installed). These tank drains should be purged daily with the
drain wrench provided in the loose tools and accessories.

FUEL STRAINERS

To preclude the possibility of contaminated fuel, always cap
any disconnected fuel lines or fittings. The fuel strainer in each
wheel well should be inspected and cleaned with solvent at
regular intervals. The frequency of inspection and cleaning will
depend upon service conditions, fuel handling cleanliness, and
local sand and dust conditions. At each 100-hour inspection,
the strainer plug should be removed from the fuel injection
control valve and the fuel injection control valve screen
washed in fresh cleaning solvent. After the strainer plug has
been reinstalled and safetied, the installation should be
checked for leakage. A leading edge sump strainer, accessible
through an access door on the bottom of the wing, should be
cleaned periodically.

OIL SYSTEM

The engines are equipped with a wet sump, pressure type oil
system. Each engine sump has a capacity of 12 quarts. The oil
system may be serviced through access doors in the engine
cowling. A calibrated dipstick attached to the filler cap indi-
cates the oil level. Due to the canted position of the engines,
the dipsticks are calibrated for either right or left engines and
are not interchangeable.
The oil and oil filter should be changed every 100 hours under
normal operating conditions. The oil drain is accessible
through the cowl flap opening. The engines should be warmed
to operating temperature to assure complete draining of the oil.
The engine manufacture specifies Ashless Dispersant Oils
only. However, for the first 20 hours, MIL-C-6529, Type II Multi
viscosity 20W-50 Corrosion-Preventive Oil is used. It is recom-
mended that this oil be removed and the oil filter changed at 20
hours of engine operation (not to exceed 25 hours). If oil con-
