C.1 M660BU/BUL_MAIN BODY
1) For M660BUL, turn off the unit power at the switch and then unplug the line cord at wall outlet.
2) Remove the CENTER FOOT_UP (61) by removing two bolts (52) securing the CENTER
FOOT_UP (61) to the Main Body Frame.
3) Remove two bolts (55) securing MAIN BODY CAP (54) to the Main Body Frame.
4) Lift the MAIN BODY CAP (54) and SEAT POST CAP (56) and then fix these to the Gas
Cylinder temporarily by a tape to make it easy to remove the MAIN BODY_R (50).
5) Remove five bolts (51, 52) securing the MAIN BODY_R (50) to the Main Body Frame and
remove the MAIN BODY_R (50).
6)
Mark the position of HEX LOCK NUT (17) on HANGER BOLT (16) for restoring BELT
tension when reassembling it.
7) Loosen HEX LOCK NUT (17) by using 13 mm spanner until it reaches the end of HANGER
BOLT (16) to slacken POLY V-BELT (46).
8) Remove POLY V-BELT (46) from PEDAL PULLEY (28), IDLER PULLEY (8) and
GENERATOR PULLEY. Be careful not to get your hands be caught between the BELT and
PULLEYS.
9) Remove IDLER BRACKET (7), IDLER BRACKET SPACER (12) and IDLER BRACKET
BUSH (13) by removing three bolts (14) securing these to the GENERATOR.
Note
If you find IDLER BRACKET SPACER (12),
discard both IDLER BRACKET SPACER (12) and
IDLER BRACKET BUSH (13) and new IDLER
BRACKET BUSH (13) should be used for reassembling.
If no IDLER BRACKET SPACER (12), the removed
IDLER BRACKET BUSH (13) should be used for
reassembling.
10) Install new IDLER ASEMBLY on the GENERATOR
by using three bolts (14) and IDLER BRACKET BUSH
(13).
Do not tighten three bolts (14) too strongly
because it can spoil the threads of GENERATOR
plate.
IDLER BRACKET SPACER (12) should not be installed.
