MAINTENANCE
(cxontinued)
B. Reverse bars and reinstall Allen screws.
C. Whe the edges of the reversed impact bars become rounded (Figure 3), the bars must be replaced. See
below and Page 14.
8. The second point of wear is the clearance between the outer edge of the rotor and the inner diameter of the
sizing ring teeth (Figure 3).
If the space between the rotor and sizing ring has grown to 3/32”, (.094) and the impact bars are worn (rounded)
as shown in Figure 3, replacement of total rotor and sizing ring is advisable. See below and Page 14.
NOTE: If 3/32” space between rotor sna sizing ring is left to continue to increase, waste line stoppage may result as
increasingly large whole sections of waste will pass through sizing ring without breaking up.
When the rotor and sizing ring are new,
this spacing is 0.12” (less then 1/64”).
POINTS OF WEAR
FIG. 1
When these impact bars are reversed,
presenting new working sides, this
disposer will function well even though
this space may have grown to 3/32”.
At this stage of wear, no new parts
are needed.
With uniform wear on the rotor and the
teeth, spacing between has increased,
but the new faces of the reversed bars
restore efficiency.
These bars are badly worn and need reversing. FIG. 2
Remove Allen screws and reverse bars.
At this stage of double wear on bars,
this space may be 3/32” (.094). Check
with feeler gauge or U.S. Std. #13 gauge
wire.
At this stage, bars only may be
renewed–provided spacing between
rotor and teeth has not grown to 3/32”
and if waste line appears capable of
handling the slurry output.
These bars have had their double life. FIG. 3
With both sides well worn, it is evident that this disposer was
properly cared for, getting maximum length of service from all parts.
