Prior to installation, heat the bearing as per the
procedure given further in this subsection.
This will expand bearings and ease installation. In-
stall bearings with groove as per exploded view.
552 Engine
Heat up the bearing(s) using bearing heater
(P/N 529 035 969). This will expand bearings
and ease installation. If required, put a suitable
plate or shim to avoid the direct contact between
integrated seal and the heating surface.

CAUTION: Bearing should not be heated to
more than 80°C(176°F). Do not heat bearing
with direct flame or heat gun or heated oil.
Inappropriate heating procedure(s) may cause
inner seal failure.
Turn bearing(s) several times during heating
process for heating it/them properly.
NOTE: Normally it takes approximately 10 min-
utes to heat up a bearing. So in the event of re-
placing a bearing, it is recommended to start heat-
ing it prior to removal. Two bearings can be heat-
ed at the same time on one bearing heater.

Touch the inner race of the bearing with the tem-
perature indicator stick (P/N 529 035 970). Stick
will liquefy when the bearing reaches the proper
temperature.
