Mounting Bolt Dimensions of the Hydraulic Jack w/ Integrated Counter Balance Valve e23VV

Question

Question:

Hello. I have some questions regarding your hydraulic trailer jack e23VV, Im working on repairing a damaged jack on a Gator gooseneck. It needs at least a new cylinder as well as other parts. This 323VV looks like it could be a direct bolt on replacement. Can you provide the bolt pattern dimensions, the diameter of the cylinder, and the hose/fitting style/size for the hydraulic hookup? Thank you.

Hey Harry! I linked a dimensional diagram below of the bolt pattern dimensions you requested for the Hydraulic Jack w/ Integrated Counter Balance Valve item # e23VV. The cylinder is 5" in diameter.

There are two hydraulic fittings:

9/16-18 #6 SAE JIC 37 degree flare fitting retract port

9/16-18 #6 SAE JIC 37 degree flare fitting extend port
