Overview
The ZF 2099.364.014 CROWN WHEEL is a critical hypoid gear component engineered for heavy-duty construction machinery transmissions. This OEM genuine part transfers rotational torque from the pinion shaft to the differential assembly, enabling final drive reduction and power distribution to the axles. Positioned within the axle housing, the crown wheel meshes directly with the pinion gear to convert high-speed input into the low-speed, high-torque output required for earthmoving and material handling equipment. The SKU 2099.364.014 is precision-machined to OEM tolerances, ensuring silent operation and extended service life under extreme loads. This crown wheel works in concert with the 2099109002 DIFFERENTIAL and 2099209001 DIFFERENTIAL to form the core of the final drive assembly.
Symptoms of Failure
- Whining or howling noise from the axle housing: Worn gear teeth on the crown wheel produce a distinct high-pitched whine during acceleration or deceleration, often misdiagnosed as wheel bearing failure.
- Metallic debris in transmission oil: Flaking or pitting of the crown wheel surface introduces ferrous particles into the lubricant, visible during oil changes or magnetic drain plug inspection.
- Backlash increase and driveline clunk: Excessive clearance between the crown wheel and pinion gear causes a noticeable clunk when shifting between forward and reverse, indicating advanced wear.
- Vibration under load: Uneven tooth wear creates cyclic vibration felt through the chassis during digging or pushing operations, signaling imminent gear failure.

Compatibility
This crown wheel is designed for ZF heavy-duty powershift transmissions used in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series, commonly found in wheel loaders, graders, and dump trucks. The 2099.364.014 also integrates with the 2098309010 DIFFERENTIAL HOUSING and 2098309009 DIFFERENTIAL HOUSING to ensure proper gear alignment. For complete axle rebuilds, pair this crown wheel with the 2098309031 AXLE BEVEL GEAR and 2098309030 AXLE BEVEL GEAR to restore factory gear mesh patterns.
