ZF 2098.328.016 FIXING BOLT | OEM Genuine Part

Overview

The ZF 2098.328.016 FIXING BOLT is a critical OEM genuine fastener engineered for secure mounting of transmission assemblies in heavy-duty construction machinery. This bolt ensures precise clamping force to maintain alignment between the transmission housing and the driveline components. The SKU 2098.328.016 is specifically designed to withstand high torsional loads and vibration common in off-road equipment. It sits at key junction points within the ZF powertrain, often securing the 2098117002: HOUSING to the main gearbox casing, preventing axial movement that could lead to misalignment.

Symptoms of Failure

• Oil seepage at bolt interface: A loose or fatigued fixing bolt can cause micro-gaps, leading to transmission fluid leaks around the 0634303044: O-RING sealing surfaces.
• Abnormal gear engagement noise: When the bolt loses torque, the 2098301052: REAR AXLE HOUS. may shift, producing clunking or grinding sounds during gear changes.
• Vibration under load: A broken or stripped fixing bolt allows the transmission housing to flex, causing noticeable vibration in the operator cab during heavy lifting or grading operations.
• Premature bearing wear: Insufficient bolt tension leads to housing distortion, accelerating wear on internal bearings and shafts.

Technical Specifications

Compatibility

This fixing bolt is designed for ZF transmissions commonly used in construction machinery, including the WG180, WG200, and WG310 series. It also fits select models of the ZF 4WG-200 and 5WG-300 power shift transmissions. The bolt is frequently paired with the 0636103300: STUD and 0637101164: HEXAGON NUT to secure the brake housing assembly. Always verify thread pitch and length against your specific transmission model before installation.
