The hook-shaft pulley is set to a specific setting from the end of the shaft to allow proper needle-to-hook
distance adjustment. Adjust the collar (not the hook-shaft pulley) to remove axial play, or the setting can
be thrown off, which may make it so the needle-to-hook distance cannot be adjusted properly.
The Janome QMP16SU utilizes long collars with two screws in line to help prevent the collar from tipping
when tightened, causing variation of tightness or play, as the collar rotates 360º. To ensure that there is
no tightness or play, the collar should be checked through a full rotation until it has minimal tightness and
minimal play.
Adjust if necessary
Tool:
1. Remove the front cover.
2. Remove the play by loosening the hook-shaft
thrust collar (not the hook-shaft timing pulley)
and adjusting out any axial play.
NOTE: The hook-shaft thrust collar normally
does not utilize a flat on the shaft.
3. Rotate the shaft through a few 360° rotations to
ensure you have adjusted properly to remove
the axial play.
