Okay David, here is what I believe to be true either totally or at least in part. Your steps are probably powered by a AM Equipment motor. It could be a window step motor from earlier than the AM Equipment motors but without a photo or description from your manual I cannot say for sure.
If your steps have been maintained but are sluggish it may just be the motor.
If you will post a picture of the motor and send me a PM telling me that it has been posted I'll identify it and tell you how to proceed.
I difficult part of this is deciding who designed it and what motor it is using.
I'll bet you that it is the motor.
David
