bearing chills, it will tighten on the shaft, so install it quickly. Make sure the bearing is
installed completely.
2. Follow this step when installing a bearing in a housing. Bearings are general installed in a
housing 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:
CAUTION
Before heating the housing in this procedure, 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
℃
(212°F) in an oven or on a hot plate. An easy way
to check that it is the proper temperature is to place tiny drops of water on the housing; if
they sizzle and evaporate immediately, the temperature is correct. Heat only one housing at
a time.
CAUTION
Do not heat the housing with a propane or acetylene
torch. Never bring a flame into contact with the
bearing or housing. The direct heat will destroy the
case hardening of the bearing and will likely warp
the housing.
b. Remove the housing from the oven or hot plate, and hold onto the housing with welding
gloves. It is hot!
NOTE
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
bearings in the housing.
d. Before heating the bearing housing, place the new bearing in a freezer if possible. Chilling'
a bearing slightly reduces its outside diameter while the heated bearing housing assembly
is slightly larger due to heat expansion. This makes bearing installation easier.
NOTE
Always install bearings with the manufacturer’s
mark or number facing outward.
e. While the housing is still hot. Install the new bearing(s) into the housing. Install the bearings
by hand. if possible. If necessary, lightly tap the bearing(s) into the housing with a driver
placed on the outer bearing race (

). Do not install new bearings by driving on the
