Overview
This genuine ZF 0735.330.925 angular ball bearing is a precision-engineered component designed specifically for the WG160 transmission series and its derivatives. Positioned within the main shaft assembly, this bearing manages combined axial and radial loads, ensuring smooth rotational motion and precise gear alignment under high torque conditions. The SKU 0735.330.925 is manufactured to OEM tolerances, guaranteeing a direct fit and long service life when paired with the 4656101037: TRANSMISSION HOUSING and the 4656201075: HOUS.FRONT SECT. Replacing a worn bearing with this OEM part restores drivetrain efficiency and prevents cascading damage to adjacent components.
Symptoms of Failure
- Whining or grinding noise during gear shifts: A failing angular ball bearing produces a distinct metallic whine or grinding sound, especially when the transmission is under load or during deceleration.
- Excessive axial shaft play: Wear in the bearing raceways allows the main shaft to move laterally, causing imprecise gear engagement and difficulty selecting gears.
- Oil contamination with metallic debris: As the bearing degrades, fine metal particles enter the transmission fluid, often visible during oil changes or as sludge on the 4656301016: SCREEN SHEET.
- Vibration through the gear lever or chassis: Unbalanced rotation from a damaged bearing transmits vibration throughout the driveline, worsening at higher RPMs.

Compatibility
This bearing is engineered for the ZF WG160 series and is also compatible with the WG 190, WG 191, WG 210, WG 211, and WG 230 transmission families. It directly replaces the original bearing in the main shaft support position. For proper installation, ensure the 4656201035: HOUSING REAR PART and the 4472239178: HOUSING REAR PART are free of scoring or wear. This bearing is not interchangeable with standard deep-groove ball bearings due to its specific contact angle.

Frequently Asked Questions
Q: Can I use this bearing in a WG180 transmission?
A: The 0735.330.925 is not listed for WG180 models. It is designed for WG160 through WG230 series. Always verify your transmission’s serial number against the OEM parts catalog.
Q: How do I confirm the correct orientation during installation?
A: The angular contact bearing has a marked load direction. The thicker outer ring shoulder must face the axial load source (typically toward the gear). Refer to the ZF service manual for your specific WG model.
Q: Is this bearing supplied with a new seal or snap ring?
A: No. The bearing is supplied as a standalone component. You will need to reuse or replace the associated snap ring and seal separately. Check the condition of the 4656301148: FIXING PLATE during reassembly.
