REPLACING OR ADDING ROLLER WHEELS
Although the packer wheels are manufactured from high grade ductile iron, wear or breakage may
require that some wheels be periodically replaced. Follow these steps when replacing wheels.
1. Attach a tractor to the pulverizer, put the tractor
transmission into PARK, and lock the brakes on
the tractor.
Hydraulically raise the pulverizer. Slide all the
wheels toward one end of the drum.
Lower the pulverizer so that the
packer wheels rest on blocks
approximately two inches off the
ground (see figure 8).
Continue to lower the machine
till the outside of the roller drum
contacts the bottom ring of the
packer wheels.
2. Remove the pillow block bearing and the
bearing support from the end of the drum to
which youwill be adding wheels. The pillow
block bearing is secured to the drum shaft by
means of an eccentric locking collar.
Loosen the set screws which tighten the collar
to the shaft. Then with a punch, rotate the collar
in the direction opposite which the shaft turns in
normal operation.
Next remove the nuts from the bolts which mount
the bearing supports to the frame and slide the
bearing and the support off the shaft.
Remove the three 5/8" lock nuts which attach the
retainer plate to the drum and remove the plate.
