9. Apply 3 or 4 drops of Loctite sealant at top of thread
for each of four holes in housing.Do not allow parts
with Loctite applied to come in contact with any
metal parts other than those for assembly. Wipe off
excess Loctite from housing face, using a non -
petroleum base solvent.
Do not apply Loctite to threads more than 15 min-
utes before installing screws. If housing for more
than 15 minutes, repeat application. No additional
cleaning or removal of previously applied Loctite is
necessary.
10. Before installing flange and seal assembly over
shaft, place protective sleeve or bullet over shaft.
Then lubricate space between exclusion seal and
pressure seal, as well as lips of both seals.
Install flange. Rotate flange slowly while pushing
down over shaft. Be careful not to invert or damage
seals.
11. After removing bullet, clamp motor in vise as shown
in Figure 2-49. Make sure shaft cannot fall out. Install
dry screws and alternately torque them immediately
to 250 in-lbs (28 Nm). If you use primer, allow to cure
for 10 to 15 minutes. Without primer, allow 6 hours
curing time before subjecting motor to high torque
reversals. On all other applications, you can run
motor immediately.
If you use new screws, make sure they are the cor-
rect length: 7/8 in. (22mm) under head length. See
parts list for correct part number.
Gerotor End
