B. Service Instruction
18. The V-Belt Drive
When mounting the V-belt for the first time, care should be taken that it is not forced onto
the motor pulley because a distorted belt wears out rapidly.
The various motors used to drive the Pfaff 467 are standard motors conforming to German
DIN 42691 specifications. They are pivotally connected to the motor bracket by means of
a
hinge bolt and, after loosening nut Kl or a screw, can be swung to any position that may
be required to tension the belt correctly (Fig, 21).
Although the anti-friction bearings incorporated in the new high-speed seamers are designed
to withstand great stress and eliminate the risk of excessive heating or seizing of the machine,
we urge you to adjust the V-belt tension so meticulously that the belt Is neither too tight nor
too loose because both conditions may cause excessive wear.
There is no hard-and-fast rule for tensioning the V-belt, but it may be assumed that the belt
tension is correct, if you can compress the belt about % of an inch midway between both
pulleys.
Tighten the hinge bolt nut or the binding screw on the motor bracket so that it will not come
loose while sewing. A motor that hangs in the V-belt freely greatly reduces the service life
of the V-belt.
