starting motor efficiency due to poor or corroded connections
or improperly soldered terminals. In making this check, partic-
ular attention should be given the ground connection to the
frame. (See Engine Tune-up, Section 3.)
All starting motor commutator end bearings are provided
with an oil hole accessible by swinging the oil hole cover to one
side. This oil hole is located on the end of the bearing housing.
Some of the starting motors are also provided with a hinged top
oiler located in the frame near the drive end for lubrication of
the drive end bearing. Add a few drops of light engine oil in
each oiler or oil hole. (B and Dac, Figure 612).
Complete Inspection
The complete inspection should include the removal of the
starting motor, complete dismantling, truing up of the commu-
tator, installing of new brushes if needed, a check of the bear-
ings with replacement of those that are worn and an inspection
of the Bendix drive for worn parts or a distorted spring. The
starting switch and starting circuit should also be checked as
outlined in the tune-up inspection.
To replace the starting motor grounded brushes it will be
necessary to cut the rivets holding the brush holders and brush
ground strip to the commutator end plate assembly. When
re-riveting be sure the rivets fit the holes snug and that they are
riveted tight so as not only to hold the brush holder firmly in
place but to secure a positive ground connection for the brushes.
To replace the insulated brushes, unsolder the brush pigtail
from the field coil and remove the old brushes. When inserting
the pigtail of the new brushes it will probably be necessary to
open up the loop slightly in the field coil. Be sure the pigtail is
inserted the full depth of the loop after which it should be
clinched to hold the pigtail securely before re- soldering. A
good soldering job must be done to assure full efficiency of the
starting motor.
BENDIX STARTER DRIVE
Failure of the Bendix drive to engage the flywheel gear in cold
weather indicates the presence of gummy dirt on the screw threads
of the Bendix Drive, which must be cleaned off in the following
manner:
Press the starter button and release quickly. Repeat until the
Bendix pinion is fully meshed with the flywheel gear. With a paint
brush dipped in kerosene, brush the screw threads back of the
pinion, rotating same slightly. Very little kerosene should be used.
Never use gasoline because it removes all lubrication.
Start the engine several times in order to work the kerosene into
the gum on the screw threads of the Bendix Drive. It is desirable to
remove excessive kerosene, after cleaning, by brushing with a dry
brush or wiping with a clean cloth.
While the Bendix Drive can be cleaned without removing the
starter, it is recommended that the starter be removed before cold
weather each year and the screw threads cleaned according to the
above instructions.
Never wash the whole Bendix Drive in kerosene or gasoline.
Clean only the screw threads. In case the lubrication is cleaned off
of the armature shaft under the pinion, it should be relubricated.
The Eclipse Machine Company, of Elmira, New York, who
manufacture the device, recommend Gredag No. 314 for relubrica-
tion. If this lubricant is not available use a few drops of S.A.E. 10
Engine Oil. Do not apply lubricant to the screw threads.
HELPFUL POINTERS
For those that are not entirely familiar with electrical work and
the approved methods for handling certain operations the follow-
ing suggestions may be of help.
Brushes
Whenever new generator brushes are installed they must be
carefully fitted to the commutator by sanding to assure of at least
