2-6-4. Motor deceleration pulley assembly
If the tension of the belt is not appropriate, problems such as folding plate motor lock and jumping of the belt occur.
q Tighten the set screw with a torque of 0.69 Nm (7.0
kgf • cm), and secure the motor pulley at the position
shown in the figure.
w Check that a shim is inserted between the idler pulley
and E ring so that the thrust play becomes 0.1 to 0.3
mm (0.004" to 0.012").
e Apply a very small amount of oil to the area where the
idler pulley and fulcrum pillar are connected.
(Orelube G90-140)
r Apply a pressure of 3 N (306 gf) to deceleration
timing belt 1 using a tension gauge of 5 N (510 gf),
and check that the belt slacks by 2 to 3 mm (0.08" to
0.12").
t Apply a pressure of 3 N (306 gf) to deceleration
timing belt 2 using a tension gauge of 5 N (510 gf),
then move the motor deceleration pulley assembly
and adjust the tension of the belt so that it slacks by 2
to 3 mm (0.08" to 0.12").
