Overview
The ZF 0736.029.001 ANTI-FATIGUE BOLT is a critical fastening component engineered specifically for the WG 200 Series transmission. This OEM genuine part, identified by SKU 0736.029.001, is designed to secure the 4460115043: HOUSING assembly within the transmission’s main casing. Its primary function is to withstand cyclic loading and vibration, preventing loosening over extended operational periods. By maintaining consistent clamping force, this bolt ensures that the housing remains properly aligned, which is essential for optimal gear mesh and overall drivetrain reliability. The anti-fatigue design reduces stress risers, making it a durable choice for heavy-duty industrial applications.
Symptoms of Failure
When the 0736.029.001 anti-fatigue bolt begins to wear or fatigue, operators may notice several distinct failure indicators. Look for these long-tail search queries to identify issues early:
- Transmission oil seepage at housing joints: A loose or fatigued bolt can compromise the seal between the housing and the 4469315012: AXLE DRIVE HOUSING, leading to fluid migration.
- Abnormal gear whine or vibration during load: Insufficient clamping force allows micro-movement, causing misalignment and audible noise.
- Recurring bolt loosening after service intervals: If the bolt fails to maintain torque, it may indicate material fatigue or thread deformation.
- Visible corrosion or thread galling: Exposure to heat and contaminants can degrade the bolt surface, accelerating failure.

Compatibility
This anti-fatigue bolt is primarily designed for the ZF WG 200 Series transmission family. It is directly compatible with models including the WG180, WG200, and WG210. The bolt is also used in select variants of the ZF WG 150 Series where similar housing configurations exist. For precise fitment, always verify the part number against your transmission’s service manual. When replacing this bolt, it is recommended to also inspect the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING for wear, as these components share the same load path.
