3 .Belt and Idle Arm
1.When the Belt (54) falls off, refer to step 4 in item 1 to disassemble Chain Covers and Idle Arm (10),
referring to step 5 in item 1. Then refer to steps in item 1 to resume the Belt and check the running of
the belt at low speed to investigate the swing of the Drive Pulley (20) and the Belt (54) and the
alignment of the Belt (54), Drive Pulley (20) and Generator Flywheel. Make sure they are in line. Then
test the running of the belt at speed as high as100 – 120 RPM and investigate with a sudden stop, as the
way in the assembly line. If everything is normal, resume and secure the Chain Covers. The
falling-off of the belt is normally caused by misalignment among the Belt (54), Drive Pulley (20) and
Generator Flywheel. When there is misalignment, the belt shifts from one side of the Drive Pulley to
the other when it changes orientation of the running and the determination of the part, which is
misaligned, is required. The Idle Arm (10) must be replaced if it is misaligned.
Slippage: Tightening M8x7T Nut (88) on M8 x 170J-Bolt (87) will fix the problem.
