ASSEMBLING SERIES "A K"
Body, Rocker Arm and Link Assembly
1. Assemble link, rocker arm and rocker arm spring in body.
Insert rocker arm pin through hole in body, engaging link and
rocker arm. Use a punch and stake die cast metal of body over
end of pin in one place at each end, to retain pin in place.
Note: It has been found that the assembly of the rocker arm
pin can be simplified by first assembling a piece of .240" drill
rod through- the rocker arm pin hole in one side of the body far
enough to engage the rocker arm and link, then insert rocker
arm pin from the opposite side, pushing out the drill rod until
the pin is in proper position. If after assembling the rocker arm
pin it is found that the rocker arm or link does not work freely,
this can be corrected by placing a punch against the opposite
end of the rocker arm pin, tapping it lightly with a small
hammer in the reverse direction from which it was assembled.
Diaphragm and Pull Rod Assembly
The Diaphragm for Series "AK" pump is an assembly
including protector washers and pull rod and will be serviced
as a unit.
To correctly assemble diaphragm in pump body, proceed as
follows:
1. Place diaphragm spring, in position in pump body.
2. Place diaphragm assembly over spring, centering upper
end of spring in lower protector washer.
3. Press downward on diaphragm, and at the same time
assemble slot in diaphragm pull rod over the end of the link.
Valve and Cover Assembly
1. Blow out valve chamber and make certain that no foreign
particles are present which might prevent valve from seating
properly. Also observe that no burrs or irregularities exist in the
valve seat and that the valve seat is securely held in place in the
upper cover.
2. Place a drop of Finol on the fibre valve, and put in proper
position in valve chamber. Be certain that valve lies flat against
the valve seat and is not standing on edge or tipped.
3. Insert valve spring on top of valve.
4. Place fibre gasket on valve plug and then place stem of
valve plug into the coil spring and tighten plug securely. Be
certain that the stem of the valve plug does not distort the valve
spring but fits properly inside of it.
Cover Assembly
1. Push upward on rocker arm until diaphragm is level with
the body flange.
2. Place cover assembly in proper position designated by
mark on flanges made before disassembling the pump.
3. Install cover screws and lockwashers, tightening only
until they barely engage lockwashers.
4. Release rocker arm, which will place the diaphragm in
its highest position then
5. Tighten cover screws alternately and securely.
PROCEDURE IN ASSEMBLING SERIES "AB" Body,
Rocker Arm and Links Assembly
1. Assemble rocker arm, fuel link, link spacer and vacuum
links on rocker arm pin bushing in same relative position as
when removed from the pump.
2. Place the hooked end of one of the Vacuum links on top
of the other vacuum link (this is necessary to permit assem-
bly in body).
3. Place assembly of links, rocker arm, link spacer and
rocker arm pin bushing in body, making sure that rocker arm
spring seats properly on ear of link spacer.
4. Assemble rocker arm pin in position. Place washer over
end of pin, then swedge counterbored end of pin over se-
curely against washer.
Assembling Fuel Diaphragm in Pump
Invert body, rocker arm and links assembly allowing link
to fall against body stop. (Hooked end of one. vacuum link
should be on top of the other vacuum link during assembly.)
Insert a small tool or screw driver to hold link in this posi-
tion. Place diaphragm spring in position in lower diaphragm
protector washer, then insert pull rod and diaphragm assem-
bly in position in body. By depressing the diaphragm spring,
hook the pull rod over the hooked end of the link. Make sure
that the diaphragm spring is seated properly in body and in
the lower diaphragm protector washer.
Valve and Cover Assembly
1. Blow out valve chamber and make certain that no
foreign particles are present which might prevent valve from
seating properly. Also observe that no burrs or irregularities
exist in the valve seat and that the valve seat is securely held
in place in the upper cover.
2. Place a drop of Finol on the fibre valve, and put in proper
position in valve chamber. Be certain that valve lies flat
