To plumb an A M E Tilting Hitch.

These are the plumbing options
1. Spool Valve
2. Half Breaker Valve
3. Diverter Valve.

1. Using a spool from the main bank is the most preferred way to plumb the TILTING HITCH.
You will need to use the pilot pressure to operate the spool valve.
Source the oil from under the cab from the tank side of the isolating lever. You will require VALVE No 4WEG  J  6XLE 24V N9KE MOTOR Spool to operate the spool.
This requires electric hand control with LEFT and RIGHT buttons.

2. When the excavator has hammer plumbing it uses half the spool with the hammer piped backed to tank Use VALVE No 4 W E G C 6 X S G 24 VOLT to pick up oil from pilot pressure from the tank side of the isolating lever to operate HALF the spool. Pipe the oil from the spool valve to VALVE 4 W E 6 E 6 E C 24V to allow you to operate the TILT left and right. You will require 2 electric diodes between the pilot valve and the directional valve to block electric feed back.
This requires an electric hand control with left and right Buttons.

3. When there are no spools available, use a 6 port diverter valve
No SVB 04 9L 24V,  THIS valve is good for 90 litres per min, and is a good option to be placed in line to OFFSET BOOM, AUGER or BUCKET cylinder with a button in the lever.
OIL tube lines are to be no less the ½ inch, on Boom and Dipper arm.

X LINE RELIEF VALVES are NOT REQUIRED as TILT is designed to operate at machine pressure. Low oil flows and pressures reduce the SPEED and efficiency of this ATTACHMENT.
This attachment is an extension of the operators HANDS so give him a GO.
