Overview
The ZF 0750.117.636 SPHERICAL ROLLER BEARING is a critical load-bearing component engineered for the planetary gear sets and main shaft assemblies within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part ensures precise rotational alignment and absorbs both radial and axial forces generated during high-torque operations. The SKU 0750.117.636 is specifically designed to maintain gear mesh integrity, reducing vibration and extending the service life of the entire drivetrain. It sits directly within the transmission housing, supporting the output shaft and interacting with the 4108101115 HOUSING and 4108201277 HOUSING to form a sealed, durable bearing chamber.
Symptoms of Failure
- Growling or rumbling noise during gear shifts: Worn spherical rollers create uneven contact, producing a low-frequency growl that intensifies under load, often mistaken for gear wear.
- Transmission oil leaks near the bearing cover: As the bearing degrades, it can misalign the 4108301304 BEARING COVER, allowing fluid to escape past the shaft seal.
- Excessive axial play in the output shaft: A failing 0750.117.636 bearing permits lateral movement, causing erratic shifting and delayed engagement in forward or reverse gears.
- Metallic debris in the oil pan: Spalling of the roller surfaces releases fine steel particles, which can clog the 0501313402 DRAIN VALVE and accelerate wear on adjacent components.

Compatibility
This spherical roller bearing is a direct OEM replacement for the following ZF transmission models: WG100, WG130, and WG131. It is also compatible with select variants of the WG180 and WG200 series when used in the main shaft support position. Always verify the housing bore dimensions against your specific transmission serial number before installation. The bearing works in conjunction with the 4108111051 POWER TAKE-OFF assembly and requires proper shimming using 0730106757 WASHER, 0730106758 WASHER, or 0730106759 WASHER to achieve correct preload.
