Inspection: Bearing housing
• If the measurement exceeds the specified limit, replace the
bearing housing.
Installation procedure
Installation: Thrust bearing
• Install the shaft and turbine wheel unit, fitted in the bearing hous-
ing, in the turbine housing. Fasten it in place temporarily with the
coupling.
CAUTION
• When installing the shaft and turbine wheel unit, make sure
that its blades are not damaged by striking the turbine
housing because they are easily bent.
• Fit the thrust bearing onto the shaft and turbine wheel unit.
CAUTION
• Before installing the thrust bearing, wipe off dirt and oily
substance completely from the stepped area of the shaft
and both sides of the thrust ring using dry tissue paper or
the like.
Installation: Insert
• Fit the piston ring onto the thrust sleeve, then fit it into the insert,
its end gap first, taking care that it is not damaged.
CAUTION
• When fitting the piston ring, use care not to open it exces-
sively or twist its end gap portion.
• Fit necessary parts in the insert first, then fit the insert into the
bearing housing.
CAUTION
• Before installing the insert, wipe off dirt and oily substance
completely from both end faces of the thrust sleeve using
dry tissue paper or the like.
Installation: Snap ring
• Place the snap ring in the bearing housing in the illustrated di-
rection using a pair of snap ring pliers.
• Then, using a screwdriver, tap the snap ring at its break ends
into place in the mating groove of the bearing housing.
CAUTION
• Fit the snap ring while holding it with your hand to prevent
it from springing off.
