6.4 BELT ADJUSTMENT AND
REPLACEMENT
The belts on your new unit have been properly
adjusted at the factory. However, before operating, it
is suggested that belts be checked and re-adjusted if
necessary. Recheck belts several times in the first
days of operation and at least twice a month for the
following six months. Thereafter, belts should be
checked at each greasing. The drive used on this
unit is equipped with banded belts and matching
sheaves which transmit much higher horsepower per
belt than older type belts.
Because much higher tension is required, it is
advisable that the tension be checked with a tester
or springs scale (see Figure 14).
To adjust belts, loosen bolts on motor mounting
plate, adjust tension screws on adjustment bracket in
or out (depending on desired adjustment), then re-
tighten bolts on motor mounting plate.
Do not over tighten. Too much or too little tension will
damage the drive belts and bearings. Check the
tension frequently to be sure the deflection is at the
value determined.
To replace worn belts, loosen bolts on motor
mounting plate and remove tension screws so the
old belts can be removed from the sheaves. Remove
the tension bracket and the bolts from the upper
bearing bracket. Rotate the bracket 90° and remove
old belt. Put new belt on and reverse the
disassembly order to re-assemble.
Replacement belts should be ordered and installed
in complete matched sets or one banded belt.
Include old belt number(s) when reordering.
6.5 AFTERFILTERS
The afterfilter bags on the Cyclone Dust Collector
are semi-permanent and will give you long, efficient
service if you perform routine maintenance.
After each day’s operation, shake the filter bag(s)
vigorously to remove the clinging material. If the
afterfilter bag has a zipper-closed bottom, always
empty the bag after shaking. For C-Series afterfilters,
open slide gates before shaking bags so dust can
fall into drums. Close slide gates after cleaning is
completed. Care should be taken to prevent tearing
or puncturing the filter fabric.
When adequate air volume cannot be restored by
shaking the bags, simply remove them and replace
with new filters. Under normal operating conditions,
afterfilter bags should be replaced every two years
for best performance. Be sure to include the model
and serial number of your cyclone dust collector
when ordering replacement afterfilter bags (see
Specification Table in Section 4.4).
