5. Continue this procedure for all the roll boxings, then insert the new eccentric in the roll
boxing putting a light weight oil on the eccentric as you insert them.
6. Use a light weight oil to apply to the journal of the idler rolls. Then install the number
three right and left roll boxing on the roller journal. The roll gear should be next to the
right roll boxing. Install it back into the folder in reverse order that you removed them.
7. Continue this process with the number five roll, and then four, two, and number one rolls.
AFTER THE ROLLS ARE INSTALLED
1. Set the protractor at five degrees,(the indicator
would be at 95 degrees.) Be sure the #1 and
main drive rolls are together by tightening the
adjustment knob until the washer under the roll
boxing is about 1/16
th below the roll boxing at
all times during the adjustments.
2. Place the protractor on the end of the #1 and the
main drive roll as shown in Figure 1.
3. Refer to the notes as to the location of the
eccentric and start with the witness mark of the eccentric in that position. Rotate the
eccentric until the protractor bubble is five degrees in front of the main drive roll. Repeat
for the other end of the number one roll. Check both ends again to insure both ends are
the same, (five degrees.)
NOTE: Be sure the high point, (see Figure 2 below), of the eccentric is the same
direction on both sides. It is possible to get the same reading with the eccentric 180
degrees off, but the pivot point will be different.

4. To set the end play in the number one roll, insert a ten thousands feeler gauge between
the collar on the roller and the roll boxing. Use a flat blade screw driver between the
other side of the collar and the body of the roller moving the roll toward the gear side of
the roll. Hold a very light pressure and tighten the set screw in the collar. You should be
able to move the feeler gauge in and out with slight drag. Separate the number one roll
and the main roll. Work the number one roll side ways and you should have very little
movement.
5. Take the end play out of the main drive roll without using the feeler gauge. It should not
have end play BUT allow the roll to turn free without a bind. Tighten the number one
roll against the main drive roll until the washer under the roll boxing has no tension but is
still in contact with the roll boxing.
6. Loosen the set screw in the tension adjusting
screw and loosen the tension on the spring on the
right and left roll boxing. Now tighten it until the
tension adjusting screw just begins to put pressure
on the spring, then turn it one and one half turns
on a adjust adjustment screw with course threads
or two turns on a adjustment screw with fine
threads. To test the tension, you can insert a fine
