Remove screws (2) from upper portion of mounting brackets (13) and move yoke shaft bushings (10) clear
of mounting bracket openings.
Lift yoke shaft (8) out of mounting bracket openings.
When removing color press, secure yoke shaft bushings (10) to turnbuckles (11) to prevent cylinder
Remove the color press assembly, leaving mounting brackets in position on the duplicating machine.
If the mounting brackets are undamaged, they may be retained for use with new color pres.
If necessary, remove mounting brackets (13) by removing attaching screws (3) and releasing setscrews (4
Adjust setscrews (4, fig. 4-8) so as to clear the opening in the top portion of each mounting bracket (13).
Position mounting brackets on duplicating machine and install attaching screws (3).
Tighten setscrews (5) to provide for a snug fit against duplicating machine frame.
Tighten setscrew (4) on each mounting bracket.
Remove the ink and water fountain control knobs. (See fig. 4-6.)
Remove the knobs from the ink and water feed control shafts. (See fig. 4-6 and 4-7.)
Remove the two screws which attach the left and right guards and remove the guards.
Remove the ink and water oscillators and the number 2 form from the color press assembly in accordance
with commercial manual instructions.
Loosen the three main tie rod (16, fig. 4-8) attaching and adjusting nuts(6).
Position the color press assembly on the mounting brackets with the bolts on holddown bar (7) protruding
through the rear holes of the mounting brackets (13).
Position yoke shaft (8) through slotted holes in mounting brackets and insert screw (2).
Install holddown bar attachment nuts (1) and secure main tie rod attaching and adjusting nuts (6).
Place a level on the duplicator blanket cylinder and then on the color press plate cylinder. The level
indications should be identical. If they are not, adjust color press plate cylinder as follows:
Loosen holddown bar attachment nuts (1).
Adjust leveling screws (9) until level indications of duplicator blanket cylinder and color press plate
cylinder are identical.
Tighten holddown bar attachment nuts (1).
Loosen the main tie rod attaching and adjusting nuts (6). The center bolt acts as a pivot point in relation to
the turnbuckles (11). The two outside bolts pass through elongated holes in the holddown bar (7), to permit movement
around the pivot point, when adjusting the turnbuckles (11).
Position yoke shaft bushings (10) into mounting brackets, ensuring that slot in bushing is uppermost and is
visible in the bracket openings.
Secure screws (2) in mounting brackets at the same time moving the yoke shaft pressure handle (15)
backwards and forwards until a tightening in the handle is felt.
With pressure applied to the pressure
handle, adjust turnbuckles (11) until the color press plate and duplicator blanket cylinders are approximately parallel.
This is achieved by sighting between the two cylinders and adjusting each until any light visible between the two can no
longer be seen.
Check that slots in yoke shaft bushings are still uppermost and that slight pressure can still be felt in the
yoke shaft pressure handle (15).
Install the ink and water oscillators and the number 2 form in accordance with commercial manual
