A.
When starting the engine, torque is transmitted from the starter
(13)
through the adapter
components
(14
thru
22)
depending on the adapter configuration. As worm wheel
(16)
is
turned, the spring mounted on its hub is tightened to grip the knurled drum of the shaft gear
(17).
After the engine is started, the spring returns to its normal position, thus disengaging
the starter. Some starter adapters incorporate an additional housing which provides for two
additional accessory drive pads. Gears
(19, 20)
provide the torque for these drives. In
addition, all
TS10-350 engines incorporate a scavenge pump in the starter adapter gear. The
scavenge pump gears
(213)
are driven by the starter shaftgear
(17).
The scavenge pump gear
(21)
is keyed to the starter shaft gear
(17).
B.
Torque from the crankshaft gear
(1)
is transmitted directly to the camshaft gear
(3).
C.
The camshaft gear (3) drives the magneto gears
(11, 12).
The alternator drive gear
(23)
meshes with the inner camshaft gear and turns the alternator shaft through
a
rubber bushing
drive coupling. The splined end of the oil pump drive gear
(9)
mates with the internal spline
of the camshaft gear and transmits torque to the oil pump driven gear
(10).
D.
The governor drive bevel gear
(6)
is keyed to the camshaft
(4)
and meshes with and
drives the governor bevel gear
(7).
E.
The splined end of the fuel pump drive shaft
(8)
mates with the internal spline of the
governor gear.
