WILDEN PUMP & ENGINEERING, LLC

ASSEMBLY:

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 assem-
bled first, then the wetted path. Please find the applicable 
torque specifications 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.

•  Apply a small amount of Loctite

®

 

242 to the shaft stud 

threads.

•  To aid in removal of the liquid chambers, place pump on 

its side.
