6-7 Hook driving shaft coupling and the lateral timing of the hook driving shaft
Adjustmentprocedure
1.Positiontheatsectionofthehookdrivingshaftsetscrewandthegrooveinthecouplingsothattheyare
in parallel with each other. (Fig. 1)
(Right and left couplings (Fig. 2))
2.Wheninstallingthehookdrivingcams,adjustthetimingoftherightandlefthookdrivingshaftssothatthe
timingbetweentherightandleftfeedrockcamsisoppositetoeachother.(Fig.3)
3. At the center of the right and left hook driving shafts, tighten the coupling setscrew so that there is no
backlashinthethrustdirectionofthecoupling.(Fig.4)
(Caution) When tightening the setscrew, take care not to allow the coupling to move out of alignment from
the at section of the shaft. In addition, carefully conrm the timing of the right and left hook
driving shafts.

Flat section
Install so that the timing between the cams becomes opposite.
(To correctly position the cams, place pin on the hook driving shafts)
