General Information, Straight-Shift
Eaton Fuller 5-speed FS models are fully synchro-
nized. They have five forward speeds and one re-
verse. See
Fig. 10.3 for the shift pattern.
Eaton Fuller 6-speed FS and FSO models are fully
synchronized. They have six forward speeds and one
reverse. See
Fig. 10.4 for the shift pattern.
These transmissions are designed for use with on-
highway, fuel economy engines where a minimum of
shifting is desired and less gear reduction is accept-
able.
Operation, Straight-Shift
1.
Always use first gear when starting to move the
vehicle forward.
NOTICE
Do not rest your foot on the clutch pedal while
driving. This causes partial clutch disengagement
which could cause premature clutch wear.
2.
On synchronized models, press the clutch pedal
to the floor when shifting gears. Double-clutching
is unnecessary.
On unsynchronized models, press the clutch
pedal to the floor to contact the clutch brake only
when engaging the first or reverse gears.
NOTE: If the vehicle is moving when shifting,
depress the pedal just far enough to disengage
the clutch. Pressing it to the floor will engage
the clutch brake, if so equipped, causing prema-
ture clutch brake wear.
3.
To upshift, do the following steps:
3.1
Accelerate to engine governed speed.
3.2
On synchronized models, depress the
clutch pedal and move the shift lever to
second gear.
On unsynchronized models, depress the
clutch pedal and move the shift lever to
neutral. Release the clutch pedal again.
With the shift lever in neutral, depress the
clutch pedal and move the shift lever to
second gear.
3.3
Release the clutch pedal and note the
drop in engine rpm before accelerating up
to engine governed speed again.
3.4
Continue upshifting using the same se-
quence described in the previous step.
Follow the pattern on the shift lever.
4.
To downshift, do the following steps:
4.1
Wait until the engine speed drops to the
rpm noted immediately after the upshift.
