Servicing the Model 4 and 6 Nameplate Detail Presses
The most common replacement on the nameplate detail press is the ram, part
number 033074, detail 28. This device carries the character dial up and down
while making a mark, so it receives the most wear. We recommend replacing the
depth adjustment screw (part number 033086, detail 39-44) at the same time the
ram is replaced.
The most common adjustments are for tag thickness and table spacing
The following tools will be needed to service the Model 4 and 6:
3/32” long arm hex key
3/16” long arm hex key
5/16” box / open end
wrench
3/8” box / open end wrench
6” adjustable wrench
slotted blade screwdriver
6-inch scale
Note: On machines prior to serial number 45000, the jam nut on the bell crank
screw was 7/16” across the flats, hence the reason for the adjustable wrench in
addition to the box /open end wrenches.

7. Lift the table slide assembly
from the machine base and
remove.
8. Unscrew the depth adjustment screw (39-44) from the ram. The ram can
then be pushed down and off the machine.
Note: Occasionally, the gib (27, located on the left hand side of the dove-tail
section) will drop off the machine when removing the ram.
To re-install the gib, hold the gib in place while installing the new ram. The gib
should be flush with the face of the casting, otherwise it will interfere with the
character dial during operation. There are three set screws (gib screws) with jam
nuts that hold the gib in place. The screws may have to be loosened in order to
install the new ram (28). When the new ram is in place, snug up the screws and
then tighten the jam nuts. Make sure that the ram (28) has free up and down
motion when you pull down on the operating handle (32-33). If the ram does not
travel freely, loosen the gib screws slightly and snug the jam nuts.

Installing the new Ram
1. Using a scale, note the distance between the head of the capstan screw
(30) and the top of the damaged ram before removing the capstan screw.
Keep the distance the
same when replacing the
capstan screw into the
new ram. Also remove
the 3/32” set screw from
the damaged ram and
re-install it into the new
ram until it makes
contact with the capstan
screw – do not tighten
the set screw yet.
2. Slide the new ram from
the bottom up through
the dove-tail section of
the casting, then replace
plunger spring (46) into hole at top of casting and screw the depth
adjustment screw into the ram until the operating handle can be pulled
down no further than the 9 o’clock (horizontal) position.
3. Re-install the table slide assembly (4-21-41) onto the machine base using
the four ¼ - 20 socket head cap screws.
4. Turn the machine upside-down and install the connector link (36) to the
stud on the bell crank (17) and stud on the pawl assembly (11-12-7-38).
5. Replace the character dial and test the machine for spacing and depth of
mark.
Note: There are two (2) studs on the pawl assembly. The connector link
should be placed on the stud opposite the stud that the space button
assembly (2-24) pushes on.

Model 4 & 6 Adjustment Procedures
Adjusting the Model 4 or 6 for Tag Thickness
To determine if the machine requires adjustment, (with the character dial on
machine) pull the operating handle (32-33) down. the operating handle should
not be pulled down past the 9 o’clock (horizontal) position. if it does, adjust the
depth adjustment screw (39-44) clockwise until you can pull down to slightly
above the 9 o’clock (horizontal) position.
It is crucial that when making a mark with your Model 4 or 6, the operating
handle should not be pulled down past the 9 o’clock (horizontal) position.
The head of the depth adjustment screw (39-44) should hit the machine
casting when the operating handle is pulled down to the 9 o’clock
(horizontal) position. This will control the depth of mark and avoid bending
the depth adjustment screw and breaking the ram.
Place a tag to be marked in the Table Gauge Assembly (41-73) [or in your
current tag fixture or nest] and pull down on the operating handle.
Is there a mark? Is the mark too deep or too shallow?
If the mark is too deep….
1. Remove the character dial from the machine. Insert the end of a 3/32” hex key
into any of the holes in the capstan screw (30) and turn the capstan screw
approximately four to five holes clockwise. This will move the ram upward and
away from the piece to be marked.
2. Readjust the depth adjustment screw (39-44) counter clockwise so that when
the operating handle is pulled down it stops slightly above the 9 o’clock
(horizontal) position.
3. Replace the character dial on the ram and pull down on the operating handle
to make a mark on the tag. If the mark is still too shallow, repeat steps 1 & 2. If
mark is acceptable, remove the character dial and tighten the 3/32 set screw
(located near the top of the ram). Replace the character dial on the ram. Your
depth of character is now completed.

If the mark is too shallow….
1. Remove the character dial from the machine. Insert the end of a 3/32” hex key
into any of the holes in the capstan screw (30), and turn the capstan screw four
or five holes counter clock-wise. This will move the ram downward and closer to
the piece to be marked.
2. Readjust the depth adjustment screw (39-44) clockwise so that when the
operating handle is pulled down it stops slightly above the 9 o’clock (horizontal)
position.
3. Replace the character dial on the ram and pull down on the operating handle
to make a mark on the tag. If the mark is still too shallow, repeat steps 1 & 2. If
mark is acceptable, remove the character dial and tighten the 3/32 set screw
(located near the top of the ram). Replace the character dial on the ram. Your
depth of character is now completed.
When the depth of mark is satisfactory for your application, you may experience
the table skipping when you make a mark. This is common when a depth of
mark adjustment is made by changing the capstan screw position.
Adjusting the Table Spacing on the Model 4 and 6
1. Remove the character dial from machine.
2. Push the table (5) all the way to the right.
3. Remove the stop screw from the table slide (located at the upper left hand
corner of table slide assembly 4-21-41).
4. While holding the table with your left hand, push in and hold the space button
(2-24), and slide the table off the machine to the left.
5. Turn depth adjustment screw (39-44) counter clockwise approximately five
turns, then pull operating handle (32-33) down until the shaft of the operating
handle rests on the table slide assembly - leave the handle in this position
throughout the following procedures.

6. Verify the adjustment of the pawl assembly in relation to the escapement
wheel assembly.
The escapement wheel assembly (13-14) is located in the center of the table
slide assembly.
The pawl assembly (11-12-7-38) is located in between the teeth of the
escapement wheel assembly (13-14).
Move the handle to the 9
O’clock position.
If the machine is
adjusted properly, the
top of the pawl should be
flush with the top of the
flat gear on the
escapement wheel
assembly. You should be
able to run a fingernail
across the flat starburst
gear and across the pawl
assembly.
To adjust the pawl assembly height, continue with the following steps:
7. Turn machine upside down and locate the nut and screw on the bell crank
(17).
8. Loosen the nut on the bell crank.
9. Turn the screw on the bell crank clockwise to adjust the pawl assembly
downward to achieve flushness with the escapement wheel assembly or counter
clockwise to raise pawl assembly until flush with escapement wheel assembly
10. Tighten the nut on the bell crank once the adjustment is complete. Turn
machine right side up.

11. Raise operating handle and turn the depth adjustment screw clockwise until
the operating handle can be pulled down no further than slightly above the 9
o’clock (horizontal) position.
12. Slide the table back onto the machine and replace the stop screw on the
table slide assembly.
13. Install the character dial on the machine.
Important Note!! - It is crucial that when making a mark with your Model 4
or 6, the operating handle should not be pulled down past the 9 o’clock
(horizontal) position. The head of the depth adjustment screw (39-44)
should hit the machine casting when the operating handle is pulled down
to the 9 o’clock (horizontal) position. This will control the depth of mark
and avoid bending the depth adjustment screw and breaking the ram.
