Install Foot Valve Assembly:
1. Insert the cylinder (15991-1) and foot valve body onto the piston rod.
2. Coat the threads of the two hex screws with a thin layer of grease. Then gently hand-
tighten the screws to secure the foot valve collar, foot valve body and cylinder to the
pump’s center section (85728-3). Do not completely tighten the assembly yet.
3. Check the orientation of the inlet elbow and reinstall as noted earlier.
4. When the foot valve body is oriented correctly, tighten the hex screws to 13 ft.-lb (18 N-
M, 1.6 KP-M).
NOTE: Tighten the hex screws in an alternating pattern to ensure a good seal.
WARNING: Do not over tighten the hex screws on the foot valve collar. Damage to the
center section will occur.
Install Shift Block Assembly:
1. Place the new O-Ring (O-S-012) on top of the shift block assembly and lubricate it with
grease (08465).
WARNING: Before attempting to connect the shift valve assembly to the pump, be sure
the socket cap screw is in the center stroke position. If the screw is not in the center
stroke position, you will damage the equipment.
2. Coat the three hex screws with a thin film of grease. Then hold the shift block assembly
against the pump’s center section and slightly finger-tighten each screw.
3. 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.
Install the air tube between the shift block and the top of the Pro pump.
Install Pro Pump:
1. Remove the pump from the vise and install on the unit with hex cap screws.
2. Connect all hoses to the pump.
