< 4 > Mounting V-pulleys and poly V-belt
(1) Mount V-pulley 9-23L to the threaded portion of spindle by turning anti-clockwise with your hand.
But be careful, not to tight it too strong. And then, fix the V-pulley 9-23L with hex nut M10x17.
The hex nut M10x17 has to be turned anti-clockwise for fastening. But fasten the hex nut not strong
in this stage. See Fig. 4.
(2) After inserting key 4 to the grove of drum shaft, mount V-pulley 9-39.7 to the drum shaft aligning its cut portion
to the key 4. And then, fix the V-pulley 9-39.7 with hex socket head bolt M6x12.
The hex socket head bolt M6x12 has to be turned clockwise for fastening. But fasten the hex socket head bolt
not strong in this stage. See Fig. 4.
If you use the used hex socket head bolt M6x12,
apply the adhesive to the threaded portion of the bolt,
or use the fresh one.
