Section 5: Axial Play Check and Adjustment
Axial or end play on shafting can result in noise, wear
and faulty sewing.
Check:
1. Check the main shaft by pushing and pulling on the
hand wheel.
NOTE: A small amount of main shaft axial play
is permissible. Too much main shaft play may
cause noise and/or stitching issues.

• Adjust so that minimal to no play is detected.
• Provisionally set the screws.

tightness, from the collar being too tight, by

(see counterweight timing page 17) .
