suction pressure will be above the control point; the valve will
m aintain
a
bleed
from
crankcase
to
suction:
no
crankcase-suction pressure differential; and the com pressor
will have m axim um displacem ent. W hen the A/C capacity
d em and is low er and the suction pressure reaches the control
point, the valve will bleed discharge gas into the crankcase and
close o ff a passage from the crankcase to the suction plenum.
T he angle o f the w obble-plate is controlled by a force balance
on the five pistons. A slight elevation o f the crankcase-suction
p ressure differential creates a total force on the pistons
resulting in a m ovem ent about the w o b b le-p la te pivot pin that
reduces the plate angle.
T he com pressor has a unique lubrication system. The
crankcase-suction bleed is routed through the rotating
w obble-plate for lubrication o f the w obble-plate bearing. The
rotation acts as an oil separator, w hich rem oves som e o f the oil
from the crankcase-suction bleed, rerouting it to the crankcase
where it can lubricate the com pressor m echanism .

body to rem ove the clutch plate and hub assem bly
(Fig. 5).
R em ove the shaft key and retain for reassem bly.
Install or Connect
Install the shaft key into the hub key groove (Fig. 6).
A llow the key to project approxim ately 3.2 m m (1 /8 " )
out o f the keyway. The shaft key is curved slightly to
provide an interference fit in the hub key groove.
Be sure the frictional surface o f the clutch plate and the
clutch rotor are clean before installing the clutch plate
and hub assem bly.
A lign the shaft key w ith the shaft keyw ay and place the
clutch plate and the hub assem bly onto the com pressor
shaft.
NOTICE:
Do not drive or pound on the clutch hub or
shaft. Internal dam age to com pressor m ay result.
R em ove the J 3 3 0 1 3 -B rem over-installer center screw
and reverse the body direction on the center screw as
show n in Figure 7.
Install the clutch plate and hub installer J 3 3 0 1 3 -B w ith
bearing as show n in F igure 7.
The body o f the J 33013 -B installer should be backed off
sufficiently to allow the center screw to be threaded onto
the end o f the com pressor shaft.
