Shift

SYMPTOM

POSSIBLE CAUSE

REMEDY

REMARKS

Machine will not

shift to upper

case.

1. Shift key binding on cover

(84-18)

Adjust machine within covers.

Adjust with machine foot brackets

(65-30).

2. Upper case shift spring

off or damaged.

Replace shift spring (84-20).

3. Worn or broken shift

spring (62-22).

Replace shift spring and lubricate.

4. Shift clutch spring re-

taining plate loose or

maladjusted.

Retaining plate controls clearance

between shift arbor (3-2) and

Loosen two screws (3-4) holding

retaining plate (3-3) and rotate

spring until machine detents

properly in upper case position.

Check shift detenting by:

1. Turn machine on.

2. With your finger, push up on

the front end of the shift detent

arm (62-20) and rotate it away

from the shift cam (62-21).

3. Shift machine to upper case

and hold it there.

4. Slowly, allow the shift detent

to return to the detent position

on the shift cam. The reentry

of the detent should not cause

the shift cam to move.

5. Shift arbor worn or loose

(3-2)

Replace or tighten arbor.

If shift arbor is replaced, readjust operational shaft end play.

6. Shift release

Observe shift release lever (69-40)

releasing shift cam ratchet (62-24)

7. Shift interlock (69-38)

holding shift cam ratchet

(62-24).

cam ratchet.

8. Shift ratchet (62-24)

binding on release lever

(69-40).

Adjust release lever (69-40) link,

and or check for binds.

9. Overthrow stop broken

or loose (69-42).

Replace or readjust overthrow

stop (69-42).

adjust a clearance of .020"

between shift overthrow stop

(69-42) and lug on shift ratchet

(62-24).

10. Filter shaft gear dam

aged or loose (47-34).

Replace and or readjust filter

shaft (55).

See alignment section

11. Filter shaft out of adjust

ment.

Adjust filter shaft (55)

See alignment section

12. Shift brake broken or

damaged (69-39)

Adjust shift brake for 1/2 bite on

brake surface of shift cam

Keyboard locks

after shifting.

1. Shift lock

Check shift lock and spring (84-18)

2. Shift spring retaining

plate (3-3)..

Check for damage and adjust shift

plate (3-3).

3. No lubrication

Lubricate shift mechanism com

pletely.

Lubricate shift spring only with

grease.

4. Overthrow stop (69-42)

Replace or adjust overthrow stop

(69-42).

With shift cam in detented position

adjust a clearance of  .020"

between shift overthrow stop

(69-42) and lug on shift ratchet

(62-24).

5. Character interrupter

(49-40)

1. Loosen screw (49-42) and nut

(49-41), adjust character

interrupter pawl (49-40) for

clearance between pawl (49-40)

and cycle clutch link (49-44).

2. -1 Remove electrical cord from outlet.

2 Depress character key to release cycle clutch.

3 Loosen screw (49-43) and

adjust for  .001" clearance

between cycle clutch link

(49-44) and character inter

rupter pawl (49-40).

6. Shift ar bor worn or loose

(3-2).

Replace or tighten arbor.

If shift arbor is replaced, read

just operational shaft end play.

Typewriter shifts

up and down

1. Shift spring broken (62-22)

Replace spring.

2. Shift release arm broken

or binding (69-40).

Replace or release binds and

lubricate (69-40).

3. Shift spring clutch retaining plate broken (3-3)

Replace and adjust.

For adjustment see "Machine will not shift to upper case, cause 4".

Machine will not

stay in upper

case shift position.

1. Shift latch plate worn or

maladjusted (86-22).

Adjust shift latch plate (86-22) so

shift will lock in upper case

position and hold, when keybutton

is depressed 2/3 distance.

Shift latch plate adjusting screws

shown (86-22).

2. Shift latch spring broken

or missing.

Replace and lubricate mechanism.

3. Shift release mechanism

binding.

Check and adjust shift release

lever (69-40) to release shift

ratchet as shift locks in upper

case position.

Lubricate shift mechanism and

check for binds.

Machine locked

in upper case

shift position.

1. Shift key binding on cover

Adjust machine within covers.

Adjust machine foot brackets

(65-30).

2. Shift lock binding or

damaged.

Shift latch is part of shift lock

keylever (84-18).

Remove binds and lubricate.

3. Spring missing or dam

aged from shift lock.

Spring is attached to shift lock

on keylever (84-18)

4. Shift interlock maladjust

ed or has burrs on it.

Remove burrs and adjust shift

interlock (69-38) for clearance

between interlock and shift ratchet

teeth at rest position (62-24).

5. Shift clutch retaining

plate (3-3).

Retaining plate controls clearance

between shift arbor (3-2) and shift

spring (3-1).

For adjustment see "Machine will not shift to upper case, cause 4".

Shift sluggish

1. Shift key binding on cover

(84-18).

Adjust machine within covers.

Adjust machine foot brackets

(65-30).

2. No lubrication

Lubricate shift mechanism com-

pletely.

Shift spring (62-22) must be lubed

with grease only; no oil.

3. Shift release maladjusted

or damaged (69-40).

Adjust shift release lever (69-40)

to release cam ratchet (62-24) as

shift locks in upper case position.

4. Shift clutch spring retain

ing plate. (3-3)

Replace if broken and or adjust.

For adjustment see "Machine will not shift to upper case, cause 4".

5. Shift overthrow stop

(69-42).

Replace or adjust overthrow stop.

With shift cam in detented position

adjust a clearance of  .020"

between shift overthrow stop

(69-42) and lug on shift ratchet

(69-24).

6. Shift arbor worn or loose

Replace or tighten arbor (3-2)

If shift arbor is replaced, readjust

operational shaft end play.

7. Shift ratchet (62-24) bind

ing on release lever

(69-40)

Adjust release lever (69-40) so

ratchet (62-24) is released when

keybutton is depressed 2/3 distance .

8. Operational shaft end

play.

Operational shaft end play is con-

trolled by shift arbor (3-2) and

collar (8-10) on inside of machine,

right side of operational shaft.

Operational shaft end play should

be minimum - no binds.

9. Shift cam backup roller

or stud worn. (85-21).

Shift cam backup roller is adjust-

able on early machines.

Not adjustable on later models.

A worn backup roller could case

shift cam to vary position, thereby

changing rotate alignment.

10. Shift brake broken or

maladjusted (69-39)

1/2 bite on brake surface of shift

cam.

Malselection or

Horizontal align

ment problems

after shift.

1. Shift clutch retaining

plate (3-3).

Check for damage and adjust shift

plate (3-3).

For adjustment see "Machine will not shift to upper case, cause 4".

2. Character interrupter

(49-40).

For adjustment see "Keyboard

locks after shifting, cause 5".

3. Shift interlock (69-38)

Check interlock for interference

and adjust to release cam ratchet.

(69-42).

With shift cam in detented position

adjust a clearance of .020"

between shift overthrow stop

(69-42) and lug on shift ratchet

(62-24).

5. Shift motion has binds.

Observe operation of shift mech

anism for variations in movement

of parts and binds.

6. Worn or loose shift arm

roller (69-37).

Causes variation in rotate detent

ing.

7. Shift cam backup roller

(85-21).

Shift cam backup roller is adjust-

able on early machines.

Causes variation in rotate detent

ing.

8. For further causes see
