Replacing the Drop Leg Spring Loaded Pull Pin on a Bulldog 180 Series Square Jack

Question:

The spring broke in one of my landing gears. Is the spring available and how hard would it be to replace?

For a Bulldog 180 series jack you will need replacement drop leg pin # BD500177. It includes the spring, cotter pin, and washer. You should not have to remove the inner drop leg to replace the pin and spring. Start by pulling back on the pin. Then use whatever tool will fit to pull out the cotter key. Then everything should come out.

Then you will put on the spring, washer, and the cotter key goes on last to hold it all in place so put it back in the way that it came out.

The spring alone is not available as a separate part.
