GBA20 Power Shuttle
Fixed unit
The fixed unit (1) has two functions:
- it receives the low pressure supplying the forward
clutch via the pipe (74),
- it acts as casing for the clutch lubricating and cooling
pump.
The pipes (31) connecting the pump housing (1) and
the cover (38) lubricate the reverse clutch braking
device.
The shims (3) located between the closing spacer (4)
and the fixed unit (1) provide end play for the forward
clutch.
Drive transmission
Drive from the Power Shuttle is transmitted to a
mechanical unit located in the rear compartment of the
input box.
This element comprises a secondary shaft (1) which is
secured to the pinion (2) by splines
The shaft is fitted on two taper roller bearings "R", and
is carried by two bearings of the input unit.
The shims (3) (Fig. 1) fitted between the cover and the
unit are used to preload the bearings.
