Overview
The ZF 0501.335.216 HEXAGON NUT is a precision-engineered fastening component designed for critical load-bearing applications within ZF construction machinery transmissions. This OEM genuine part ensures secure clamping of internal gear assemblies and shaft components, maintaining the exact axial preload required for smooth power transfer. The SKU 0501.335.216 is specifically machined to withstand high vibration and torque loads found in heavy-duty environments. When installed alongside the 4699101108: HOUSING, this hexagon nut locks the drivetrain assembly in place, preventing rotational play that could lead to premature wear.
Symptoms of Failure
- Transmission gear slipping under load: A loose or worn hexagon nut can cause axial shaft movement, resulting in intermittent gear disengagement during operation.
- Abnormal metallic rattling from the transmission housing: When the 0501.335.216 loses its clamping force, internal components may vibrate against the 4699102172: INPUT shaft assembly.
- Oil seepage at the output flange: Insufficient nut torque can distort the 4699103057: OUTPUT seal surface, causing gradual hydraulic fluid loss.
- Increased backlash in the final drive: Worn threads on this hexagon nut allow cumulative play between the 4699001185: GK10LD gear set and the main shaft.

Compatibility
This hexagon nut is a standard fastening element used across multiple ZF transmission platforms for construction machinery. It is directly compatible with the WG180, WG200, and WG250 series transmissions. Additionally, it appears in the ZF 4WG-200 and ZF 5WG-200 models where it secures the sun gear shaft to the planetary carrier. Always verify thread pitch and seating surface condition when replacing this nut in older WG160 variants.
