ZF 4699.008.047 GK16 | OEM Genuine Part

Overview

The ZF 4699.008.047 GK16 is a critical OEM genuine component engineered for the high-stress environment of construction machinery transmissions. This part functions as a precision-machined gear or shaft assembly within the planetary gear set, directly influencing torque distribution and rotational stability. Specifically, the SKU 4699.008.047 interfaces with the main drive housing to ensure synchronized power flow from the input shaft to the output shaft. Without this component, the transmission cannot maintain proper gear engagement under heavy loads. It is commonly sourced for rebuilds of ZF power shift transmissions used in wheel loaders, dozers, and graders.

Symptoms of Failure

• Intermittent gear slipping under load: When the 4699.008.047 wears, the transmission may momentarily lose torque transfer during acceleration, particularly in lower gears.
• Metallic grinding noise from the bell housing: A distinct whining or grinding sound, especially when shifting between forward and reverse, indicates bearing surface degradation on this part.
• Contaminated transmission fluid with metallic debris: Worn splines or gear teeth shed fine metal particles, visible during oil changes as a silver or copper sheen in the fluid.
• Delayed engagement or harsh shifting: The transmission may hesitate before engaging a gear or slam into gear due to improper clearance caused by a worn GK16 assembly.

Technical Specifications

Compatibility

This OEM genuine part is designed for use in ZF WG series transmissions commonly deployed in construction machinery. It is a direct fit for the WG180, WG200, and WG210 models. The 4699.008.047 also appears in select ZF 4WG-200 and ZF 6WG-250 variants used in articulated dump trucks and crawler loaders. Always verify your transmission serial number against the OEM parts catalog before ordering.

During installation, this GK16 assembly mates directly with the 4699101093 HOUSING and the 4699102142 INPUT shaft. The 4699103054 OUTPUT shaft provides the final torque transfer, while the 4699105072 HOUSING TOP PART encloses the assembly. For a complete rebuild, inspect the 0634303936 O-RING and 0750110302 SHAFT SEAL for wear.
