Inspecting, replacing, and installing the Card Feed Roller (D850415) (continued)
Step Procedure
8 Slide the old Shaft out.
Install the new Card Feed Roller (D850415). (Note: Ensure that the flat on the
Shaft extends through the front Sideplate.)
9 Re-install the Bushings.
10 Re-install the Snap Ring and the E-Clip.
11 Install a new Pulley (D850190) onto the Feed Roller Shaft.
a. Turn the Cleaning Roller and the Feed Roller so that the flats face toward the
Output Hopper. (Note: The flats must be in the same position.)
b. Loop the Belt over the Cleaning Roller Pulley and over the new Pulley,
aligning the flat of the Pulley to the flat of the Shaft.
c. On the Feed Roller, place the flat of the Pulley against the flat of the Shaft.
d. Press the Pulley onto the Shaft. (Note: Use careful force here because you
are working against the Belt.)
Caution: It is important not to roll the Pulley into the flat of the Shaft. If
the shaft is rolled into the flat, the flat can shear out the crush ribs inside the
Pulley. Removing these ribs allows for free play in the Pulley and causes a poor
fit.
e. Slide the Cleaning Roller Pulley back into position. Slide the Feed Roller
Pulley to the point where it is in line with the Cleaning Roller Pulley. (Note:
The Pulleys need to be straight to prevent wear on the Belt.)
12 Re-install the E-Clip on the end of the Cleaning Roller.
13 Re-install the Hopper.
