1) Removing oil seal sleeve
Hold a flat cold chisel at right angles to the
sleeve and cut the sleeve at three places to
loosen it, as shown in the illustration. If it is
impossible to remove the sleeve in this
method, hold the chisel in the axial direction
and lightly tap the sleeve to loosen it.
CAUTION
Be extra careful not to cause damage to the
crankshaft when removing the sleeve.
2) Installing oil seal sleeve
Apply oil to the inside of an oil seal sleeve
and, using crankshaft sleeve installer set
(30691–13010), install the sleeve in position,
as shown in the illustration.
CAUTION
Be extra careful not to cause damage to the sleeve
when installing it.
When the oil seal sleeve is worn after the
engine has been operated, replace both oil
seal and oil seal sleeve.
