I'm finally in the process of putting an 8620 hoe on my 07' 4220. I picked up the 8620 with the subframe attached in TX. It was taken off a tractor in 2010 and has sat ever since...it's brand new.
Directions that I got with the BH are terrible.
The valve body in the picture shows no resemblance to the actual valve body on the tractor. The hydraulics for the BH itself are already there and hooked up. I simply have a pressure and return line from the hoe I have to hook to the tractor.
Question is where on the loader valve body do I hook the pressure line for the hoe up to. There is no labeled Power Beyond Port on the body but there is a "free" plug on the "p" side which I assume is where it needs to go although the directions show it on the same side as the "T" side which I assume is the "tank" return line. Directions say I should use a 90 degree elbow with an 86" long hose which I have but I don't need the 90 bend if I put it where it looks like it should go...?
The return line looks very straight forward. The directions say it goes to the hose right under the right side rockshaft housing. Basically putting a "T" in there and reconnecting the original line with a coupler on the other end of the "T".
Does anyone know of any better directions or am I way over complicating things? These directions also say they are for a B7620BH and a bunch of other tractors, but not mine. They have a 2810, 3510, 3520, 4020 and 4520 with Branson BL20 loader...my loader is a 20S, which should not matter...?
