ProForm VR980 EKG (PFEX3311.0) Pedals/Crank Slipping

I have a ProForm VR980 EKG Exercise Bike (Model PFEX3311.0) and it is having a problem where it slips while pedaling. At first I thought it was the belt slipping but I took the bike apart and found that the crank shaft is actually slipping inside the hub. I suspect that it has something to do with the freewheel mechanism but this is where we reach the limits of my knowledge on crank mechanics. Is it possible that something just needs to be lubricated better so the freewheel mechanism "grabs" properly when pedaling or am I going to need to find parts to repair this?

I know how great it feels to get a good workout and an exercise bike can really come in handy. I am sorry for the inconvenience you are having with your bike and I did manage to find the owners manual for your exercise bike in where you can find some good information. I hope this helps while you wait for your expert response.
