DISASSEMBLY
CAUTION: Do not clamp any portion of valve body
or transfer plate in a vise. Any slight distortion of
the aluminum body or transfer plate will result in
sticking valves, excessive leakage, or both. When
removing or installing valves or plugs, slide them in
or out carefully. Do not use force.
NOTE: TAG ALL SPRINGS AS THEY ARE REMOVED
FOR REASSEMBLY IDENTIFICATION.
(1) Remove detent spring-to-valve body screws and
remove spring (Fig. 306).(2) Remove valve body-to-separator plate screws
(Fig. 307) (Fig. 308).
(3) Separate transfer and separator plate from
valve body assembly (Fig. 309). Note check ball loca-
tions (Fig. 310) for proper reassembly.
(4) Remove throttle valve shaft-to-manual valve
shaft e-clip (Fig. 311). Note orientation of washer and
seal (Fig. 312).

CLEANING
Clean the valve body components in a parts clean-
ing solution only. Do not use gasoline, kerosene, or
any type of caustic solution. Dry the parts with com-
pressed air. Make sure all passages are clean and
free from obstructions.
NOTE: Do not use rags or shop towels to wipe off
valve body components. Lint from these materials
will adhere to the valve body components. Lint will
interfere with valve operation and may clog filters
and fluid passages.
Minor distortion of a valve body mating surface
may be corrected by smoothing the surface with cro-
cus cloth. The cloth should be in sheet form and be
positioned on a surface plate, sheet of plate glass, or
equally flat surface. However, if distortion is severeor any surfaces are heavily scored, the valve body
will have to be replaced.
CAUTION: Many of the valve body valves and plugs
are made of coated aluminum. Aluminum compo-
nents can be identified by the dark color of the spe-
cial coating applied to the surface (or by testing
with a magnet). DO NOT polish or sand aluminum
valves or plugs with any type of material, or under
any circumstances. This practice might damage the
special coating and cause the valves and plugs to
stick and bind.
Aluminum valves and plugs should not be sanded
or polished under any circumstances. However, minor
burrs or scratches on steel valves and plugs can be
removed with crocus cloth but do not round off the
valve or plug edges. Squareness of these edges is

vitally important. These edges prevent foreign matter
from lodging between the valves, plugs and bore.
INSPECTION
Inspect the throttle and manual valve levers and
shafts. Do not attempt to straighten a bent shaft or
correct a loose lever. Replace these components if
worn, bent, loose or damaged in any way.
Inspect all of the valve body mating surfaces for
scratches, nicks, burrs, or distortion. Use a straight-
edge to check surface flatness. Minor scratches may
be removed with crocus cloth using only very light
pressure.
Inspect the valves and plugs for scratches, burrs,
nicks, or scores. Also inspect the coating on the alu-
minum valves and plugs. If the coating is damaged
or worn through, the valve (or valve body) should be
replaced.
Inspect all the valve and plug bores in the valve
body. Use a penlight to view the bore interiors.
Replace the valve body if any bores are distorted or
scored. Inspect all of the valve body springs. The
springs must be free of distortion, warpage or broken
coils.
Trial fit each valve and plug in its bore to check
freedom of operation. When clean and dry, the valves
and plugs should drop freely into the bores. Valve
body bores do not change dimensionally with use. If
the valve body functioned correctly when new, it will
continue to operate properly after cleaning and
inspection. It should not be necessary to replace a
valve body assembly unless it is damaged in han-
dling.
