Overview
The ZF 0735.371.759 TAPER ROLLER BEARING is a precision-engineered component designed to manage axial and radial loads within the planetary gear sets of ZF WG190 and WG210 series transmissions. This OEM genuine part ensures smooth rotational motion and maintains critical gear alignment under heavy torque conditions. The SKU 0735.371.759 is specifically positioned in the output shaft assembly, where it supports the sun gear and differential carrier. Without this bearing, the transmission cannot maintain proper gear mesh, leading to accelerated wear on surrounding components such as the TRANSMISSION HOUSING and the HOUS.FRONT SECT.
Symptoms of Failure
- Growling or rumbling noise during acceleration: When the tapered rollers or raceways become pitted or spalled, a low-frequency growl emanates from the transmission, particularly under load. This is a classic sign that the 0735.371.759 bearing has exceeded its service life.
- Intermittent gear slipping or delayed engagement: Worn rollers allow excessive axial play, causing the planetary gears to lose proper alignment. Operators may notice hesitation when shifting between forward and reverse ranges.
- Metallic debris in transmission fluid: Flaking or chipping of the bearing surfaces introduces fine steel particles into the oil. This contamination can clog the SCREEN SHEET (part 4657301034) and accelerate wear on the HOUSING REAR PART.
- Oil leaks near the output flange: As the bearing cage degrades, it can shift the shaft alignment, compromising the seal contact area. This often results in fluid weeping around the rear housing joint.

Compatibility
This taper roller bearing is engineered for ZF WG-series transmissions with a torque capacity between 190 and 210 Nm. It is a direct fit for the WG 190 Series and WG 210 Series gearboxes. While primarily designed for these two families, the 0735.371.759 may also be used in select WG180 and WG200 variants that share the same output shaft geometry. Always verify the bearing seat dimensions in the TRANSMISSION HOUSING before installation. The bearing is secured in place using a CYLINDRICAL PIN (part 0631306792) that aligns the outer race with the housing bore.

Frequently Asked Questions
Q: How do I know if the 0735.371.759 bearing is the correct replacement for my WG210 transmission?
A: Check the part number stamped on the outer race of your existing bearing. If it matches 0735.371.759, it is a direct OEM replacement. Additionally, measure the bore diameter of the TRANSMISSION HOUSING to confirm it is 85 mm.
Q: Can I reuse the old CYLINDRICAL PIN (0631306792) when installing this bearing?
A: No. The pin can become deformed during removal. Always install a new CYLINDRICAL PIN to ensure the bearing race is correctly aligned with the housing bore.
Q: What torque specification should I use for the CAP SCREWS that secure the bearing retainer?
A: For the CAP SCREW (part 0636100801), apply 45 Nm. Over-tightening can distort the bearing race and cause premature failure.
