Axial Play Check and Adjustment
Axial or end play on shafting can result in noise, wear, and
faulty sewing.
Tools required: (2, and 2.5mm handle Allen)
Check:
1.
Check the arm-shaft by pushing and pulling on the
hand wheel. See Figure 18. If a correction is
necessary:
•
Loosen the thrust collar (See Figure 19)
•
Adjust so that no play is detected.
Care must be
taken on the first screw that is fixed on an
inclined flat so as not to tighten too tight at
first.
•
Provisionally set the first screw, tighten the
second screw fully tight.
•
Tighten the first screw.
2. Check the transmission shaft by pushing and pulling
axially on the gear as shown in Figure 20. If a correct
is necessary:
•
Loosen the 2nd screw on the gear first and use
the first screw (on the flat) to adjust any play by
moving the gear outwards towards the bushing.
•
Tighten the first screw on the flat and then
tighten the second screw.
3. Check the hook shaft by pushing and pulling the
hook as shown in Figure 20. If a correction is
necessary:
•
Remove the play by loosening the hook shaft
thrust collar and adjusting out any axial play as
shown in Figure 22. (
Note: No shaft flat is located
here.)
