ZF 0735.372.036 TAPERED ROLLER BEARING for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0735.372.036 TAPERED ROLLER BEARING is a precision-engineered component designed to manage axial and radial loads within the planetary gear sets of ZF WG series transmissions. Positioned inside the main housing assembly, this OEM genuine part ensures smooth rotation of the countershaft and differential pinions under high torque conditions. The SKU 0735.372.036 is manufactured to ZF’s exacting tolerances, providing a direct replacement that maintains factory-specified gear mesh alignment and reduces frictional heat buildup during prolonged operation.

Symptoms of Failure

• Growling or rumbling noise from the transmission housing – A worn 0735.372.036 bearing often produces a low-frequency growl that intensifies under load, especially during acceleration or deceleration.
• Excessive end-play in the output shaft – As the tapered rollers lose their preload, detectable axial movement at the flange indicates the bearing is no longer supporting the shaft correctly.
• Metallic debris in the transmission fluid – Flaking or spalling of the bearing raceways introduces fine steel particles into the oil, which can be observed during routine drain intervals.
• Intermittent gear engagement hesitation – When the bearing fails, the resulting misalignment can cause delayed or rough shifting between forward and reverse gears.

Technical Specifications

Compatibility

This tapered roller bearing is specifically engineered for ZF WG100, WG130, and WG131 transmissions. It is also commonly used in the WG180 and WG200 series where the countershaft bearing arrangement matches the same bore and width dimensions. Always verify the bearing cavity dimensions in your transmission before installation, as some WG200 variants may use a different cage design.

When replacing the 0735.372.036, it is critical to inspect the surrounding 4143101022 HOUSING and 4143301044 HOUSING for wear or scoring. The bearing is secured in place using a 0631329135 SPRING PIN that locks the outer race, while the 0636302014 SCREW PLUG seals the lubrication gallery feeding the bearing. For a complete overhaul, also consider the 0634801057 SEALING RING and 4143301053 CONNECTING PART to ensure leak-free operation.
