20. Setting the Needle Bar at Correct Height
The needle and hook motions must be properly synchronized in order to obtain a perfect
seam. The proper timing of both motions requires utmost accuracy.
Correlating the needle and hook motions so as to ensure proper loop formation normally is
referred to as "adjusting the needle rise".
If the amount of needle bar rise must be reset, for instance, after the needle bar has been
exchanged, begin by roughly setting the needle bar to the correct position as follows: Loosen
the needle bar set screw, move the needle bar connecting link to its lowest position, and set
needle the bar so that its bottom end is about Va", or 13.0 mm, above the top surface of the
needle plate (Fig. 22).
The amount of needle rise required to form the loop on Pfaff 467 machines, i.e. the distance
by which the needle has to rise from the lowest point of its stroke, normally is about Vi6",
or 1.8 mm.
To set this amount correctly, it is recommended that you use the all-purpose gauge supplied
by us (Order No. 91-129 604-01).
Turn the balance wheel until the needle bar has reached the lowest point of its stroke. Slip
the gauge onto the needle bar, pushing it against the lower needle bar bushing. Place clamp
No. 880137/00 on the needle bar, push it up against the gauge and screw it down (Fig. 23).
This done, pull out the gauge and cautiously turn the balance wheel in sewing direction until
the clamp strikes the needle bar bushing. Now begin to time the sewing hook,
