Check with a standard thermometer. Sleeve
bearings that are running too hot probably
have too much 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
During the quarterly lubrication change, check
the clearances. Normal clearance is
0.002 inch (51 ), plus 0.001 inch (25 ) for
each inch (25 mm) of the shaft-journal
Make sure that the oil rings are free to turn
with the shaft. Repair or replace oil rings when
Each year, when the pump is dismantled,
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.
