Regalia Service Manual
Hook-shaft timing pulley
Tools needed: 2.5 mm handle hex tool
NOTE: The hook-shaft timing pulley rotates in
the opposite direction as the main shaft timing
pulley. Carefully NOTE the labeled first screw.
NOTE: The hook-shaft collar normally does
not have a flat, but on the Regalia machines
it does; however it is not for timing. The hook
shaft pulley first screw is fixed on another
hook shaft flat.
Important Hook-Shaft NOTEs
The hook-shaft turns two times per stitch and rotates
in the opposite direction as the main shaft. Please
carefully NOTE which screw is the first screw in the
direction of motion and on the flat.
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 to remove ax-
ial play, not the hook-shaft pulley. The setting can be
thrown off, which may make needle-to-hook distance
adjustment impossible.
The Regalia utilizes long collars with two screws in line
to help prevent the collar from tipping when tight-
ened, causing variation of tightness or play, as the
collar rotates 360°. To ensure that there is no tight-
ness or play, the collar should be checked through a
full rotation until it has minimal tightness and
minimal play .
Section 4: Checking and Securing Flats and Screws
First Screw, First Position Rule
The first screw is 120 degrees before the 2nd screw
when the handwheel is turned in the direction of
