Furler motor to gearbox sm2000

michael winand

Hi.I have encountered this problem with my main furler motor. 
I have sheared the shaft on the leroy somer motor where it enters the gearbox. 
Any suggestions on how I would be causing this problem?
The gearbox is still working well. As I have it apart I will give it a full service. 
I would like to ask if anyone has been through this issue and what action is needed to fix this. 
I'm not sure if this is a design that allows the shaft to be replaced as a sacrificial item to prevent overloading?I have taken a photo of the issue. 
Apon removal it was still the original installation. The electrical brushes still have most of their length intact. 
Many thanks to the group
