ZF 4699.197.031 ASSEMBLY PARTS | OEM Genuine Part

Overview

The ZF 4699.197.031 ASSEMBLY PARTS component is a precision-engineered internal sub-assembly designed for heavy-duty construction machinery transmissions. This OEM genuine part integrates directly into the clutch pack or planetary gearset housing, where it manages torque distribution and hydraulic pressure regulation. The SKU 4699.197.031 serves as a critical interface between the 4699100080: BASIC GEARBOX and the output shaft, ensuring seamless power transfer under extreme loads. When installed alongside a 0634309122: SHAFT SEAL, it prevents contamination ingress, while the 0634801038: SEALING RING maintains hydraulic integrity within the valve body.

Symptoms of Failure

• Erratic gear engagement under load: Worn assembly parts cause delayed or harsh shifting, especially when excavators or loaders operate on inclines.
• Hydraulic fluid seepage near the bell housing: Degraded sealing surfaces allow oil to escape, leaving visible drips on the transmission casing.
• Metallic grinding noise during deceleration: Internal bearing wear within the assembly produces a distinct whine or rattle when the vehicle coasts.
• Torque converter lock-up failure: The part’s inability to hold pressure leads to excessive slip and overheating in stop-and-go applications.

Technical Specifications

Compatibility

This assembly part is engineered for ZF WG-series transmissions commonly found in wheel loaders, graders, and telescopic handlers. It is directly compatible with the following models:

• ZF WG180 (all variants)
• ZF WG200 (including WG200/II)
• ZF WG210 (early production runs)
• ZF 4WG-200 (off-highway applications)

For proper installation, always pair this component with a new 0630000091: SHIM RING to maintain axial clearance. The 0634309122: SHAFT SEAL must be replaced concurrently to prevent premature wear.
