OPERATION 189
1. With the vehicle standing still, apply the clutch brake by pushing the clutch
pedal all the way to the floor: the clutch brake is applied when the clutch pedal
is fully depressed (approximately the last 13 mm (1/2 inch) to 25 mm (1 inch)
of pedal travel past normal, of clutch brake pedal travel, varies between the
air assist and non assist release systems. The variance includes general
tolerances and amount of pedal free-play. Typically about the last 13 mm
(1/2" inch) on the air assist and about the last 25 mm (1 inch) on the non
assist control systems).
Note:
When the clutch is disengaged, a slight but definite resistance to clutch pedal
downward travel will be felt in approximately the last 13 mm (1/2 inch) to 25 mm
(1 inch).
CAUTION
Vehicles equipped with the air assist clutch control system use less pedal travel.
The clutch brake engages sooner in the pedal stroke than conventional non assist
systems. To avoid system damage, be careful not to engage the clutch brake during
normal shifting.
2. Shift the transmission into first or reverse gear, engage the clutch and
accelerate. The clutch brake is only to be used when the vehicle is stopped
and is shifted into first or reverse gears. It is not designed to be used as an
upshifting aid.
CAUTION
Clutch brake damage may result if used while the vehicle is in motion. The clutch
brake must NOT be used when making a downshift or an upshift.
Double-Clutching
Double-clutching is a way to bring the speed of the transmission gears into
synchronization so that the shift can be made without a clash. The engine is
used to speed up the counter shaft for a downshift and to slow it down for an
upshift.
Note:
For all non-synchronized transmissions, double-clutching is necessary on
downshifts and upshifts. It is advisable to use the torque-limiting clutch brake to
engage first and REVERSE gears and to double-clutch for gear ratio changes.
