Disassemble the machine
3.1
Disassemble the main shaft (Fig. 1 and Fig. 2)
Before disassembling the main shaft, it is advisable to mark the exact position
of each part or screw, and to take the measures of both bearing support blocks
by means of a gauge, measuring from the front edge of the machine column.
(Measures a + b).
This will save you a lot of time when you assemble and adjust the machine.
(Fig. 1)
Not until now should the screws of the parts attached to the shaft be loosened
and the right handwheel be removed and the shaft, too, be pushed out to the
left by a withdrawal device.
Loosen the screws of the parts. Take off the right hand wheel. Pull the shaft
about 20 to 30 mm to the left and remove the remaining glue without displacing
the ball bearings. Then take off shaft.
The left handwheel with the stitch-regulating eccentric bolt does not need to be
removed.
Be sure
that the set screws 176.0632 located on both sides of the
regulating eccentric bolt (A) 132.0074 are removed; on machines that were built
before 1986, the screws 176.0620, 176.0619, and the setbolts 135.0078.
(Fig. 1 and Fig. 2)
NOTE!
If not done yet, mark the position of guide disc 153.0031 and
regulating eccentric 132.0074.
The remaining glue can easily be removed from the shaft by using a cleanser,
e. g. Clorothene.
