TIP:
• Since the diameter of the passage in the
lower case and the diameter of the special
service tool

the special service tool may not fit into the
lower case. In that case, use a special ser-
vice tool with a smaller diameter.
• Make sure to remove the forward gear
before removing the needle bearing.
