Sleeve bearings
Check with a standard thermometer. Sleeve
bearings that are running too hot probably
have too much lubricant.
Q
Change lubricant
Change lubricant according to Table 14). If
lubricant change does not solve the
overheating problem, disassemble and inspect
the bearing. If the bearing is in good
condition, check the pump and motor
alignment.
Check clearances
During the quarterly lubrication change, check
Q
the clearances. Normal clearance is
0.002 inch (51 ), plus 0.001 inch (25 ) for
each inch (25 mm) of the shaft-journal
diameter.
Make sure that the oil rings are free to turn
with the shaft. Repair or replace oil rings when
necessary.
Check bearing
Each year, when the pump is dismantled,
A
condition
check the condition of the bearings and the
bearing race; replace as necessary. Sleeve
bearings are usually split-type and can be
easily removed and installed. Rotation of the
bearing is prevented by a pin in the top half of
the bearing housing.
(1) M-Monthly; Q-Quarterly; A-Annually.
