INSTALLATION OF BASES
WARNING: To ensure that drive is not unexpectedly started.
Turn off and lock out or tag power source before proceeding.
Failure to observe these precautions could result in bodily
injury.
Check mounting structure to insure it is rigid, level and well
supported. Position housing base on pedestal so oil gauge is
in position specified on construction drawing.
Do NOT tighten
housing base to pedestal.
Apply oil to the spherical seats of the housing base.
Set liner base in housing base.
Because of the closely controlled liner to housing fit, it may be
necessary to bolt the housing base down to allow the liner to slip
into the housing seat. Do a preliminary alignment check at this
time.
Make sure the two thermocouple/RTD holes in the liner
are aligned with the two thermocouple/RTD holes in the
housing.
Apply oil to the liner bearing surface.
NOTE: Liner has been machined to close tolerances.
Scraping of bore is not necessary.
INSTALLATION OF SHAFT AND
THRUST COLLAR
Inspect shaft to ensure it is smooth (32 micro-inch RMS or better)
and free of burrs and rough spots. Standard shaft diametrical
tolerance should be n.000/-.002” unless otherwise
specified on shaft detail drawing.
If bearing is non-expansion (fixed) type, check thrust collar for
burrs and scratches. Use crocus cloth (NOT emery) to smooth
any scratches on the thrust collar faces.
If clamp-on type thrust collar is used, make sure joints of collar
are clean. Place both halves of thrust collar into shaft groove
and tighten clamp screws alternately and evenly to torque value
specified in Table 1.
NOTE: Set and jam screws are shipped separately.
The collar faces must be smooth with no offset at the split.
