ZF 0737.502.192 SLOTTED NUT | OEM Genuine Part

Overview

The ZF 0737.502.192 SLOTTED NUT is a precision-engineered fastening component designed to secure critical rotating assemblies within heavy-duty ZF transmissions. This OEM genuine part functions as a locking mechanism on shaft ends, ensuring that gears, bearings, and differential components maintain their correct axial position under extreme torque loads. Commonly found in construction machinery transmissions, the 0737.502.192 slotted nut works in concert with cotter pins or locking tabs to prevent loosening from vibration. When paired with a 2099109002: DIFFERENTIAL or a 2099364014: CROWN WHEEL, this nut provides the clamping force necessary for reliable power transfer. The SKU 0737.502.192 is a direct OEM replacement, guaranteeing exact thread pitch and hardness specifications for ZF drivetrains.

Symptoms of Failure

When the ZF 0737.502.192 slotted nut wears or loosens, operators may notice several distinct failure indicators. Transmission oil leaks at the output shaft seal often occur because axial play allows the seal lip to lose contact with the shaft surface. Intermittent gear slipping under load is another common symptom, as insufficient clamping force permits the 2099209001: DIFFERENTIAL to shift position. Abnormal clunking or knocking noises during acceleration or deceleration indicate that the nut has backed off, creating clearance between mating gears. Finally, premature bearing failure can result from the loss of preload, leading to excessive radial and axial movement within the transmission housing.

Technical Specifications

Compatibility

This slotted nut is engineered for ZF heavy-duty transmissions commonly installed in construction machinery, including wheel loaders, excavators, and telehandlers. It is compatible with the ZF WG180, WG200, and WG310 series transmissions. The 0737.502.192 nut is also used in ZF TC-Tronic and Ergopower drivelines where it secures the differential pinion shaft. For proper assembly, this nut should be torqued to 250 Nm and locked with a cotter pin through the 2098309010: DIFFERENTIAL HOUSING to ensure long-term retention in high-vibration environments.
