2)
Remove the shoe, and the driving roller will be exposed.
3)
Use the spanner 10 to fix the hexagon point of pulley
8.5-45.1 and turn the driving roller in the direction
whereby anti-clock wise screw can be loosened, and
either of the pulley 8.5-45.1 or driving roller is
loosened and then removed.
4-A) If the pulley 8.5-45.1 has been successfully removed,
A-a)
Loosen the 4 pieces of tapping screw PT4x25 for
mounting the bracket to remove the bracket.
A-b)
Insert the lock nut wrench 20 through the two
holes on the helical gear 31, fix the helical gear
31, and then turn the driving roller in a direction
whereby the left-handed screw can be loosened.
A-c)
If the ball bearing 626 and driving roller have been successfully removed, use the resin hammer to
slightly hammer the helical gear 31 complete from the direction of ball bearing 626 mounting side to
remove the helical gear 31 complete.
4-B) If the driving roller has been loosened and successfully removed along with the ball bearing 626,
B-a)
Set the spanner 10 on the hexagon point of pulley 8.5-
45.1, insert the spanner 7 in the two faces on driving
shaft, and then turn them in the direction whereby the
