NOTE Bearing mandrel must be pressed against
the lettered end of bearing shell. Take care
that the housing bore is square with the
press base and the bearing is not cocked
when pressing a bearing into the housing.
CAUTION If the bearing mandrel specified in the
“Tools and Materials Required for Servic-
ing” section is not available and alternate
methods are used to press in bearing (15)
or (22) be careful to ensure that the
bearing depths specified are achieved to
insure adequate bearing support and
correct relationship to adjacent compo-
nents when assembled. SEE FIGURE 24.
CAUTION Because bearings (15) and (22) have a
press fit into the housing they must be
discarded when removed. They must not
be reused.
Press in inner
bearing
2. The Large Frame TK Series Torqmotor
housing (21) requires that you assemble a
new backup washer (19), new seal (18), with
the lip facing to the inside of Torqmotor (see
figure 45), new thrust washer (16), new
thrust bearing (17) and a new second thrust
washer (16) in that order before pressing in
the inner housing bearing (15). SEE FIGURE
25 & 26. When these components are in
place, press new bearing (15) into the
housing (21) to a depth of .130/.150 inches.
Use the opposite end of the bearing mandrel
used to press in outer bearing (22). Reference
figure 1, in the “Tools and Materials Required
for Servicing” section. SEE FIGURE 27.
