When I go to install my 270B backhoe on my 2038R the upper pin holes do not line up. You are supposed to lift up the backhoe all the way with the rockshaft so the cross holes in the mount frame and backhoe align. Mine will not go quite far enough to align the holes. I asked the dealer and he said some backhoes just do that and I should hook up the backhoe hydraulics and use the dipper and stabilizers to push it the rest of the way. It works but it is more difficult and I don't understand why the rockshaft isn't lifting far enough to align the holes. Anyone else have this problem?
