4 Lubricate lightly the bearing location in the
housing with clean engine lubricating oil. Put the
bearing on the bearing housing with the threaded
end of the shaft at the top. Put a suitable adaptor
on the outer ball guide of the bearing and press the
bearing into position on the shoulder of the bearing
housing.
To fit the bearing and shaft assembly into the
latest drive housing:
Clean the outer face of the bearing and apply a
narrow ring of POWERPART retainer (oil tolerant)
to the bearing in the position shown in (A2). Heat
the housing until the bearing and shaft assembly
can be fully fitted by hand, 130°/140°C
(266°/284°F); ensure that the housing is heated
evenly. Fit the bearing and shaft assembly into the
housing with the threaded end of the shaft at the
top. The assembly must be fitted in one movement
in less than three seconds or the retainer will
harden at this temperature. Clean excess retainer
off the bearing.
5 Fit the circlip (B4) correctly in its groove.
6 Put the spacer (B10) - Wabco 159 compressors
only - on the bearing (B7) and fit the keys (B6) in
the keyways on the shaft. A spacer is not used in
the latest drive assembly.
Note: The latest rear idler gear has a boss in place
of the spacer.
7 Ensure that the keys are aligned correctly with
the keyways in the gears (B3 and B11) and put the
gears in position on the shaft. The gear (B11) which
is used with Wabco 229 compressors has a boss
which must be towards the bearing when the gear
is fitted. When the latest gears are to be fitted on
the shaft, apply a narrow ring of POWERPART
retainer (oil tolerant) to the bore of the gears in the
position shown in (A1). Ensure that the boss of the
rear idler gear is toward the bearing when the gear
is fitted. Clean off excess retainer.
8 Turn the housing upside down and support the
outer gear. Apply pressure to the gear inside the
housing and press both of the gears into position
on the shaft.
