ZF 4699.372.044 SEGMENT | OEM Genuine Part

Overview

The ZF 4699.372.044 SEGMENT is a precision-engineered internal component designed for heavy-duty construction machinery transmissions. This OEM genuine part functions as a critical alignment and load-distribution element within the planetary gear set, ensuring smooth torque transfer and reducing mechanical stress on adjacent assemblies. As a segmented component, it interfaces directly with the transmission housing and clutch pack, maintaining proper gear spacing under high-load conditions. The SKU 4699.372.044 is manufactured to ZF’s exacting tolerances, making it essential for restoring factory performance in worn transmissions. When installed alongside the 4699101045 HOUSING, this segment helps maintain structural integrity in the gear train.

Symptoms of Failure

• Intermittent gear slipping under load: A worn 4699.372.044 segment can cause the planetary gears to lose proper alignment, leading to sudden power loss during excavation or grading operations.
• Metallic grinding noise from transmission: When the segment’s contact surfaces degrade, you may hear a distinct grinding sound, especially when shifting between forward and reverse gears in construction machinery.
• Oil contamination with metal particles: As the segment wears, microscopic metal shavings can enter the transmission fluid, visible during routine oil changes as a glittery or dark residue.
• Increased vibration during operation: A failing segment disrupts the balanced rotation of the gear set, causing noticeable chassis vibration at specific RPM ranges in wheel loaders or dozers.

Technical Specifications

Compatibility

This segment is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180 and WG200 models, as well as the heavy-duty WG210 series used in articulated dump trucks and large wheel loaders. The part also applies to select WG150 variants where the planetary gear set shares identical spacing. For proper installation, ensure the mating 4699301108 HOUSING and 4699301085 COVER are free of scoring or deformation. Additionally, the 4699301014 THREAD PROTECTIVE SHIELD should be inspected for thread damage during reassembly.
