Remove Actuator Valve from Shift Block:
1. Remove the urethane tube (MPM-2052-5.5) from the valve body (VPRO-2003).
2. Unscrew the elbow (TRU-1021) from the end of the actuator (MPM-2598).
3. Remove the nut (MPM-2587) holding the actuator (MPM-2598) in place and pull the
actuator free.
4. Repeat the process for the other end if necessary.
Install Actuator Valve onto Shift Block:
1. Install the actuator (MPM-2598) into the actuator body (VPRO-2001) and install nut
(MPM-2587).
2. Thread the elbow (TRU-1021) into the end the actuator (MPM-2598).
3. Install the urethane tube (MPM-2052-5.5) onto the actuator (MPM-2598).
4. Install the urethane tube (MPM-2052-5) onto the elbow (TRU-1021).

Connect Shift Block Assembly to Pump:
WARNING: Be sure the socket cap screw and trip sleeve (85806-1) is in the center stroke
position or you will damage the equipment.
1. If you need to install the socket cap screw and trip sleeve, do the following:
a. Install the trip sleeve onto the socket cap screw and put removable thread lock
compound on the threads of the socket cap screw.
b. Thread the socket cap screw and trip sleeve into the piston rod until it is tight
against the trip sleeve.
2. Apply a light film of grease (08465) to o-ring and install onto the top of the actuator body.
3. Hold the shift block assembly against the pro pump’s center section. Slightly finger-
tighten the three hex screws (F-HB-04C-20) into the center section.
4. Use one hand to press the shift block assembly upward while tightening the hex screws
in an alternating pattern.
NOTE: This secures the O-Ring (O-S-012) on top of the shift block assembly against the
underside of the cylinder head. If the O-Ring is not positioned properly, the pump will
lose air pressure during operation.
5. Install the air tube between the top of the pump and the shift block.
6. Connect the air hose and the clear tube to the shift block assembly.
