from the bearing housing.
20 Remove the two case drain plugs and o-rings from the bearing
housing.
21 Remove the bearing housing from the vise and turn it over so the
output shaft is on top.
22 The drive spacer may fall out of the output shaft (see Figure 10).
Watch for it! This spacer must be reinstalled when the motor is
reassembled.
Note: Some motors do not use a drive spacer.
23 Clamp the bearing housing in a vise so the output shaft is on top
(see Figure 11). Protect the bearing housing with soft vise jaws, wood,
or hard rubber. Use just enough clamping force to hold the bearing
housing securely while the retainer is removed.
24 Remove the eight cap screws that hold the retainer to the bearing
housing.
25 Carefully pry the retainer loose with a small blade screwdriver.
Do not damage the mating surfaces of the retainer or bearing housing.
26 Remove the 89 mm [3.5 in.] o-ring from the retainer.
27 Use a small blade screwdriver to pry the quad ring seal and back-
up washer from the retainer. Be careful not to damage the seal seat.
28 Turn the retainer over and pry out the dust seal with a small blade
screwdriver. Be careful not to damage the seal seat (see Figure 12).
29 Remove the output shaft.
30 Remove the thrust bearing and two thrust washers from the output
shaft.
31 Remove the bearing spacer.
Note: The shaft bearings are pressed into the bearing housing and
should not be removed. If the housing or bearings are damaged the
complete assembly must be replaced.
