Pfaff 467 User Manual

The second possibility consists in dismantlingthe complete take-up leverassembly, including
the take-up link.
To do this, pull the lower oil tube off the nipple of shut-off valve V (Fig. 42) and drain the oil
into a clean vessel. Unscrew the oil reservoir back of the oil sight glass and detach from the
reservoir the oil tube conducting oil to the take-up link hinge stud.
To facilitate seizing the take-up link hinge stud, replace plug screw 1 (Fig. 34) by a M 4 set
screw. Loosen the three set screws that can be reached from above and pull the hinge stud,
together with the oil tube, forward out of the machine.
To dismantle the take-up lever assembly, loosen take-up crank set screws 3 and 4, as instructed
above, swing take-up link L down onto the take-up crank at its left position, and pull the
take-up assembly out of the needle bar crank.
When replacing the oil tube, check to see that the wick in the oil tube is not torn off and
extends beyond the oil holes in the take-up link hinge stud.
26. Changing the Needle Bar
To dismantle the needle bar, remove needle, needle plate, feed dog, bobbin case position
finger bracket and sewing hook. Loosen binding screws q and r inthe needle bar connecting
link (Fig. 34) and pull the needle bar down and out of the machine. In order to save the
time-consuming repetitionof timing the sewing hook and the mechanicalopener, it is recom
mended to loosen set screws p (Fig. 34) and g (Fig. 23) of needle bar frame S, screw z
(Fig. 34) in the take-up link, and take-up crankset screws 3 and 4 (Fig. 33). Swing away
take-up link Land pull the needle bar frame, together with the take-up lever assembly, out
of the machine. The needle bar can now be easily exchanged.
In replacingthe needle bar frame, take care that the needle is centered sideways inthe needle
hole exactly. Before you tighten set screws p and g securely, turn the balance wheel to make
surethe needle is centered correctly and the front-end parts work smoothly without having
any play. If necessary, adjust the position ofthe needle inthe needle hole in sewing direction.
To do this, loosen eccentric stud set screw g and turn out needle bar frame top set screw p.
Take a screwdriver and turn the eccentric stud underneath this screw to the right or left, as
appropriate.
