recommendations) through the breather vent (405) until
oil can be seen in the center of the oil view sight (143)*.

*Constant Level Oiler. If equipped with a constant
level oiler, fill reservoir with oil, place thumb over spout,
invert and screw reservoir into upper casting. Allow
reservoir to empty, filling the bearing frame (Figure 10).
Several fillings of the reservoir may be required before
the actual oil level is reached. To avoid adding too much
oil, never finish filling oil in bearing frame (99) through
the vent breather (405) at top of the bearing frame.
Never use lower casting only as a fill spout, always fill
thru reservoir. When oil level is reached, no more oil will
run out of the reservoir bottle. Use constant level oiler's
glass sight to check oil level in bearing frame. When oil
level is reached tighten the three setscrews on the side
of the upper oiler. The constant level oiler (143) should
be topped up as required during operation.

B. LUBRICATION OF MOTOR BEARINGS. See
motor manufacturer’s instructions to be sure motor
bearings are properly lubricated.
C. TORQUE VALUES. Refer to Table 14,
Recommended Torque Values. Clean and properly
lubricate threads and bearing face of the fastener to
obtain the proper fastener loading from these torque
values. Fasteners should be tightened evenly and in
stages with a criss-cross bolt pattern. Refer to your
torque wrench manual for the proper use of your
wrench.
Refer to the pump nameplate to determine your pump
model for tie rod torques.
The first bearing jam nut (22) is to have 20 ft-lbs torque
while holding the coupling end of the shaft. The second
bearing jam nut is to be tightened to 30 ft-lbs while
holding the coupling end. Loctite the second bearing jam
nut.
Table 14. Recommended Torque Values (ft-lbs)
315 / 50 ft-lbs increments
446 / 50 ft-lbs increments
