Connect Shift Block Assembly to Pump:
WARNING: Be sure the socket cap screw (00260) 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, refer to drawing (VPRO-
45110) Pro Pump Assembly and do the following:
a. Install the trip sleeve onto the socket cap screw (F-CS-04C-24-SS) and put
medium-strength Loctite ™ on the threads of the socket cap screw (F-CS-
04C-24-SS).
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 Lubriplate ® to o-ring (O-S-012) 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.
Test Operator Valve:
1. Test the valve to ensure that there is proper air flow intake and output.
2. Increase the pump pressure.
3. Open the gun over an appropriate container.
4. If the pump operates, the shift block works.
