VACUMOTIVE DRIVE
(Optional Equipment)
Vacumotive Drive, which is available as a factory installed option, or may be
installed by your Authorized Hudson Dealer, provides a means of engaging and
disengaging the clutch automatically without using the left foot. It utilizes the engine
vacuum and is operated by momentarily lifting the foot from the accelerator pedal
to disengage the clutch and depressing the accelerator pedal to engage the clutch.
A switch, with two buttons marked "VAC" and "OFF," mounted on the instrument
panel permits the driver to change from conventional clutch operation to automatic
operation by merely pressing in and releasing the "VAC" button. To revert to
conventional drive press the "OFF" button. This can be done at any time.
A centrifugal governor switch prevents free wheeling or coasting in high gear at
speeds above 19 miles per hour. Under certain conditions, such as when driving on
icy or slippery pavements, or when descending steep grades when free wheeling
may not be desired the driver may revert to conventional by pressing the "OFF"
button. Clutch operation will then be by conventional means.
OPERATION—Press in the "VAC" button. Depress the clutch pedal manually as
Vacumotive Drive is operative only when the engine is running. Place the Handy
Shift lever in neutral position and start the engine. Move the lever to the desired gear
position and depress the accelerator pedal.
Note: If moving in reverse gear press the
accelerator pedal lightly.
When moving in low gear accelerate to the desired speed for shift into second gear.
Lift the foot from the accelerator pedal, move the gear shift lever into second gear
position and then depress the accelerator pedal. Repeat this operation for the shift
into high gear.
LUBRICATION
—
Vacumotive
Drive linkage connections should be lu-
bricated every 1,000 miles with a few
drops of light engine oil. Also apply a
few drops in the mounting bracket pivot
hole (Y), Fig. 36.
At intervals of 10,000 miles the vac-
uum power cylinder should be lubricated
by removing pipe plug (Z) and injecting
one ounce ofHUDSON SHOCK AB-
SORBER FLUID. The piston rod end to
bell-crank bolt and the valve rod to lever link should be removed and the piston rod
rotated with an in-and-out movement to thoroughly distribute the oil over the piston
and oil wick.
