I have a bull dog 4000# camper jack. I need a replacement gear that is driven by the electric motor. I can not find one. Do you have a part for that.

I spoke with my contact at Bulldog and he said they do not offer replacement parts to rebuild the gear box for the Bulldog Powered-Drive Trailer Jack, # BD500200. Typically the gears get damaged due to over extension or retraction. Before installing a new jack, power it up and extend it all the way with no load, back it up a bit and mark the leg. Do the same for the retraction. This way you will have visual marks of when to stop extension or retraction.
