2. Follow this step when installing a bearing in a
housing. Bearings are generally installed in a hous-
ing with a slight interference fit. Driving the bearing
into the housing using normal methods may damage
the housing or cause bearing damage. Instead, heat
the housing before the bearing is installed. Note the
following:
Before heating the housing, wash the
housing thoroughly with detergent
and water. Rinse and rewash the cases
as required to remove all traces of oil
and other chemical deposits.
a. Heat the housing to approximately 100° C
(212° F) in an oven or on a hot plate. To check
the housing temperature, fling tiny drops of
water onto the housing. If they sizzle and
Socket
evaporate immediately, the temperature is
correct. Heat only one housing at a time.
Do not heat the housing with a pro
pane or acetylene torch. Never bring
a flame into contact with the bearing
Bearing or housing. The direct heat will de
stroy the case hardening of the bear
ing and will likely warp the housing.
b. Remove the housing from the oven or hot
plate, and hold onto the housing with a
kitchen potholder, heavy gloves or heavy
shop cloth. It is hot!
Remove and install the bearings with
a suitable size socket and extension.
c. Hold the housing with the bearing side down
and tap the bearing out. Repeat for all bear-
ings in the housing.
d. Before heating the bearing housing, place the
new bearing in a freezer. Chilling a bearing
slightly reduces its outside diameter while the
Driver
heated bearing housing assembly is slightly
Spacer
larger due to heat expansion. This will make
bearing installation easier.
Bearing
Always install bearings with the man
Housing ufacturer's mark or number facing
outward.
e. While the housing is still hot, install the new
bearing(s) into the housing. Install the bear-
ings by hand, if possible. If necessary, lightly
tap the bearing(s) into the housing with a
socket placed on the outer bearing race (Fig-
ure 47). Do not install new bearings by driv-
ing on the inner bearing race. Install the
bearing(s) until it seats completely.
