SERVICING YOUR SUPERBRUSH 17
(outboard) brush support casting (Fig. 15) must
both be set at the proper height along the column
tubes so the height adjusting screws provide for
proper miter gear alignment. Before adjusting these
parts, tighten one set screw in the table support
castings (Fig. 5) to hold the height adjusting screw
in position during adjustment.
Also check to see that the column tubes are cen-
tered inside the bore of the table support castings
(Fig. 5). If not, loosen the casting bolts and tighten
the set screws at the front of table support casting to
center the tube. Retighten the bolts and loosen the
set screws.
5. If the height adjustment mechanism feels
rough, check the miter gear (Fig. 14) alignment.
The miter gears can be adjusted on their shafts by
loosening the set screws on the gears. Check and
adjust so that the gear mesh is not too tight or too
loose, and that the gear teeth align with the
opposing gear. Note that the shaft collars located
on the transfer rod should be adjusted to control
the lateral movement of the transfer rod to maintain
accurate miter gear alignment and mesh.
The mesh of the miter gears should be smooth
and even. If not, adjust the gears for good mesh.
Measure the space between the miter gear and the
adjusting screw support that holds the height
adjusting screw in place (Fig. 15). The distance
should be 1/64˝ or less. If there is excessive space,
move the adjusting screw support to the proper
distance above the miter gear and retighten.
Loosen the set screws in the table support castings
(Fig. 3) and test for smooth operation.
6. Next, check the position of the height adjusting
screw. First raise the conveyor table. Then check
the retaining-clip and washer at the top of the
height adjusting screw on the right (inboard) side,
and under the height adjustment handle on the left
(outboard) side of the machine (Fig. 5). On both
sides, the washer and handle should be snug on the
casting and retaining the washer. If there is a space
between the washer and the casting, tighten one set
screw in each of the table support castings. If one
height adjusting screw is loose, remove the miter
gear from the transfer rod on that side. Turn down
the threaded height adjusting screw rod until it is
snug on the washer. Make sure both sides are snug
on top. Reinstall the miter gear and tighten.
Loosen the set screws in the table support castings
and test for smooth operation.
