it while fixing the fan 60 for cooling the motor. (Note) Since the fan 68 is mounted with anti-clock wise � screw, turn in clock wise to remove. 6) Remove the scroll plate. 7) Use the resin hammer to slightly hammer the armature shaft from the commutator side to disconnect the armature. (2) Disassembling of gear 1) In the same manner as replacing of armature, remove the housing R, belt cover and synchro belt 6-300. 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, Loosen the 4 pieces of tapping screw PT4x25 for mounting the bracket to remove the bracket. A-a) 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-b) 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. A-c) 4-B) If the driving roller has been loosened and successfully removed along with the ball bearing 626, 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 right-handed screw can be loosened, and the pulley 8.5-45.1 can be removed. B-a) Loosen the 4 pieces of tapping screw PT4x25 for mounting the bracket to remove the bracket. B-b) 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.
