Overview
The ZF 5838.300.824 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 transmits rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. As a critical element in the gear train, the 5838.300.824 spur gear maintains correct gear mesh alignment and reduces drivetrain vibration. When paired with a DIFFERENTIAL (5838109021), this gear forms the core of the final drive reduction. The SKU 5838.300.824 is manufactured to ZF’s original specifications, guaranteeing exact fitment and wear resistance in demanding industrial applications.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn 5838.300.824 spur gear produces a distinct high-pitched whine, especially when the transmission is under load. This indicates pitting or tooth surface fatigue.
- Intermittent gear slipping in auxiliary drive: If the spur gear teeth have chipped or worn unevenly, the transmission may momentarily lose power delivery to the PTO, causing erratic operation.
- Metallic debris in transmission oil: Flakes or silver particles in the fluid often originate from a failing spur gear. This symptom typically accompanies increased backlash between the gear and the DIFFERENTIAL (2095209019).
- Vibration through the gearshift lever: Excessive radial play in the spur gear bearing seat creates noticeable vibration, which can accelerate wear on the TAPER ROLLER BEARING (0750117075).

Compatibility
This ZF 5838.300.824 spur gear is specifically engineered for the WG100, WG130, and WG131 transmission series. These models are commonly found in medium-duty trucks, agricultural tractors, and construction loaders. The gear also fits select variants of the WG180 and WG200 transmissions when used with the correct SPRING PIN (0631329086) for shaft retention. Always verify the transmission serial number against ZF’s parts catalog, as the gear’s spline profile differs between early and late production units. For WG151 and WG250 models, consult your OEM dealer before installation.
