Adjusting Bowl Runout
Bowl runout needs to be set if the bowl is removed. Adjust runout
with power off and drive chain disengaged. For runout specifica-
tions, see Chapter 1.
Step 1ÑGain Access.
Disconnect power and air. Remove the
cover from the exit area of the feeder.
Step 2ÑRemove Drive Chain.
Remove the master link. Discon-
nect the drive chain from the spindle shaft sprocket.
Step 3ÑAdjust Vertical Runout.
Attach a dial indicator to the
inside of the feeder frame. Set the indicator contact point vertical,
resting on the top of the rim of the bowl, up to
1
/
4
" (6 mm) from the
bowl's upper inside diameter (ID). Loosen the jam nuts and
locknuts (above and below) each arm of the bowl spider, one arm
at a time. Repeat as necessary while checking runout. Don’t tighten
the jam nuts until Step 4.
Do not adjust spider rim support arms without monitoring runout,
because if you misalign any one spider rim support arm, you may
damage the feeder bowl.
Step 4ÑAdjust Horizontal Runout.
Move the indicator contact
point horizontal, resting on the inner wall of the bowl, up to
1
/
4
" (6
mm) from the bowl's upper ID. Gently tap the bowl’s ID with the
palm of your hand or a rubber mallet. Inspect vertical runout and
adjust again if necessary. Continue alternating between horizontal
and vertical runout until both are within specification. Tighten
locknuts and jam nuts by hand firmly but not forcibly.
Step 5ÑCheck Exit.
Ensure that the proper relationship still exists
at each transition between the rim of bowl and output device
(deadplate, conveyor, gravity track or powered rollers, i.e.).
Step 6ÑCheck Backup Ring Clearance.
Ensure that the proper as-
tooled gap still exists between the bottom of the backup ring and the
rim of the bowl.
