Overview
The ZF 0750.117.789 TAPERED ROLLER BEARING is a critical load-bearing component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part sits directly on the main shaft assembly, where it manages axial and radial loads generated during gear engagement and torque transfer. Designed to reduce friction and maintain precise shaft alignment, the 0750.117.789 bearing ensures smooth rotational motion and extends the service life of the entire drivetrain. When paired with a 2094104412 MAIN SHAFT or a 2094304054 MAIN SHAFT, this bearing provides the foundational support necessary for reliable power delivery in heavy-duty applications.
Symptoms of Failure
When the 0750.117.789 tapered roller bearing begins to fail, operators may notice a distinct grinding or rumbling noise from the transmission housing, especially during acceleration or deceleration. Another common symptom is excessive axial play in the main shaft, which can lead to gear misalignment and difficult shifting. Over time, worn bearings can cause metallic debris to contaminate the transmission oil, resulting in poor lubrication and eventual gear slipping. If left unaddressed, these issues may escalate into complete bearing seizure, damaging the 2094106010 SHIFT SYSTEM and surrounding components.

Compatibility
This tapered roller bearing 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 main shaft geometry. Always verify your transmission serial number before ordering to ensure correct fitment. For transmissions using a 2094206001 GEARSHIFT SHAFT, this bearing serves as a direct replacement for the original factory component.

Frequently Asked Questions
Q: How do I know if the 0750.117.789 bearing is the correct replacement for my transmission?
A: Check your transmission model number—this bearing is designed for WG100, WG130, and WG131 series. If you have a WG180 or WG200, verify the main shaft diameter matches 35 mm ID before purchasing.
Q: Can I replace this bearing without removing the main shaft?
A: No. The tapered roller bearing is press-fit onto the main shaft. You must remove the 2094104412 MAIN SHAFT or 2094304054 MAIN SHAFT to access and replace the bearing properly.
Q: What other parts should I replace when installing this bearing?
A: It is recommended to replace the 0630513070 SNAP RING and 2094306019 WASHER at the same time to ensure proper preload and prevent premature wear.
