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:

Clean the inside of the center section shaft bore to ensure
no damage is done to new seals.

Stainless bolts should be lubed to reduce the possibility of
seizing during tightening.

Be sure to tighten outer pistons simultaneously on PTFE-
fitted pumps to ensure proper torque values.

Apply two (2) drops of Loctite ® 246 to the shaft internal
threads before the diaphragm assembly.

Concave side of disc spring in diaphragm assembly faces
toward inner piston.
