POWER FLOW (con’t.)
1. Power (torque) from the engine flywheel is transferred to the input shaft.
7. Torque is split between the two auxiliary countershaft drive gears. (In direct drive or high range,
power is delivered to the output shaft from the
auxiliary drive gear through a self-aligning sliding
clutch gear.)
2. Splines on input shaft engage internal splines in
hub of drive gear.
3. Torque is split between the two countershaft drive
gears.
8. Torque is delivered by the two countershaft low
range gears to the low range gear.
4. Torque delivered by two countershaft gears to
mainshaft gear which is engaged. Diagram shows
first speed gear engaged.
9. Torque delivered to output shaft through selfaligning sliding clutch gear.
10. Output shaft is attached to drive line.
5. Internal splines in hub of mainshaft gear transfers torque to mainshaft through sliding clutch
gear.
6. Mainshaft transfers torque to auxiliary drive gear
through a self-aligning coupling gear located in
hub of auxiliary drive gear.
