ZF 4699.805.013 GK30 | OEM Genuine Part

Overview

The ZF 4699.805.013 GK30 is a genuine OEM gear set assembly engineered for heavy-duty construction machinery transmissions. This critical component sits within the planetary gear train, managing torque distribution and rotational speed between the input shaft and the output drive. As a precision-machined assembly, the SKU 4699.805.013 ensures seamless power transfer under extreme loads, directly influencing machine productivity. When paired with the 4699101044 HOUSING and the 4699301111 HOUSING, this part forms the core of the transmission’s load-bearing structure, guaranteeing alignment and durability in demanding environments like excavators and wheel loaders.

Symptoms of Failure

When the ZF 4699.805.013 GK30 wears out, operators often notice distinct performance declines. Gear slipping under load is a primary indicator, where the transmission hesitates or loses drive during heavy excavation. Metallic grinding noises from the gearbox signal tooth surface fatigue or pitting, especially during shifts. Oil contamination with metallic debris in the hydraulic fluid points to accelerated wear of the gear set. Additionally, erratic shifting patterns or delayed engagement can occur as the GK30 loses its precise meshing capability, directly impacting machine cycle times.

Technical Specifications

Compatibility

This genuine ZF 4699.805.013 GK30 is designed for integration into ZF WG series transmissions commonly found in construction machinery. It is directly compatible with the WG180, WG200, and WG210 models, which power articulated dump trucks, graders, and compact loaders. The gear set also fits select WG160 and WG250 variants when used with the 4699301054 HOUSING COVER and 4699301055 COVER for proper sealing. Always verify your transmission serial number to ensure exact fitment.
