ECCENTRIC CAM SPINDLE
ADJUSTMENT
✰ The center distance adjustment of
gears is achieved by rotating the
eccentric sleeve and locking it on the
spindle by using M 10 lock nut once
the desired backlash is arrived.
✰ Ensure to hold the eccentric sleeve
by spanner while tightening the lock
nut which prevent the rotation of the
sleeve during tightening the lock
nut.
✰ The backlash is first adjusted
between pinion to exhaust gear and
then exhaust to inlet gear to get
effective backlash adjustment.
✰ The tightening torque for M10 lock
nut is 2 KG-M. This must be ensured.
