advisable to remove rocker arms and shaft. If
only one or two tappets are to be removed, pro-
ceed as follows:
Install valve spring compression Tool, C-
3024,
over rocker arm (Fig. 22) so heel of tool
rests on valve stem side. Make certain valve
is seated and tappet body is resting on low
point of camshaft lobe. Refer to Paragraph 17
"Locating the Low Point of Camshaft Lobe In
Conjunction With Valve Tappet Face." Using
handle of tool for leverage, compress valve
springs sufficiently to raise rocker arm above
push rod. While holding rocker arm in this
position, slide rocker arm to one side along
the tube.
IMPORTANT
To avoid damage to valves, be sure that piston
head is well below top of travel before com-
pressing valve springs.
Drain cooling system below level of intake
manifold. Remove carburetor air cleaner. Dis-
connect coil wires and wire from heat indicator
sending unit. Disconnect heater hose and car-
buretor heat tube at the integral choke. Re-
move intake manifold, carburetor and coil as
an assembly. Remove tappet chamber cover
and gasket.
Insert hooked portion of Tool C-3216 into
hole in tappet body (Fig. 23). (This portion of
tool can be used to remove tappets without a
varnish build-up). Lift tappet out of bore. If
tappet sticks, slide puller portion of Tool C-
3216 through cylinder head (push rod) holes
(Fig. 24) and seat firmly in cap of tappet. In-
sert puller pin through tappet body and tool
shaft in holes provided. Grasp tool handle and
pull tappet out of bore with a twisting motion.

If all tappets are to be removed, remove hy-
draulic tappets and place them in their respec-
tive holes in Tappet and Push Rod Holder,
Tool C-3068. This will insure installation of
tappets in their original locations.
NOTE
Do not disassemble a tappet in dirty surround-
ings or on a dirty work bench. The plunger and
tappet bodies are not interchangeable. The
plunger and valve must always be fitted to the
original body. It is advisable to work on one
tappet at a time to avoid mixing parts. Mixed
parts are not usable.
