all spark plugs, or seal the holes with suitable threaded metal
plugs and gaskets. For valve-in head engines, valve covers
should be removed, and the preservative oil sprayed over rocker
mechanisms, interiors of valve covers, between cylinder blocks
and side plates, over push rods, and into oil filler and
crankcase ventilator pipes. The entire fuel system, including
carburetor, fuel pump, strainer, and fuel lines, should be
drained; and all parts should be dry. The lubricating oil
system should be drained, and a yellow tag attached to the oil
filler cap with the following information:

a)
Centrifugal Pumps. The pump shaft should be covered with heavy
grease. All openings should be capped or covered securely, and
all petcocks left open.
b) Rotary Pumps. The procedure should be as indicated for
centrifugal pumps. One additional requirement is that a small
amount of heavy oil should be poured into the rotor inlet and
the pump rotated by hand until the rotor and moving parts are
thoroughly covered with oil.
Steam-Driven Pumps. Steam lines and water-packing lines should

be drained, and all openings capped or blanked off. Packing
nuts should be loosened. A small amount of oil should be
poured into the steam chest, and the valves should be moved to
ensure a coating of oil between the valves and seats and on the
cylinders, rings, and pistons. Petcocks should be left open,
but all other openings should be covered to exclude dust and
foreign material. The cylinder head should be loosened on the
water end to ensure that all water is eliminated. Cylinder
walls and pistons of water pumps `should be covered with a
protective film of oil.
