G. Assembly of Housing Parts
NOTE
If a new shaft bearing (61), shaft (48), valve block
(26), or housing (27) is required, a complete preload
adjustment must be performed. If the same parts are
returned to service, the preload adjustment can be
omitted. The same procedure applies to yoke (56) and
its associated bearings.
1. If the shaft bearing (61) requires replacement, install a
new bearing race (62) into housing (27). Use tool shown in
Figure 11 to press bearing race in place. Make sure the bear-
ing race (62) is oriented properly to accept the roller bearing
before pressing into the housing. The race must be bottomed
against the shoulder of the housing at completion of press.
2. Place housing (27) on a flat surface with the shaft
seal end down. Lay the front shaft bearing (61) into the race.
Install yoke spring (60) and seat (59) into the housing.
3. Position the yoke pintle properly and install yoke into
housing. Assemble the yoke bearings, races, and spacers as
follows.
