ZF 4699.302.246 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4699.302.246 SPUR GEAR is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This gear is responsible for transferring torque between parallel shafts within the countershaft assembly, directly influencing gear mesh stability and overall drivetrain efficiency. As a critical element in the power flow path, the SKU 4699.302.246 ensures correct tooth engagement and load distribution, reducing vibration and noise during operation. It is typically housed within the main transmission casing, adjacent to the 4699101086 HOUSING and the 4699301223 HOUSING, which provide structural support and alignment for the gear train.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn tooth profiles on the spur gear create irregular contact patterns, producing a distinct high-pitched sound that intensifies under load.
• Metal particles in transmission oil: Pitting or spalling on the gear teeth sheds metallic debris into the lubricant, often detected during routine oil changes or when inspecting the 0636302022 SCREW PLUG for contamination.
• Intermittent gear slipping or jumping: Excessive backlash from a worn 4699.302.246 spur gear causes momentary loss of torque transfer, particularly when shifting between higher gears.
• Vibration through the shift lever or chassis: Uneven wear on the gear teeth induces cyclical vibration, which can be felt during steady-state cruising and may worsen over time.

Technical Specifications

Compatibility

This spur gear is specifically designed for the ZF WG100, WG130, and WG131 mechanical transmissions. These models are commonly found in medium-duty commercial vehicles, agricultural tractors, and industrial material handling equipment. While the gear is not directly interchangeable with the WG180 or WG200 series due to different shaft center distances and tooth counts, it may share the same pitch diameter with select variants in the WG150 family. Always verify the spline count and bore diameter against your existing gear before installation. The 0501319149 SCREW PLUG is often replaced simultaneously to ensure proper sealing of the lubrication galleries adjacent to this gear.
