Common questions
How long is the 9420659 extension shaft?
Somfy lists the 9420659 as the Extension Shaft 7mm Hex L=330mm with Screw. That works out to about 13 in of 7mm hex shaft, and the screw that fixes it comes in the package. Somfy rates it to 120 Nm on the LT60 CSI.
Which motors use this shaft?
Somfy lists 32 compatible motors for part 9420659, including Simu DMI5, DMI5Hz, DMI6 and DMI6Hz override motors and Somfy LT50 and LT60 CMO models such as the 550R2 CMO and 6100R2 CMO. Somfy covers the shaft with a 5-year warranty.
What torque can it carry?
Somfy gives a 120 Nm maximum torque for the 9420659 shaft on the LT60 CSI. Stay within that rating when you crank a heavy shutter by hand through the override. Somfy lists rolling shutters as the application and covers the shaft with a 5-year warranty.
Can I angle the crank line?
The 9420659 uses a 7mm hex profile, which matches the Simu universal joint 2005415 with 7mm hex on both ends. Pair the two when the crank has to turn a corner to reach the motor.
