Correct Chain Adjustment
,Chain ~ag
Lower machine from- its stand and engage neutral. With
the machine normally
loaded (1 person) and the suspen-
sion units
in "W" position the sag of the chain is correct
if you can lift it at least 63/64 in. through the inspection
hole
of the chain case.
If adjustment is necessary, slacken the knock-out spindle
nut, the hexagon nut on the eccentric adjuster (right-
hand side), and the hexagon nut on the leftchand side.
The
rear-wheel should then the pushed forwards or
backwards as required (taking care to maintain correct <
wheel alignment), until the Correct amount of chain ten-
sion has
been obtained. When re-tightening the nuts, see
that the eccentric discs do not slip out of position; they
should bear snugly against the anchorage at the fork
ends.
