Overview
The ZF 0750.117.346 TAPER ROLLER BEARING is a critical rotational support component engineered for the planetary gear sets within ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part (SKU: 0750.117.346) manages combined axial and radial loads, ensuring precise shaft alignment and smooth torque transfer under heavy-duty operating conditions. It is housed within the main gear cluster and works in conjunction with the 4143101009: HOUSING and the 4143301025: HOUSING to maintain structural integrity of the rotating assembly. Replacing this bearing with the exact OEM specification is essential to prevent premature wear on adjacent components.
Symptoms of Failure
- Growling or rumbling noise during gear engagement: A worn 0750.117.346 bearing produces a low-frequency growl that intensifies under load, often mistaken for gear noise. This indicates roller spalling or raceway pitting.
- Excessive end-play or shaft wobble: As the tapered rollers wear, axial clearance increases, causing the output shaft to wobble. This can lead to misalignment and accelerated wear on the 0634313603: O-RING and housing seals.
- Metallic debris in transmission fluid: Flaking of the bearing raceways introduces fine metallic particles into the oil. This contamination can clog the 4475280018: SCREW PLUG magnetic tip and damage downstream hydraulic circuits.
- Intermittent gear slippage under heavy load: Loss of bearing preload allows gear separation, causing momentary power loss. This symptom often precedes catastrophic bearing seizure.

Compatibility
This taper roller bearing is specifically designed for the ZF WG series powershift transmissions. Verified compatible models include the WG100, WG130, and WG131. It may also be applicable to the WG180 and WG200 series when used in the planetary carrier assembly, though cross-referencing with the parts manual is recommended. The bearing directly interfaces with the 4143101009: HOUSING and 4143301025: HOUSING to form the primary support structure for the input shaft.
