a. The housing must be heated to a temperature of ap-
proximately 212" F (100" C) in an oven or on a hot
plate. Check to see that it is at the proper tempera-
ture by dropping tiny drops of water on the case; if
they sizzle and evaporate immediately, the tempera-
ture is correct. Heat only one housing at a time.
CA UTION
Do not heat the housing with a torch (pro-
pane or acetylene)-never bring a flame
into contact with the bearing or housing.
The direct heat will destroy the case harden-
ing of the bearing and will likely warp the
housing.
