(2) Take care not to twist O-rings. Correct by your finger if it is twisted.
(3) Take care not to damage seals when inserting.
(4) Handling of floating seals :
• Completely wipe off all the oil from the O-ring and housing after detaching the floating seals.
• Before installing, apply a little gear oil to the matching face of the housing.
• Turn the seals two or three times after installation to break them in.
(5) Apply grease to the lip of the oil seals to prevent wear.
