ZF 4699.801.262 GK10 | OEM Genuine Part

Overview

The ZF 4699.801.262 GK10 is a genuine OEM gearshift assembly designed for heavy-duty construction machinery transmissions. This part functions as the primary mechanical interface between the shift lever and the internal clutch pack, ensuring precise gear engagement under high-torque loads. The SKU 4699.801.262 is a direct replacement for the original GK10 unit, manufactured to ZF’s exact tolerances for durability in excavators, wheel loaders, and graders. It sits within the transmission control housing, where it converts linear input into rotational motion to actuate the shift fork. For complete assembly, this part is often paired with the 4699001200: GK10 base unit and the 4699101125: HOUSING that encloses the mechanism.

Symptoms of Failure

• Hard shifting or gear engagement delay: Worn internal detents or springs cause the operator to force the lever, leading to missed shifts.
• Transmission oil leaks at the shift tower: Degraded seals around the GK10 allow hydraulic fluid to seep past the 0634306309: O-RING, leaving puddles under the machine.
• Intermittent neutral position drift: A worn shift gate fails to lock the lever in neutral, causing unintended vehicle movement during startup.
• Excessive play in the shift lever: Bushing wear inside the assembly creates a sloppy feel, reducing operator control precision.

Technical Specifications

Compatibility

This genuine GK10 part is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It directly fits the WG180, WG200, and WG250 models. The assembly also integrates with the 4699102154: INPUT shaft and the 4699103016: OUTPUT flange. Always verify your transmission serial number before ordering, as variations exist in early WG180 units.
