After all components have been assembled, the space remaining up to the lock washer is taken up by
inserting shim washers. Then slip on the snap washers.
When the roller is correctly assembled, the fluted discs between the spacers can only just be freely
rotated. The components must not rub against each other but, at the same time, there should be as little
play as possible.
When checked against the light, the gap should only just be visible.
Functional Test
After installation, the roller must be tested for proper operation and true running. For this, switch on the
roller as described under ‘Torsion Test’.
The drive motor must run uniformly ‘true’. No sluggish points must be audible.
1. Remove bearing housing and determine if housing is distorted compared to the meter roller. If
housing has a small gap in the front and the back of the meter, adjust the nuts on the stiffening
rods on the bottom of the metering unit 1/4 - 1/2 turn until the meter roller can be removed and
installed freely with very little resistance.
NOTE: The nuts on the very bottom of the stiffening rods are Nylock nuts. Do not adjust the nuts
more than ½ turn when adjusting the housing.
2. If gap is on top and bottom of meter housing, turn the nuts so they move up on the stiffening rods
until the meter roller is removed and installed with very little effort.
