MAINTENANCE.
The
starting circuit
should
be inspected
at regular
intervals,
the frequency of
which should be
determined by
the amount of service
and the conditions
under which the aircraft
is operated. It is recommended that
such inspection be made
at each 100 hours and include
the following:
a. The battery should
be checked with a hydrometer
to be sure if is fully
charged and filled to the proper level with approved water. A load test should
be made to determine battery condition. If dirt and corrosion have accumulated
on the battery, it should be cleaned with a solution of baking soda and water. Be
sure none
of the solution enters
the battery cells.
b. The starting circuit wiring should be inspected to be sure that all connec-
tions
are clean and tight and that the
insulation is sound. A voltage
loss test
should be made to locate any high-resistanceconnections that would affect start-
ing motor efficiency. This test is made with a low-reading voltmeter while crank-
ing the engine or
at approximately 100 amperes, and
the following limits should
be used:
1. Voltage loss from insulated
battery post to starting motor
terminal -
0.3-volt
maximum.
2. Voltage loss from battery ground post to starter frame - 0.1-volt
maximum.
NOTE
If
voltage loss is greater
than the above limits,
add-
itional tests should be made over each part of the cir-
cuit to locate the high-resistance connections.
c. No lubrication
is required on the starting motor
except at the time of over-
haul. Then lubricate the entire shaft under Bendix Drive, fill grooves in arma-
ture shaft at drive end and pack gear box with 1.3 to 2.0 ounces of Lithium Soap
Base
Grease #1925 Molytex
"O" or equivalent.
d. The starting motor should
be operated for a few seconds with
the ignition
switch off, or in airplanes with a combination starter and ignition switch, by dis-
connecting
the magneto "P" leads. This
is to determine that the pinion
engages
properly and that it turns freely
without binding or excessive noise.
After check-
ing the system,
reconnect the "P" leads. Then
the engine should be started
two
or three times to see that the pinion disengages properly when the engine is shut
down.
11-62. OVERHAUL. If during the above inspection any indication of starting
motor difficulty is noted, the starting motor should be removed from the engine
for cleaning and repair.
