Replacement Nut and Screw for a Bulldog 10K or 12K Capacity Landing Gear Trailer Jack


I have a Bulldog 4inch square leg side wind landing gear style jack. I believe its 10,000/12,000# rated. The nut at the top of the jack that the screw runs in is worn out. Its 4inch square and slides into the outer tube secured by 2, 1/2inch pins. It appears to be gray cast iron. Can this nut be purchased?

Expert Reply:

The nut by itself is not available as a separate part but we do have the screw and nut assembly, # BD500250. It is designed just like you have said with the 2 roll pins and is rated for 10K lift and 12K static load.

We also have # BD500217. It is designed to fit Bulldog series 182 jacks from 2003 to present, with 12K capacity.
