liquid during the draining process. Clean out any
remaining solids by flushing with a hose.
BEARING TEMPERATURE CHECK
Bearings normally run at higher than ambient tem­
peratures because of heat generated by friction.
Temperatures up to 160
_F (71_C) are considered
normal for bearings, and they can operate safely to
at least 180
_F (82_C).
Checking bearing temperatures by hand is inaccu­
rate. Bearing temperatures can be measured ac­
curately by placing a contact‐type thermometer
against the housing. Record this temperature for
future reference.
A sudden increase in bearing temperatures is a
warning that the bearings are at the point of failing
to operate properly. Make certain that the bearing
lubricant is of the proper viscosity and at the cor­
rect level (see LUBRICATION in Section E). Bear­
ing overheating can also be caused by shaft
misalignment and/or excessive vibration.
When pumps are first started, the bearings may
seem to run at temperatures above normal. Con­
tinued operation should bring the temperatures
down to normal levels.
