Section 21 - Transmission, Drivelines - Chapter 1
POWER FLOW (FORWARD CREEPER DRIVE SPEEDS)
FIFTH CREEP GEAR - As the operator selects fifth creep speed, he simultaneously disengages the first-speed
clutch and engages the third-speed clutch. Power then flows from the speed transmission input shaft, through the
creep-speed clutch on the countershaft, to the third-speed clutch on the output shaft, across to the master clutch.
Power flow through the range transmission is the same for speeds fourth creep through sixth creep.
SIXTH CREEP GEAR - As the operator selects sixth creep speed, he simultaneously disengages the third-speed
clutch and engages the fifth-speed clutch. Power then flows from the speed transmission input shaft, through the
creep-speed clutch on the countershaft, to the fifth-speed clutch on the output shaft, across to the master clutch.
Power flow through the range transmission is the same for speeds fourth creep through sixth creep.
NOTE: High range clutch pack is not used for the creeper speeds.
