PRESSURE BAR GEARBOX (con’t)
The pressure bar gearbox is adjustment free.
1. Remove the rear motor cover and the outside
frame guard (see Figures 3-288 thru 3-290).
2. Loosen the four gearbox mounting screws.
Once the gearbox is able to slide in the
adjustment slots, lift the motor up to remove
the belt (Figure 3-292).
3. Remove the two set screws from the taper-lock
bushing on the gearbox pulley. Using one of
these set screws, thread into the middle hole
(identified in Figure 3-293). This will remove
the bushing from the pulley, thus removing the
pulley and bushing from the gearbox. Note:
The gearbox shaft and the bushing are coupled
to spin together with a square key. This will
also be free once the bushing is removed.
4. Completely remove the gearbox mounting
screws.
5. Unplug the pressure bar motor, allowing the
gearbox and motor to be removed from the
machine.
6. Once free of the machine, remove the motor
from the gearbox, and replace onto the new
gearbox. Note: the motor shaft may need to be
turned to get the pinion gear to fully engage the
gearbox. Also be certain the motor is oriented
in the correct position, such that the plug will be
to the inside of the machine when installed.
