Problem with motorized trailer dolly

Hey everyone, i pick up a motorized trailer dolly to help move my trailer around in tight spots. however there is a problem with it. Hoping someone has one and can offer a little help. The problem is the crank on the motor shaft just spins, not sure how it secures to the shaft. Does any one know? thanks for any help.






  • The drive motor is a repurposed 12DC winch. The knob on the left in your pic should be the freespool mechanism. It should pull out and half turn to engage...

    Look over the motor and see if you can find a nameplate. Get online documentation from there....

    The drive sprocket is seated where the winch cable would be wound.
  • No brand name or model number you can google? That would be where I start.
  • wonder if the black knob on side is the engagement mechanism.. twist, push or pull...
  • yea that what i was thinking, Just hoping some one has one, This way ill know for sure what to fix..

    I would think it is either a shear pin that possibly broken or a key on the shaft. Should be very easy to take apart and see whats broken or missing. If you have to I bet a shop that works on lawnmowers or maybe outboard motors could figure it out.
