Time Recorders
Service Manual and Parts Reference
This manual references the parts and service for Model 125 & 150
Recorders. Reference Service Manual 06-0115-000 Rev. “D” for clocks that
have either metal front cases or back cases.
Lubricant: Unless otherwise noted, use NLGI#0 grease for lubrication.
I. Motor and Drive Assembly
Lubricate the following areas twice a year:
1) The area of contact on Minute Drive Lever and the stud in the Minute
Drive Cam.
2) Where the Minute Drive Lever contacts the Minute Shaft and Minute
Shaft Bearing.
3) The pivotal points of the Feed and Detent Pawls.
The time recorders are driven by a 115volt AC, 60 cycle, 1rpm motor (240 volt
AC, 50 cycles units are also available by request). The motor rotates the minute
drive cam one revolution each minute. Accuracy of the recorder is based on the
line frequency provided all the drive train parts are properly installed, adjusted
and lubricated. These parts should be checked for wear and replaced as
necessary.
The motor rotates the Minute Drive Cam that turns and pushes down on the
Minute Drive Lever allowing it to advance one minute. As the lever is
compressed by the Minute Drive Cam the Minute Feed Pawls will advance the
Minute Drive Ratchet one tooth allowing it to change the Minute Type Wheel with
every revolution of the Minute Drive Cam.
The Minute Drive Gear is secured to the Minute Drive Shaft by two set screws.
The drive gear is adjusted to the gears of the Minute Type Wheel. When setting
the drive gear to the Minute Type Wheel you must turn the Minute Wheel counter
clockwise with the Drive Gear until it stops. At this point tighten the set screws in
the Drive Gear. Note: If the Drive Gear is set too close against the Minute Type
Wheel it could cause the Minute Wheel to bind and not turn properly.
II. Typehead Assembly
See Typehead Assembly Drawing

2
III. Wheel Alignment
To set the 24-Tooth Hour Ratchet to the Hour Wheel Shaft, manually advance
the ratchet by actuating the Hour Follower Lever until the Day-Date Ratchet
advances, then carefully rotate the Hour Wheel to "12" midnight or "0" Hour to
the bottom center printing position and in line with the "00" minutes. Tighten set
screws and check for binds or any misalignment. The Day-Date Wheel can now
be set to the Hour Wheel. Align the Day-Date Wheel with the Hour and Minute
Wheels and tighten the ratchet set screws making sure that the Day-Date
Ratchet and the Hour Ratchet are not touching which could cause binding.
Grease the Hour Drop-Off Cam on the Minute Wheel (see Item 2, Pg 19) and the
Day-Date Cam (see Item 35, Pg 19). Also apply a thin coat of grease to the 24,
28, or 31-Tooth Ratchets (see Item 36, Pg 19). This should be done twice per
year.
When it is necessary to remove the Type Wheels from the recorder, always clean
and lightly oil the bearing surfaces upon re-assembly.
It will be necessary to periodically clean the Type Wheel printing surfaces. DO
NOT USE A SOLVENT CLEANER as most solvents could eventually "gum-up"
the Type Wheel Assembly. Brush the Type Wheels with a soft bristle brush to
remove any buildup.
If the recorder is a left print model (for left side of card registrations) an
Intermediate Gear is fixed over the Minute Drive Wheel and should be carefully
engaged so that it only engages the Minute Drive Wheel and not the Minute
Drive Gear.
A. Removing the Typehead Assembly
1. Remove Hour and Minute Hands. Notice that a lock washer is located behind
the Minute Hand. The Hour Hand is attached to the Hour Hand Gear by
means of a friction fit and can be removed with a gentle pulling and twisting
motion.
a. Remove clock Dial Plate (1 Screw in each corner).
b. Remove Ribbon
c. Remove (4) screws attaching the Front Mounting Plate Assembly.
d. Remove the Front Mounting Plate Assembly.
2. Remove four screws (2 on each side) to separate the Assembly Frame from
Back Case. Lay Assembly Frame on bench face down and remove the four
screws holding the Typehead in the Assembly Frame. One screw is under the
Hammer Trip on the Model 125. Pulling down the Hammer will reveal this
screw. This will separate the Typehead from Assembly Frame.

3
B. Dismantling Typehead Assembly
Due to the complexity of the Typehead we recommend replacing the
Typehead Assembly instead of attempting repair in the field.
Loosen the two set screws in the Day-Date and Hour Ratchets. Remove the E-
Clip from the Detent Stud and remove the ratchets. Disconnect the Detent Spring
from Detent Pawl and remove Detent Pawl. Lift Day-Date Follower Lever off the
Detent Stud and disconnect the two springs from the Typehead Rear Plate.
Remove the Stud Collar. Unhook the Detent Spring from Hour Detent Pawl and
remove the Detent Pawl. Unhook two springs from the Hour Follower Lever and
remove it. Loosen and remove the four Typehead Spacers. The Type Wheels
can now be removed. Before the Type Wheels are separated, remove the set
screw burrs on the Hour Wheel Shaft (Brass) and Day-Date Wheel Shaft (Steel)
by lightly filing and sanding them smooth. Now the Type Wheels can be
separated. There are three different Type Wheels (Day-Date, Hour and Minutes).
The Day-Date Wheel has a solid ¼” steel shaft. The Hour Wheel has a brass
shaft with a 1/4" hole in the center. The Minute, Tenths or Hundredths Wheels
have a molded gear and cam on one side. The Month, Year and Symbol Wheel
Bracket is mounted to the Front Plate with screws.
C. Reassembling Typehead
Due to the complexity of the Typehead we recommend replacing the
Typehead Assembly instead of attempting repair in the field.
Assemble the Day-Date, Hour and Minute wheels. Put one drop of oil on the tip
of the Day-Date Wheel shaft. Place three .010” Shims on the shaft. Lightly
grease the brass Hour Wheel shaft and assemble it to the Day-Date Wheel shaft.
Place a .005” Shim on the Hour Wheel shaft then assemble the Minute Wheel to
the Hour Wheel shaft and lightly grease the Minute Cam. Insert the tip of the
shaft of this wheel assembly into the hole of the Rear Plate. Install the Typehead
Front Plate and secure with four Short Typehead Spacers. All three Type Wheels
should spin freely. If there is any drag check for burrs. Flip the Typehead over
and assemble the Hour Follower to the Lower Rear Plate Stud. Next assemble
the Collar Stud and attach the Hour Spring from the Hour Lever to the Rear Plate
hole. Now attach the Detent Spring from the Hour Pawl to the next Rear Plate
hole.
Assemble the 24-Tooth Hour Ratchet to the brass Hour Wheel shaft. Attach the
Hour Pawl to the Upper Rear Plate stud. Attach the Hour Pawl Spring to the
black Rear Plate stud and Hour Pawl. Insert the Day-Date Follower onto the
Lower Rear Plate shaft. Use a .005” or .010 shim as necessary on the Upper
Rear Plate Stud (to remove excess play) and secure with an E-Clip. Add the
Day-Date Spring to the Day-Date Follower and connect it to the third Rear Plate
hole. Add the Day-Date Detent Spring to the Day-Date Pawl and connect it to the
last Rear Plate hole. Add the Hour Pawl to the Upper Rear Plate Stud. Attach a

4
spring to the black Rear Plate Stud. Secure the Hour Pawl to the Stud with an E-
Clip.
The Hour Cam is a white plastic cam attached to the 24-Tooth Hour Ratchet. The
24-Tooth Hour Ratchet has to be in position so that the Hour Follower Lever will
operate at 12:00 MIDNIGHT.
Rotate the Minute Wheel counter clockwise until it stops. The Minute Wheel will
stop when Hour Follower Lever bottoms on the Minute Cam. This will also
position the Minute Wheel to be in a "00" printing position. Manually operate the
Hour Follower Lever so the Hour Feed Pawl drops into the next tooth of the
Ratchet. Release the Hour Follower Lever and the Hour Ratchet will advance
one tooth. The Hour Detent Pawl should drop into the ratchet and have about
.002" clearance. The Detent Pawl must drop into the ratchet. If the Minute Wheel
is in the correct position and there still isn’t any clearance, adjust the Ratchet
Pawl Stop Screw. Loosen the Hex Nut and unscrew the Ratchet Pawl Stop
Screw about 1/2 turn. Tighten the Hex Nut. Too little clearance will cause binding
of Hour Follower Lever resulting in the Typehead losing hours.
Too much clearance will cause the hours to be out of alignment. Do not tighten
both set screws -- this is a temporary adjustment.
The Detent Pawl and Day-Date Follower Lever should have as little side
clearance as possible yet be free of binds. There should be 1/16" clearance
between the tab on the Day-Date Follower Lever and Hour Ratchet. Too little
clearance will bind the Hour Ratchet and result in losing hours. Adjust for approx
.002" clearance between the Detent Pawl and Ratchet. The Detent Pawl should
be free on stud. If tight or binding you may have to remove the shim.
When actuating the Hour Lever by hand it should operate from its own spring
tension all the way around the Hour Ratchet. If binding occurs check for
clearance between the ratchets. Also check for burrs on the Detent Pawl,
ratchets or Type Wheels, and clearance between the Day-Date Detent Pawl and
Day-Date Ratchet. If this does not correct the problem it may be necessary to
replace the springs.
There is a 1/8" hole in all Type Wheels that should be in alignment. When aligned
the Minute Wheel should be at "00" position, the Hour Wheel at 12:00 MIDNIGHT
position and the Day-Date Wheel should be at “Monday” or “1” depending on if it
is a Day or Date Wheel. Hold the Type Wheels in position and use an Allen
wrench to tighten the set screws in the Hour and Date Ratchets.
If the Typehead has a Month Wheel install it and the Month Bracket. Leave the
four Month Bracket Screws loose and align the wheel with the rest of the Type
Wheels using a straight edge. Holding the Hour and Detent Pawl out of the way
install the 24-Tooth Hour Ratchet. Install the Day-Date Follower Lever by
connecting springs to Typehead Rear Plate. Install Shim Washer on stud and
Day-Date Detent Pawl. Secure with an E- Clip. Connect the Detent Spring. Press
firmly on the straight edge against the Type Wheels and tighten all four Screws in
the Month Bracket.

5
D. Installing Typehead Assembly
Install the Typehead in the Assembly Frame and tighten all four screws. Install
the Front Plate Assembly -- be sure the set screws in Drive Gear are sitting at
the “12:00” and “3:00” position(s). With the set screws in this position you can
access both set screws to adjust the Minute Wheel. Rotate the Minute Wheel
counter clockwise until it stops. This is the "00" minutes position. While holding
the Minute Wheel in this position, install the Front Mounting Plate Assembly.
Tighten the four mounting screws in the Front Mounting Plate Assembly. After
the Plate has been installed insert the assembly into the Back Case and connect
the motor wires. Install the print ribbon with the hex hole in Ribbon Spools to the
rear of clock and round hole to the front. Loosen both set screws in the Minute
Drive Gear and rotate the gear counter clockwise until it stops. This stop is the
Hour Cam backing up to Hour Follower Lever. This will position the
"00" Minute to print on the card. Hold a slight counter clockwise tension on Drive
Gear and tighten both set screws in Drive Gear. Make sure the molded gear on
the Minute Wheel and Minute Drive Gear are fully engaged. Also be sure the
Drive Gear has minimal contact with the Minute Wheel -- this would cause
binding in the Minute Wheel and Drive Assembly. Print a sample registration on a
time card. Always align the other Type Wheels with the Minute Wheel. The
Minute Wheel will always be the reference point for aligning other Type Wheels.
Now the Minute Wheel is adjusted and tightened. Make another print registration
and compare the printed hour to the printed minute. If the hour prints high or low
it can be adjusted in the following manner: Use the Hour Follower Lever to
advance the Hour Ratchet around until the set screw on Hour Ratchet comes into
view on the left side of clock. Loosen the set screws in the Hour Ratchet and
rotate the Hour Wheel up or down to correct printing. Tighten the set screws and
make another print registration. Continue this adjustment until the hour print
aligns with the minute print. Tighten both set screws in Hour Ratchet. Align the
Day-Date Wheel in the same manner as Hour Wheel. The Day-Date Follower
Lever is the yellow zinc plated lever.
Month Adjustment: Year, Month and Symbol Wheels must be aligned two ways:
(1) for dark or light printing, or (2) aligned with other Type Wheels.
1. Dark or light printing is corrected by moving the Year-Month Bracket up or
down. A simple way to do this is to loosen the four screws in the Bracket
and raise or lower bracket as needed. Tighten the four screws. Make a
sample print – if print is light, readjust Year-Month Bracket. Continue to
adjust the Year-Month Bracket until print output is optimized.
2. The Month Latch has an elongated mounting hole. Loosen the Month
Latch Mounting Screw and slide the Month Latch to the left or right to
adjust the alignment. Sometimes moving the Month Latch will not align the
month printing. In that case, the Year-Month Bracket must be moved.
Adjust the Year-Month Bracket to the left or right.
Repeat steps 1 & 2 until the Year-Month Bracket is properly aligned.

6
IV. Hammer Installation and Trim
Sometimes it is necessary to install a new Hammer when changing from three
wheels to four wheels or when installing a Year or Symbol Wheel. The Hammer
can be installed in the following manner: Remove Ribbon and loosen screws in
Card Stop, and move Card Stop to the rear of clock. Remove the two screws
from Card Table and remove Card Table. Remove Hex Nut from Hammer Trip
Stud. Now the Hammer Assembly can be removed. After installing the new
Hammer Assembly you may need to trim the Rubber Platen per the illustration
below to avoid hitting the card stop and overprint:
Carefully trim shaded area of rubber
platen with An X-Acto knife to prevent
overprint.
Grease the outside of the Hammer Trip Sleeve before installing. Install Hammer
Assembly in clock and tighten nut on Hammer Trip Stud. Install Hammer and
Card Table, adjust Card Stop, and install Ribbon. Take a sample print on the
time card. If print quality is not adequate the Platen may need to be trimmed
around the minutes to remove “shadow print”.
V. Model 150 Printing
When a time card is inserted in the clock, the card will push the Card Finger and
close the Microswitch. The Print Solenoid will energize and pull up both the
Center Bar and the Print Hammer. The Contact Lever simultaneously releases
the Microswitch Blade, opening the Microswitch and allowing the Center Bar to
drop down so that the Ribbon Feed Finger will drive the Ribbon Ratchet. Notice
that the Card Stop is recessed where the Card Finger travels. The Card Stop can
be moved in or out to adjust the printing depth on the card. After adjusting the
Card Stop the Card Finger will need to be readjusted. Left print recorders with
more than three Type Wheels do not have this bar.
VI. Preventive Maintenance Procedures
1. Remove the Front Case and the Ribbon.
2. Dust out the machine with a dusting brush or with compressed air if
available.
3. Remove any grease build-up on the cams and ratchets by using a rag on
the end of a screwdriver blade.
4. Remove any ink build-up on the inside of the Card Table where the
Ribbon slides back and forth using a dry rag.
5. Make sure the Toggle Plate pivots easily and the Shoulder Screw is
snug.
6. Put a drop of oil in the oil access hole found on top of the hubs
supporting the left and right Ribbon Shafts.

7
7. Grease the pivot point of the Trip Latch.
8. Grease each of the three studs that support the Center Bar.
9. The Center Bar should freely return upward after a registration is made.
If there is binding, check and remove grime and deposit buildup and re-
lubricate.
10. Make sure all four set screws in the Typehead Assembly, the two set
screws in both Ribbon Reverse Ratchets and the two set screws in the
Main Drive Gear are tight.
11. Make sure all four Assembly Frame screws, the four Month Bracket
screws and the two Microswitch screws are tight.
12. Check for excessive wear where the Minute Feed Pawl drives the Minute
Drive Ratchet. Replace the ratchet and pawl, if worn.
13. Look directly down behind the Dial to see if any of the parts mounted on
the Front Mounting Plate are touching the back of the Dial. If so, form the
Dial out enough so that nothing touches it.
14. Install a new Ribbon.
15. Make sure the recorder is printing proper Day-Date and Time.
16. Put the Front Case back on the machine.
VII. Service Tips
A. Losing time (minutes).
1. Check 1 RPM motor with Second Hand on watch - Minute Drive Lever
should operate at the same second for 4 or 5 minutes.
2. Check travel on Minute Feed Pawl -- should be 1-1/4 teeth -- check for
loose Minute Feed Pawl Stop. More than 1-1/4 teeth travel will allow
Minute Feed Pawl to jump a tooth in Minute Ratchet.
3. Binding Minute Wheel against Drive Gear.
4. Binding Hour Reduction Gears.
5. Minute Cam loose on motor -- set screw loose in Drive Gear.
6. Worn Minute Drive Cam Stud or worn Minute Drive Lever. Replace
Front Plate Assembly.
7. Check parts for lubrication.
8. Ask User if they have experienced any power failures recently.
B. Losing time (hours).
1. Hour Ratchet set screws loose.
2. Hour Ratchet binding on Typehead Rear Plate.
3. Hour Detent Pawl binding -- not enough clearance.
C. Gaining time (minutes).
1. Minute Feed Pawl backing up two (2) teeth.
2. Minute Feed Pawl Stop Loose.
D. Gaining Time (hours) - Type Wheels one or more hours ahead of clock
face.
1. The Hour Ratchet Pawl Stop screw loose -- causing hours to advance
two hours at a time.

8
2. Set Screws in Hour Ratchet loose, causing Hour Wheel to spin freely
and appear to gain time.
3. Binding Hour Detent Pawl.
E. Day or Date not changing.
1. Set screws in Day-Date Ratchet loose, causing Day-Date Wheel to
spin freely.
2. Too much side-play in Day-Date Follower Lever.
3. Day-Date Detent Pawl binding -- not enough clearance.
4. Day-Date Pawl Stop screw too tight, not allowing pawl to advance.
5. Clock may be set 12 Hours off, Day-Date would appear to advance at
noon instead of midnight.
F. Light or weak print.
1. Ribbon worn out or not reversing.
G. Ribbon not reversing.
1. Too much tension on Ribbon Tension Spring.
2. Toggle Plate screw loose
3. Toggle Plate binding.
4. Finger Spring broken or disconnected.
5. Ribbon Drive Gear loose on shaft.
H. Center Bar Binding/Malfunction.
1. Check Guide Stud washers & E-clips.
2. Check Print Solenoid Pin and E-Clip.
3. Clock mounting surface not flat.
4. Center Bar Return Spring broken.
5. Sliding areas dry or gummy.
I. Glass Installation (Eye protection should be worn when installing /
removing glass)
1. Remove cover and place face down on table.
2. Carefully remove any broken glass
3. Remove round push-on clips that retain the glass. Some of the plastic
posts to which the clips are attached may have to be cut off with pliers
to remove the clips. Extra plastic posts are molded into the cover in
case the original ones are damaged.
4. Lay replacement glass into cover and push on new clips to retain the
glass. A nut driver works well for installing clips.

VIII. Electrical
Caution: These clocks use high voltage AC. Only qualified service
personnel should attempt repairs.
A. Model 125 (120v/240v)
AC power is directly wired to the 4-watt motor. If clock is not keeping time, check
for the following conditions:
•No power at outlet – reset circuit breaker.
•Faulty Motor – replace motor.
•Faulty Power Cord or Power Cord to Motor wire connector – replace.
B. Model 125 (6-volt & 12-volt) Battery Power
•Make sure batteries are fresh and properly installed.
•Make sure battery voltage is present at the blue (-) and yellow (+) wires at
the circuit board
•Make sure that 5vDC is present on the orange and gray wires at the circuit
board once every minute for about 3 seconds. If yes and motor does not
start turning - replace motor. If no - replace printed circuit board.
•If motor does not turn full cycle to advance time check for defective
Microswitch and replace.
C. Model 125 Rechargeable Battery Power
•Make sure batteries are fully charged and properly installed
•If batteries are not charging:
1) Check power at the wall and for AC voltage on purple wires, if none
check connections from power cord.
2) If AC present, batteries may need to be replaced or printed circuit
board may be defective – replace.
•Make sure battery voltage is present at the blue (-) and yellow (+) wires at
the circuit board.
•Make sure that 5vDC is present on the orange and gray wires at the circuit
board once every minute for about 3 seconds. If yes and motor does not
start turning - replace motor. If no - replace printed circuit board.
•If motor does not turn full cycle to advance time check for defective
Microswitch and replace.

10
D. Model 150 (120v/240v)
AC power is directly wired to the 3-watt motor. If clock is not keeping time, check
for the following conditions:
•No power at outlet – reset circuit breaker.
•Faulty Motor – replace motor.
•Faulty Power Cord or Power Cord to Motor wire connector – replace.
AC power is also wired directly to the Microswitch and AC Rectifier. Power routes
through the
Microswitch to an AC Rectifier and then to the Print Solenoid. If the automatic
punch is not functioning, check for the following conditions:
•No power at outlet – reset circuit breaker.
•Faulty Power Cord or wiring to the AC Rectifier, Microswitch or Print
Solenoid.
•Check for loose connections on AC Rectifier and Microswitch.
For the next portion of the test, remove the upper and lower connections of the
AC Rectifier before applying power.
•Close Microswitch by inserting a time card. Check for AC power voltage
on the left and right terminals of the AC Rectifier. If not, the problem is
most likely a faulty Microswitch – replace both the Microswitch Bracket
Assembly and Rectifier.
•Check for DC voltage between 85vDC and 120vDC for a 120volt clock or
between 170vDC and 240vDC for a 240v clock. If not, replace the AC
Rectifier.
•If Microswitch and AC Rectifier are operational, check the Print Solenoid.
The Print Solenoid should measure approximately 33 ohms (120V) or 144
ohms (240V).
