The purpose of this procedure is to guide the removal of Bifold solenoid valves and the
installation of Peter Paul solenoid valves in their place.
This procedure is to be used in conjunction with the following drawings and documentation.
Hydraulic Power Unit General Assembly Drawing 116700, 116702
Hydraulic Schematic 10612-S
In the following procedure all numbers enclosed in ( ) are balloon numbers from the Schematic
Diagram #10612-S.
1. Close the Customer Power Oil Isolation Valve (58) and the Customer Oil Return
Isolation Valve (21) and Lock-Out per you Local Safety Standards.
2. Use proper container to catch any hydraulic fluid that is lost during this procedure and
dispose of any contaminated fluid properly, according to the code in your local area.
Drain off any residual pressure or hydraulic fluid contained in the Poppet Control Block
(63) and ensure Power Pressure Gauge (71) is reading 0 [zero].
3. Remove any electrical power, from a remote source, going to the solenoid valves.

1. Remove the 3/8 tube lines “A”, “B”, “C”, and “D” as called out in Figure 1 and Figure 2.
2. Disconnect the wiring from the existing solenoid valves. Mark the wires for identification
to ensure correct connections on the new valves.
3. Remove the mounting screws “E” and “F” as called out in Figure 1 and Figure 2 and
remove both solenoid valves.

Note: The tubing may be discarded but, remove and save the tubing nuts for use on
the new tube runs.
Installation of Peter Paul Solenoid Valves
1. Install Tube Fittings in New Valves as shown in Figure 3 below.
2. Mount the new solenoid valves utilizing the brackets, as shown in Figure 3 below.

4. Run a 3/8” tube line from “A” to “B” in Figure 4 and 5. Bend tubing somewhat as shown.
Tube fitting “A” may have to be angularly aligned because of interference with the
bracket.
5. Run a 3/8” tube line from “C” to “D” in Figure 4 and 5. Bend tubing somewhat as
shown. Tube fitting “C” may have to be angularly aligned because of interference with
the bracket.
6. Run ¼” tube line from “E” to “F”, in Figure 4.
7. Run ¼” tube line from “G” to “H”, in Figure 5.
8. Install Conduit Hubs and Solenoid Bushings as shown in Figure 4 and Figure 5.
9. Install new ½” Cable Glands and reconnect the wiring to the new valves paying special
attention to wire markings to insure wires go to appropriate solenoids.
10. This completes the installation. The system must be checked for leakage. If at all
possible, run the following tests and observe the new connections. If it is not possible to
run any tests on the system, inspect regularly during the initial operation. Repair any
leakage found.
11. Open the Power Oil Isolation Valve (58) and the Customer Oil Return Isolation Valve
(21).
12. With the customer installed valves in the actuator header lines closed, use the Manual
Handles of the Poppet Control Valve allowing pressure to hold in the system for a few
minutes in each direction. Repair any leakage found.
13. Once found to be leak free, return the system back on line.
