ENGINE
The vellumoid gasket, Part No. 1408901,
should be sealed with shellac or a sealing compound.
The copper cap screw gaskets should be inspected
to make sure they are of the rolled copper
type, Part No. 394123, instead of the copperasbestos
type used on the first cars. They should
also be inspected to make sure that they are not
mashed out of shape.
When installing the cap screws, the threads
should be dipped in clear Duco and installed
while still wet. The screws should be drawn up
uniformly just tight enough to assure a good seal
of the vellumoid gasket—not tight enough to
mash the copper washers or warp the cover plate.
19. Servicing the Vacuum Pump
Service on the vacuum pump can be obtained
from A C. service stations. However, replacement
of the valves and the diaphragm can be
accomplished simply by taking the pump apart.
Do not under any circumstances separate the two
parts of the housing without holding the pump
head securely because of the strong pressure of
the diaphragm return spring. If care is not taken
in removing the screws which hold the pump
together, the top will fly off and possibly cause
serious personal injury to some one.
