20. OPTIONAL ORIFICE KIT
FOR USE WITH HYDRAULIC KITS UTILIZING KMW SUPPLIED VALVE
20.1.1. Optional Orifice Installation: Purchase orifice plate through loader service parts. Remove female quick
coupler from port “B2”.Install orifice fitting by dropping it into port "B2" with slot of orifice facing upward.
Reassemble female quick coupler into Port "B2" to secure orifice into port.
Port "B2" in Loader Valve. Orifice (slot outward). Female Quick Coupler.
Port "B2" in Loader Valve.
NOTE: Optional orifice is used to reduce bucket cylinder cavitation during regular dump operation. If your
operation requires a different orifice size, order blank orifice through service parts (See parts pages for
part number). 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 dumping operation will eliminate any bucket cylinder cavitation
and eliminate orifice use. See valve operation instructions in this manual for further loader valve operation
instructions.
