TO REMOVE THE ARM SHAFT CONNECTION BELT
FROM WITHIN THE ARM
Slide the connection belt off the lower belt pulley; remove the machine
pulley. loosen the three screws in the arm shaft bushing near the machine
pulley' and remove the bushing; lift the belt up through the arm cop hole
as far as possible and draw it out through the space normally occupied by
the bushing.
Owing to the fact that the sewing hook makes two revolutions to one
revolution of the hook driving shaft, and that the feed lilting eccentric
is on the hook driving shalt, it is possible to have the sewing hook
correctly timed without having the feed correctly timed. To overcome
this, the plate (F2, Fig. 24) is attached to the underside of the bed of the
machine. This plate is marked with on arrow at its lower end and directly
alongside of the plate is the collar (G2, Fig. 24) mounted on the hook shalt,
which is also marked with an arrow. Alter replacing the belt over the
upper pulley, replace the arn1 shalt bushinq and securely fasten it in position
by its three screws; replace the machine pulley. With the belt on the
upper pulley, turn the machine pulley from you until the thread toke- up
lever is at its highest point. Then turn the hook shalt with the fingers
until the two arrows, one on the plate (F2) and the other on the collar
(G2), ore directly in line. Now, without disturbing either the arm shaft
or the hook shaft, slip the belt over the lower pulley. The feed will then
be correctly timed with the needle bor.
