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 assembled first,
then the diaphragms and finally the wetted path. The
following tips will assist in the assembly process.
• Lubricate 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-steel bolts should be lubed to reduce the

possibility of seizing during tightening.

• Use a mallet to tap lightly on the large clamp bands

to seat the diaphragm before tightening.

SHAFT SEAL INSTALLATION:

PRE-INSTALLATION
• Once all of the old seals have been removed, the

inside of the bushing should be cleaned to ensure
no debris is left that may cause premature damage
to the new seals.

INSTALLATION
The following tools can be used to aid in the installation
of the new seals:
  Needle-Nose Pliers
  Phillips Screwdriver
  Electrical Tape
•   Wrap electrical tape around each leg of the needle-nose

pliers (heat shrink tubing may also be used). This is done
to prevent damaging the inside surface of the new seal.

• With a new seal in hand, place the two legs of the

needle-nose pliers inside the seal ring. (See Figure A.)

• Open the pliers as wide as the seal diameter will allow,

then with two fingers pull down on the top portion of
the seal to form a kidney shape. (See Figure B.)

• Lightly clamp the pliers together to hold the seal in the

kidney shape. Be sure to pull the seal into as tight of
a kidney shape as possible, this will allow the seal to
travel down the bushing bore easier.

• With the seal clamped in the pliers, insert the seal into

the bushing bore and position the bottom of the seal
into the correct groove. Once the bottom of the seal is
seated in the groove, release the clamp pressure on the
pliers. This will allow the seal to partially snap back to its
original shape.

• After the pliers are removed, you will notice a slight

bump in the seal shape. Before the seal can be properly
resized, the bump in the seal should be removed as
much as possible. This can be done with either the
Phillips screwdriver or your finger. With either the side
of the screwdriver or your finger, apply light pressure
to the peak of the bump. This pressure will cause the
bump to be almost completely eliminated.

• Lubricate the edge of the shaft with NLGI grade 2

white EP bearing grease.

• Slowly insert the center shaft with a rotating motion.

This will complete the resizing of the seal.

• Perform these steps for the remaining seals.
