ZF 0737.300.151 HEXAGON NUT | OEM Genuine Part

Overview

The ZF 0737.300.151 HEXAGON NUT is a critical fastening component engineered for secure retention within heavy-duty ZF transmission assemblies. This OEM genuine part ensures precise clamping force on internal shafts and gear trains, preventing axial displacement during high-torque operations. Commonly found in construction machinery transmissions, the SKU 0737.300.151 directly interfaces with the 4699101086: HOUSING and the 4699301223: HOUSING to maintain structural integrity under extreme loads. Without this hexagon nut, gear alignment and torque transfer become compromised, leading to cascading mechanical failures.

Symptoms of Failure

• Transmission oil seepage at housing joints: A loosened 0737.300.151 nut can create micro-gaps between mating surfaces, allowing hydraulic fluid to escape past the 0636302022: SCREW PLUG and 0501319149: SCREW PLUG interfaces.
• Audible gear rattle or clunking during shifts: Worn hexagon nut threads reduce preload on shaft bearings, causing gear train backlash that produces metallic knocking sounds.
• Progressive gear slippage under load: Inadequate nut torque allows internal components to shift, resulting in intermittent power loss during excavation or lifting operations.
• Vibration through the driveline: A failing nut permits rotational imbalance, transmitting harsh oscillations to the chassis at specific RPM ranges.

Technical Specifications

Compatibility

This hexagon nut is designed for integration into ZF WG-series transmissions commonly deployed in construction machinery. Verified compatible models include the ZF WG180, WG200, and WG210 series. It also appears in select ZF 4WG-310 and 5WG-200 torque converter transmissions. Always cross-reference the 0730365801: TYPE PLATE to confirm exact fitment for your specific assembly.
