SINGLE-POINT EXHAUST
Step 1
Step 2
Remove the pilot exhaust muffler in the pilot
bleed port located at the front of the center
block. Install 1/4" NPT pipe plug (00-7010-
08) into the bleed port.
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.
REASSEMBLY HINTS AND TIPS
Upon performing applicable maintenance to the air distribution system,
the pump can now be reassembled. Please refer to the disassembly
instructions 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,
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.
