Brush Replacement (figures 15-15a-15b-15c)
Important: Replace the brushes when the
diameter reaches
15".
1.
Place the tractor mounted with the broom
on a clean, flat and level surface. Put the
transmission in neutral, apply the parking
brake, raise the broom with the lifting
mechanism, turn off the engine and wait for
the brush to stop turning completely.
2. Figure 15:
Remove the chain idler (item 1)
from the broom housing (item 2) by
removing the 3/8"NC nylon insert locknut
(item 3), the 3/8" lockwasher (item 4) and
the 3/8" flat washer (item 5).
3. Figure 15a:
Place the two engagement
levers (item 4) in the "A" position and,
using the tractor's hydraulic lever, lower the
broom so the brush touches the ground.
4. Figure 15a:
Remove the 1/2"NC x 1 1/4"lg
hex. bolts (item 1) and the 1/2"NC serrated
flange nuts (item 2) from the brush support
right side bearing (item 3).
5. Figure 15a:
Place the engagement levers
(item 4) to position "B" to release the
brushes from the broom housing (item 5). If
the brushes aren't released sufficiently
from the broom, raise the broom as
needed with the subframe lift mechanism.
6. Figure 15b:
Remove the three 5/16"NC x
2 1/2" lg hex bolts (item 2), the three 5/16"
lockwashers (item 3) and the retaining
plate (item 1) from the brush support
(item 5). Take off all the brushes (item 4)
from the brush support (item 5).
IMPORTANT: If you decide to install half
steel/half polypropylene brushes, you must
start and finish with a polypropylene brush.
7. Figure 13b:
Install each brush (item 4) in
the opposite direction of the one next to it.
The two pins on each brush (item 4a) that
secure the brushes to the support must be
alternated 120° (1/3 of a turn) to obtain a
balanced distribution on each of the
support's three square tubes (item 5a)
Insert the brushes in that order until the
last one exceeds the end of the brush
support. Then remove the last brush and
measure distance
A
(figure 13c).
If distance
A
is between:
0" and 1/4":
do not add a brush,
1/4" and 7/8":
add one brush in the
same direction as the last one,
7/8" and plus":
add one brush in the
opposite direction of the last one.
8. Figure 15b:
Secure the brushes with the
retaining plate (item 1), the three. 5/16" NC
x 2 1/2" lg hex bolts (item 2) and the three
5/16" lockwashers (item 3).
9. Figure 15a:
Lower the broom housing
(item 5) by moving the engagement levers
(item 4) in the "A." position. If the housing
is too high to align the holes of bearing
(item 3) with those of the housing (item 5) ,
lower the housing as needed with the
subframe lift mechanism.
10. Figure 15a:
Attach the
brush support
bearing (item 3) with the two 1/2"NC x 1
1/4"lg hex bolts (item 1) and 1/2"NC
serrated flange bolts (item 2).
11. Figure 15:
Reinstall the chain idler (item 1)
with the 3/8"NC nylon insert locknut
(item 3), 3/8" lockwasher (item 4) and the
3/8" flat washer (item 5). Refer to page 21
for the proper chain adjustment.
