My loader has had some extra solenoids added to it in the past. One for a rock breaker and the second for a quick hitch in the hoe. The electrics are not there for any of it and I dont need them either so I want to strip them out (the hoses are in bad shape as well).
Please look at this picture>Link
You>Link can see the new valve block at the bottom in blue, this was for the rockbreaker (three port valve block). Is the hose labelled "existing hose" supposed to be connected into the labeled tee piece.

Second question - New hose 2 and New hose 3 are used for the quick hitch, what is normally installed where they are teed into, just a cap?

Thanks to everyone who can help

Mick

judging from the pic hoses #2 and #3 can be removed and just capped off(at the valve),hose 2 is pressure side and 3 return.Unnumbered new hose appears to be the valve return line which someone replaced with a hose.after that electric valve is removed the 2 large hoses going into it have to be connected together to supply the backhoe valve.
hope this helps.

Thanks agri_con
The un-number new hose runs from there to the other side of the valve shown (cant actually be seen in this photo). Since you mention that hose 3 is a retuen I assume that this hose is also a return line.

I will track the hoses a little better to see if I can understand the circuit and your comments a little better

Thanks

Mick
