Overview
The ZF 4699.302.244 SPUR GEAR is a precision-machined helical gear designed for the auxiliary drive train within ZF WG100, WG130, and WG131 series transmissions. This OEM genuine part transmits torque from the input shaft to the countershaft, directly influencing gear engagement stability and overall driveline efficiency. The SKU 4699.302.244 is manufactured to ZF’s original tolerances, ensuring a direct fit without modification. It sits within the main gear cluster, meshing with adjacent shafts to maintain synchronized rotation under heavy load conditions.
Symptoms of Failure
- Whining or grinding noise during gear engagement – Worn tooth profiles on the 4699.302.244 produce a high-pitched metallic sound, especially when shifting under load. This often indicates pitting or spalling on the gear face.
- Intermittent gear slipping under torque – As the spur gear loses tooth height or develops micro-cracks, the transmission may momentarily lose power transfer, causing a sudden RPM surge without acceleration.
- Metallic debris in transmission oil – Flakes or fine silver particles found during oil changes point to surface fatigue on the 4699.302.244 gear teeth, accelerating wear on mating components.
- Hard shifting or gear lockout – Damaged gear teeth prevent smooth sliding engagement, requiring excessive force to move the shift lever or causing complete refusal to enter a gear.

Compatibility
This spur gear is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in the auxiliary drive position. The 4699.302.244 replaces earlier revisions (4699.302.241 and 4699.302.242) and is backward-compatible with all housings that accept the 35 mm bore shaft. Always verify the gear stack height against your transmission’s service manual before installation.
During rebuild, this gear is typically installed alongside the 4699101086 HOUSING and the 4699301223 HOUSING, which enclose the gear cluster. The 0636302022 SCREW PLUG and 0501319149 SCREW PLUG seal the lubrication passages feeding this gear. For a complete overhaul, inspect the 0634801038 SEALING RING and 0501323165 SHAFT SEAL to prevent oil bypass.
