1. Height-of-cut bracket
2. Adjust the 1.5 mm (0.06 inch) shims and/or 0.7
mm (0.03 inch) shim between the cutting unit
frame and bracket to achieve the desired height
of cut (Figure 72).
3. Install the height-of-cut bracket to the cutting
unit frame with the remaining shims assembled
below the height-of-cut bracket
4. Secure the socket-head bolt and spacer and
flange nut.
Note:
The socket-head bolt and spacer are
held together with thread-locking compound to
prevent the spacer from falling inside the cutting
unit frame.
5. Verify the 12 o'clock position setting and adjust
if needed.
6. Determine if you need to adjust only 1 or both
(right and left side) height-of-cut brackets.
Note:
If the 3 o'clock or 9 o'clock side is 1.6 to
6.0 mm (0.06 to 0.24 inch) higher than the new
front height, then you do not need to adjust for
that side. Adjust the other side to within ± 2.2
mm (0.09 inch) of the correct side.
7. Adjust the right and/or left height-of-cut brackets
by repeating steps
8. Secure the carriage bolts and flange nuts.
9. Verify the 12, 3, and 9 o'clock heights.

Servicing the Front Roller

Inspect the front roller for wear, excess wobble, or
binding. Service or replace the roller or components if
any of these conditions exist.

2. Mounting bolt
2. Insert a punch through the end of the roller
housing and drive the opposite bearing out
by alternating taps to the opposite side of
inner-bearing race.
Note:
There should be a 1.5 mm (0.06 inch) lip
of inner race exposed.
3. Push the second bearing out in the press.
4. Inspect the roller housing, bearings, and bearing
spacer for damage
Note:
Replace damaged components and
assemble the front roller.
Installing the Front Roller
1. Pressing on the outer race only or equally on the
inner and outer race, press the first bearing into
the roller housing
Note:
Press on the outer race only or equally
on the inner and outer race.
2. Insert the spacer
3. Pressing on outer race only or equally on the
inner and outer race, press the second bearing
into the roller housing until it contacts the spacer
(Figure 73).
4. Install the roller assembly into the cutting unit
frame.
Important:
with a gap larger than 1.5 mm (0.06 inch)
creates a side load on the bearing and can
lead to premature bearing failure.
5. Verify that there is no more than a 1.5 mm (0.06
inch) gap between the roller assembly and the
roller-mount brackets of the cutting unit frame.
