PREPARATION TO INSTALL NEW ROLLERS Continued….
5.
Check the new main drive roller with the old one to insure the correct end to put on the
roll gear. Some main drive rolls have a spacer between the roll gear and the main drive
roll sleeve. Check the old main drive roll to see if your folder needs the spacer. Install the
new drive roll gear, and spacer if needed, on the main drive roller. Install the collar on
the opposite journal. If you are working on a rollaway section of the 200 or 700 series,
install the cross carrier drive gear instead of the collar. The gear hub should be away
from the body of the roller. Remove the main drive roll sleeve from the frame and slide
the main drive roller in the opening in the frame. Be sure the roll gear is toward the non-
operator (right) side. The rollaway sections have the roll gears on the left side of the unit.
On the sixteen-page unit or second right angle, the third roller has a roll gear on both
sides. This is to change the drive so the stacker drive doesn’t interfere with the
roller
drive. Any time you have a gear on the roller and a collar above or below it, always use a
smaller diameter collar so it doesn’t interfere with the gear. Replace the left main drive
roll sleeve then
tighten the three bolts that fasten the main drive roll sleeve. The main
drive roller should turn free.
PREPARING ROLLER BOXING FOR INSTALLATION.
1. Check each roll boxing before pressing out the old bushing to
insure you can drill the oil hole in the bushing AFTER the new
bushing is pressed in. If not, measure the location of the hole in
the old bushing. Drill a slightly larger hole in the same
measurement in the new bushing before it is pressed in the
boxing. Press out the old oilite bushing. Lines up the hole drilled
in the new bushing with the oil hole in the boxing and press the
bushing in the boxing leaving .015 thousands past the surface of the boxing that faces
the body of the roller. You can usually look on the side of the roll boxing for the witness
mark for the eccentric to identify the side toward the roller body. If this is not done, the
folder may begin squealing after it runs for a couple of hours and you will have to do the
work over. If the collar or roll gear rubs against the metal of the roll boxing, you may get
this noise. After pressing in the bushings in all the roll boxings, place the roll boxings in
pairs back-to-back and insert a shaft 5/8-inch in diameter through the eccentric holes
and ream them as a pair .002 thousands larger than the roll journal (shaft).
2.
Continue this procedure for all the roll boxing. Put lightweight oil on the new eccentric
and insert it into the roll boxing. Add a light coat of oil in the roll boxing. Inspect the roll
boxing, the collar on the roller, and any other surface where two parts make contact are
free from any burrs or ruff surfaces to insure free movement. Install the boxing on the
roller journal; make sure the roll gear is on the correct side. Move the collars toward the
body of the roller and snug the setscrew on the flat of the roller journal. This is so you
know where the flat is later when you set the endplay and you tighten the setscrews.
Now you are ready to begin installing the rollers back into the folder. Install the rollers in
the reverse order that you removed them.
