What is the Purpose of the Spring Inside of a Bulldog 12K Square Jack


What is the purpose of the spring in the gear box. Thanks


Helpful Expert Reply:

The spring that comes with gear set # BD500212 for Bulldog 12K jacks is a compression spring. It keeps tension on the upper gear to help keep in place and aligned. I have included a picture that shows where the inner pieces go inside the jack.
