Test left to right
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.
If a correction is necessary:
• Remove the front cover .
• Loosen the counterweight screws
(3 mm handle Allen)
• Adjust so that minimal to no play is detected.
• Provisionally set the screws.
• Check that the shaft has minimal play and no
tightness, from the collar being too tight, by
rotating the shaft through a few 360
• Check that the timing of the eccentric is still correct
(see counterweight timing page 17) .
• Fully tighten the screws.
• Check shaft again for play or tightness.
2. Check the hook shaft by pushing and pulling
the hook.
If a correction is necessary:
• Remove the front cover .
• Remove the play by loosening the hook-shaft
thrust collar (not the hook-shaft timing pulley) and
adjusting out any axial play.
• Check for proper setting by rotating shaft through a
few 360 rotations.
