Motors with sleeve bearings may be manufactured
with ¼ or ½ inch end movement (float) in the motor
rotor. For limited end-float arrangement, the gap
between the coupling halves must be set in a different
manner. If specific directions are not indicated in the
motor instructions, the following is applicable.
NOTE: If the driver is mounted at Truflo, the setting
for the coupling will already have been determined.
1-Slide the rotor towards the outboard end of the motor as far
as it will go and mark the shaft at the motor frame (Fig. 13).
2-Slide the motor rotor towards the inboard end of the motor as
far as it will go and mark the shaft again. The distance between
marks should be either ½ or ¼ inch if the motor is arranged for
limited end-float travel.
3-Scribe a third mark on the shaft half way between scribe
marks made in (a.) and (b.) above.
4-Clamp the rotor in place.
5-Move the motor as a unit towards the pump until the end of
the motor shaft is the correct coupling “spacer” distance from
pump shaft.
4. Install coupling guard. Refer to coupling guard
installation instructions in
Appendix II .
LUBRICATING BEARINGS
Bearings must be lubricated properly in order to
prevent excess heat generation, sparks and premature
failure.
Ring Oil Lubrication
Ring oil lubricated ball bearings are standard on Model
TSMP units. Sleeve/ball bearings are optional. Bearing
housings are supplied with constant level oilers and sight
glasses.
NOTE: See Preventive Maintenance section for
lubrication recommendations.
Assure that oil rings are properly located as described in
Disassembly & Reassembly section.
1-Install and lubricate coupling per manufacturer’s
instructions.
2-Check angular and parallel alignment of coupling halves
using a dial indicator and a feeler gauge. See
Alignment and
Alignment Criteria in Operation Section.
�
CAUTION
The bearings are NOT lubricated at the factory. (See
Maintenance of Bearings in
Preventive Maintenance
Section.)
