Reassemble the pump making sure the vanes are inserted properly. (See
Figure 5-2: “Primer Pump Parts Overview” on page 37.)

Use a Lithium-based grease with 1% to 3% Molybdenum Disulfate and
lubricate the rotor cylinder shaft at the bearings.

IMPORTANT !

DO NOT USE A LUBRICANT ON THE ROTOR VANES AND CYLINDER SLOTS.
LUBRICANT AND COLD WATER FORM AN EVENTUAL GUMMY RESIDUE THAT
RENDERS THE PRIMING SYSTEM INOPERATIVE. A COMPLETE AND THOR-
OUGH DISASSEMBLY AND CLEANING IS THEN REQUIRED.

SPV VALVE REPAIR

The Hale SPV is designed to provide trouble free service with a minimum of
preventive maintenance. Performance degradation can result from a ruptured
diaphragm or worn seat on the valve. A Hale SPV repair kit that contains a
manual, seal ring, valve and diaphragm is available from Hale Products, Inc.
Order Hale repair kit, p/n: 546-1680-00-0. Also see Figure 5-3: “Hale SPV
Parts Overview” on page 40.

1.

Disconnect the vacuum hose from the hose connection on the valve body.
Have clean disposable shop rags and oil dry handy.

2.

Remove the 7/16”-14 nuts that hold the valve assembly to the pump body or
universal adapter. Remove the valve assembly, strainer and seal ring from
the pump.

3.

Match mark, tag and/or note, or photograph the orientation of all mechani-
cal and electrical components and connections before disassembly. This
aids in proper reassembly.

4.

Match mark the diaphragm cover and valve body for proper realignment of
the drain hole during re-assembly.

WARNING !

PARTS UNDER SPRING TENSION CAN BECOME PROJECTILES AND CAUSE
SERIOUS INJURY. WHEN REMOVING OR INSTALLING THESE PARTS MAKE
SURE THEY ARE RESTRAINED AND SPRING TENSION IS RELEASED SLOWLY.
