OPERATION 219
Note:
When making a SPLIT SHIFT from gear to gear, the splitter switch must not
be actuated, either up or down, until the main box is in NEUTRAL. When making
a SPLIT SHIFT in the same gear to a preselected gear, especially under a heavy
load, the splitter will not shift until the driveline torque is relieved. This can be done
by depressing the clutch pedal and releasing it, or by backing off the throttle and
reapplying it. The splitter switch must not be actuated, either up or down, until
IMMEDIATELY before the driveline torque is relieved. When making a RANGE
SHIFT, it is important to preselect the range shift. This means that the range selector
must be moved to its next position (up or down) BEFORE the gearshift lever is
moved. Then move the gearshift lever through NEUTRAL to the next desired gear
position. As the lever passes through NEUTRAL, the range shift will be completed.
Upshift —
For purposes of explaining the shifting procedures through ALL
gears, assume that the vehicle has a full load and will climb a slight grade.
Before moving the vehicle, the range selector must be in LO range and the
splitter switch in LO-split. With the shift lever in NEUTRAL, move the splitter to
LO-split (if needed), then the range to LO range (if needed).
Refer to the shift pattern and move the shift lever to LO speed gear (LO
range, LO-split). Apply accelerator, engage the clutch, and accelerate to
governed speed. Shift up through first, second, third-fourth speed gears,
double-clutching between the gears.
To continue while in fourth gear (LO-split), flip the range selector up to HI range
(preselect), then move the shift lever through NEUTRAL to fifth gear. As the
lever moves through NEUTRAL, the range shift to HI will be completed. You
are now in fifth gear LO-split (HI range). Use a combination of the splitter and
shift lever to continue shifting to fifth HI-split, sixth LO-split, sixth HI-split and so
on, until you reach eighth HI-split. Remember to double-clutch between gears.
To upshift from LO-split to HI-split (in the same gear), accelerate the engine
to governed speed, move the splitter switch to HI (preselect), depress the
clutch and back off the accelerator pedal. Reapply the accelerator and engage
the clutch when the audible shift is heard, or when the engine speed falls by
approximately 200 rpm. Depressing the clutch may not be necessary to break
the driveline torque, but this will vary with road and load conditions.
To upshift from a HI-split gear to the next higher gear’s LO-split (in HI range),
accelerate the engine to governed speed, then move the splitter switch to LO
as you move the shift lever through NEUTRAL to the next higher gear. Note
that the splitter switch must not be actuated down to the LO position until
the main box is in NEUTRAL.
Downshift —
Shift from eighth HI-split to eighth LO-split, then seventh
HI-split, seventh LO-split and so on (double-clutching between the gears),
until you reach fifth LO-split.
