ZF 4699.302.216 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4699.302.216 SPUR GEAR is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This gear sits within the intermediate shaft assembly, where it transfers rotational torque from the input shaft to the output shaft via a constant-mesh helical design. As a critical element of the gear train, the 4699.302.216 ensures smooth power delivery and load distribution under heavy-duty industrial conditions. The part number 4699.302.216 is laser-etched for traceability and must be matched exactly during rebuilds to maintain factory tolerances. This spur gear works in concert with the 4699101071 HOUSING and the 4699301145 HOUSING to form a sealed, lubricated chamber that protects gear meshing from contamination.

Symptoms of Failure

• Whining or howling noise during acceleration: Worn gear teeth on the 4699.302.216 create uneven contact patterns, producing a distinct high-pitched whine that intensifies under load. This is a common long-tail search query for “ZF transmission whining noise when accelerating.”
• Metallic debris in transmission oil: As the spur gear surface spalls or pits, small metal particles contaminate the lubricant. Operators may notice glitter-like particles during oil changes, signaling imminent gear failure.
• Intermittent gear slipping under heavy torque: When the gear teeth lose their original profile, the transmission may momentarily lose engagement, causing a brief loss of drive power. This symptom often appears in “ZF WG100 gear slipping under load” searches.
• Vibration through the shift lever or chassis: A worn 4699.302.216 creates imbalance in the gear train, transmitting noticeable vibration at specific RPM ranges, particularly in the 1200–1800 RPM band.

Technical Specifications

Compatibility

This spur gear is specifically designed for the ZF WG100, WG130, and WG131 transmission models. It also fits select variants of the WG180 and WG200 series when used in the intermediate shaft position. Always verify the gear train configuration before installation. The 4699.302.216 is not compatible with WG210 or WG250 models without a full gear set replacement. For proper sealing, pair this gear with the 4699309085 HOUSING COVER and secure it using the 0636101411 CAP SCREW to prevent axial play.
