Woodruff Key 3x3.7mm for KTM, Husqvarna & GasGas 2003-2026 - 0888030037

This genuine OEM Woodruff Key (DIN6888-3X3.7) is a critical mechanical component used to lock rotating elements securely onto shafts. It ensures precise alignment and prevents slippage between the crankshaft, balancer shaft, or ignition rotor and their respective gears or flywheels. As an original equipment manufacturer part, it guarantees the exact tolerances and material strength required for high-performance motorcycle engines.

This part fits an extensive range of motorcycles across the KTM, Husqvarna, and GasGas lineups from 2003 to 2026. Compatible models include the KTM 250, 300, 350, 450, and 500 EXC-F, SX-F, and XC-W series, as well as the Husqvarna FC, FE, and TE models. It is also used in larger displacement bikes like the KTM 950 and 990 Adventure and Super Duke series, and the GasGas EC and MC ranges.

Manufactured to strict DIN6888 standards, this 3x3.7mm key is made from high-strength steel to withstand the significant shear forces generated within the engine's rotating assembly. Its semi-circular design allows it to sit securely in the shaft's keyway, providing a reliable mechanical bond. Replacing a worn or sheared key is essential for maintaining correct engine timing and preventing catastrophic internal damage.

During installation, ensure the keyway on both the shaft and the mating component is clean and free of debris. A small amount of assembly lube can help hold the key in place while sliding the gear or rotor onto the shaft. Always inspect the key for signs of wear or deformation whenever the ignition system or primary drive is disassembled for maintenance.
