6. Replacing oil seals

1. If there are burrs, scratches, or rust on the inner
surface of the housing hole, the chamfered part, or
the surface of the shaft through which the oil seal
passes, remove it with sandpaper.
NOTE
• If there is a risk of splines or key grooves of
the shaft damaging the lip part of the seal,
wrap masking tape around those parts to
protect the seal.
2. Clean the inner surface of the housing hole and the
surface of the shaft.
3. Lubricate the seal lip and dust lip.
NOTE
• If the seal has a dust lip, grease the gap
between the lips to prevent dry wear that
occurs when the machine starts.
• Use the specified grease or oil to lubricate
the lip.
4. With the seal lip facing the airtight side (B) of the
object, use a press to press-fit the oil seal until it is
fixed to the boss.
NOTE
• In cases when installing an oil seal without a
press, place a wooden board on the seal
and gently tap the board with a hammer;
install the oil seal straightly and evenly.

• Connect the battery terminals after removing dust,
old grease, blue rust and others.
