3.4.2. Install ¾” JICF x ¾” JICM 90° fitting to fitting
installed in the “Out” port of the loader valve. Position
this fitting as shown. Install two ¾” JICF x ¾” JICM 90°

3.4.3. Install four 9/16” ORBM x 9/16” JICF straight
fittings to ports A, B, C and D. Install orifice plate in port
“D” with the slotted side facing out or away from valve
body as shown.

Orifice Plate
9/16” ORBM x 9/16” JICF straight fitting
NOTE: Orifice is used to reduce bucket cylinder cavitation during regular dump operation. If your
operation requires a different orifice size, contact factory for blank orifice plate. Blank orifice can be
drilled to your loader application. Smaller hole will reduce cavitation at low RPM but it will decrease dump
speed. Larger hole will increase cavitation at low RPM but it will increase dump speed. Use of regen
during operation will eliminate any cylinder cavitation. See valve operation instructions in this manual for
further loader valve operation instructions.
