ZF 2093.109.002 DIFFERENTIAL | OEM Genuine Part

Overview

The ZF 2093.109.002 DIFFERENTIAL is a critical torque-distributing assembly within the final drive of heavy-duty construction machinery transmissions. Positioned between the ring gear and the axle shafts, this OEM genuine part ensures that rotational power is split evenly between the left and right wheels, allowing for smooth cornering and reduced tire scrub on uneven terrain. The SKU 2093.109.002 is engineered to handle extreme axial and radial loads, making it a direct replacement for worn units in ZF drivelines. When servicing this assembly, it is common to inspect the 2093209095 DIFFERENTIAL for matching wear patterns, as both components share the same load path.

Symptoms of Failure

• Whining or howling noise during turns: A worn differential gear set produces a distinct metallic whine when the vehicle corners, indicating excessive backlash or pitting on the gear teeth.
• Oil leaks around the axle housing: Deteriorated seals or a cracked 2093309071 DIFF.HOUSING allow gear oil to escape, leading to low lubricant levels and accelerated internal wear.
• Vibration under load: Worn 0750117075 TAPER ROLLER BEARING sets cause the differential carrier to wobble, transmitting vibration through the chassis during acceleration or heavy pulling.
• Intermittent wheel lock-up or slipping: A seized 0631100223 SPRING PIN can prevent the differential from releasing, causing one wheel to drag or spin erratically on loose surfaces.

Technical Specifications

Compatibility

This differential is designed for ZF heavy-duty powershift transmissions commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the following ZF transmission models: WG180, WG200, WG210, and WG220 series. The unit also integrates with the 2097309085 DIFFERENTIAL AXLE and the 4482360002 AXLE BEVEL GEAR for complete final drive refurbishment. Always verify the axle housing casting number against the 2093309049 SLEEVE dimensions to ensure proper spline engagement.

Frequently Asked Questions

Q: How do I know if the 2093.109.002 differential is compatible with my ZF WG200 transmission?
A: This part is a direct OEM replacement for the WG200 series. Check the spline count on your existing unit; the 2093.109.002 uses a 16-spline input. For confirmation, measure the bearing journal diameter against the 0750117075 TAPER ROLLER BEARING specifications.

Q: Can I replace just the differential without replacing the housing?
A: Yes, but only if the 2093309071 DIFF.HOUSING shows no cracks or scoring. Always inspect the thrust washers (0730300820 and 5838300811) for wear during reassembly.

Q: What causes premature failure of the 2093.109.002 differential?
A: The most common cause is low gear oil level or contamination from metal debris. A seized 0631100223 SPRING PIN can also lock the spider gears, leading to rapid tooth wear. Regular oil changes every 500 hours are recommended.
