Overview
The ZF 2093.311.019 RING GEAR is a critical component within the final drive assembly of WG100, WG130, and WG131 transmissions. This OEM genuine part transfers torque from the differential case to the axle shafts, enabling smooth power delivery and load distribution. The ring gear meshes directly with the pinion gear to achieve the final gear reduction, making it essential for vehicle traction and driveline efficiency. The SKU 2093.311.019 is precision-machined to OEM tolerances, ensuring a direct fit and long service life in heavy-duty applications.
Symptoms of Failure
When the ZF 2093.311.019 ring gear wears out, operators often notice distinct operational issues. Whining or howling noise during acceleration typically indicates uneven tooth wear or pitting on the gear surface. Vibration in the driveline under load suggests the ring gear has developed backlash issues or tooth chipping. Metal particles in the transmission fluid are a clear sign of gear degradation, often accompanied by intermittent gear slipping or loss of power to the wheels. These symptoms worsen over time and require immediate inspection to prevent secondary damage to the differential assembly.

Compatibility
This ring gear is specifically engineered for ZF WG100, WG130, and WG131 transmission models. It is also compatible with select WG180 and WG200 variants that share the same final drive architecture. The part integrates directly with the 2093109024 DIFFERENTIAL and the 2093209095 DIFFERENTIAL assemblies. For proper installation, it must be paired with the 0750117075 TAPER ROLLER BEARING and the 2093309071 DIFF.HOUSING to ensure correct alignment and load support.

Frequently Asked Questions
Q: Can the 2093.311.019 ring gear be installed without replacing the differential bearings?
A: It is strongly recommended to replace the 0750117075 TAPER ROLLER BEARING simultaneously, as worn bearings accelerate ring gear wear and cause misalignment.
Q: How do I identify if my WG100 transmission uses this specific ring gear?
A: Check the transmission serial number and final drive ratio. The 2093.311.019 is standard for 37-tooth configurations. Cross-reference with the 2093309071 DIFF.HOUSING to confirm compatibility.
Q: What torque specification is required for the ring gear bolts?
A: OEM specification is 120 Nm (88.5 lb-ft) for M10 bolts, applied in a cross-pattern sequence. Always use new 0631100223 SPRING PIN fasteners during reinstallation.
