Reassembly Hints & Tips
Step 2
Optional: Install a single-point exhaust gasket (04-2639-52). The single-point air valve
gasket can be purchased as a spare part or included with the purchase of a new Pro-
Flo SHIFT pump.
Upon performing applicable maintenance to the air
distribution system, the pump can now be reassembled.
Please refer to the disassembly instructions beginning on
page 14 for photos and parts placement.
To reassemble the pump, follow the disassembly
instructions in reverse order. The air distribution system
needs to be assembled first (beginning on page 17), then
the diaphragms and finally the wetted path. The applicable
torque specifications are on this page.
The following tips will assist in the assembly process:
• Lubricate the air valve bore, center section shaft and pilot
spool bore with NLGI grade 2 white EP bearing grease or
equivalent.
• Clean the inside of the center section shaft bore to ensure
no damage is done to new shaft seals.
• A small amount of NLGI grade 2 white EP bearing grease
can be applied to the muffler and air valve gaskets to
lubricate gaskets during assembly.
• Make sure that the exhaust port on the muffler plate is centered between
the two exhaust ports on the center section.
• Stainless bolts should be lubed to reduce the possibility of
seizing during tightening.
