Ford 5640 lift arms

[allinshaver]

The lift arms will not go up .I bought this tractor used they never have worked they tapped in to the hydraulics to add a front end loader I took the loader off and just used use the tractor. Does any body have an answer to why the lift arms will not work.

Welcome to TBN!

When you say they tapped into the hydraulics, is it now returned to original?
Doesn't go up we can assume?
Most likely need to take the 3pt top cover off and see what the lift puston/cylinder looks like and see if you have flow to it.

Maybe a slightly simpler first step would be to post some photos of how/where this "tapped into the hydraulics" stuff took place.
