drive positions. For proper installation, always replace the 2095209019: DIFFERENTIAL and the 0631329086: SPRING PIN simultaneously to maintain correct gear mesh alignment. The 5838.200.004 is not interchangeable with older ZF 5-speed or 6-speed manual transmission gears.
