Th e Kodak Instamatic Movie Projectors Models M55-L and M55-P will project SUp·ER 8 films at

a fixed average speed of 18frames per second and can accept spools of up to 200 feet capacity.

A special feature of these machines is an automatic threading mechanism. The film is fed into the picture

gate and the claw mechanism drives the film to engage with a special clutch fitted to the take up spool.

Mains supply

Dismantling the projector

T he p ic tu re g at e assembly To gain access to the gate for cleaning, etc., move the focusing lever up

and pull out the gate pressure-pad plunger. While holding it out move it towards the case when it will latch

in the fully out position.

Th e

gate pressure pad can now be lifted out.

Th e

gate framing plate cannot be removed

however, bu t can be cleaned easily in position with a 'suitable gate cleaning brush.

Th e lens an d cover assembly To remove the lens assembly, take out the gate pressure pad as described

above, and slide the complete lens and cover assembly towards the gate until it is free to lift out.

Th e lens barrel can be removed from the cover assembly by pull ing off the button from the focusing

lever, and then sliding the lever off the lens barrel. Do not attempt to dismantle the lens assembly.

Th e

claw housing assembly To

gain access to the claw and framing mechanism, lay the projector on

its back, take out the gate pressure pad, and using the special screwdriver, remove the three screws from the

claw housing cover. Th e cover can now be lifted off. Take care lot to lose the two film snubber springs and

the mirror assembly which become loose when the cover is removed. To clean the mirror, lift out the components

of the mirror assembly, noting the order of assembly.

Removing th e

claw.

As a precaution before removing the claw, carefully lift out the two snubbers and

the mirror assembly. Then with a pair of pliers, remove the end of the spring

(174537)

which bears in the nylon

bush on the claw and lift out the spring. Remove the claw retaining spring (160360) by pressing down and

twisting it clockwise. If the claw drive cam is in such a position as to prevent the spring being removed, hinge

the mechanism forward and turn the fan blades to move the cam to another position.

Th e

claw can now be

lifted out, bu t do not lose the three ball bearings on which the claw rides.

W RNING

Th e

blades of the cooling fan are brit tle, and can be easily broken by rough handling. In the

event of one of them being broken, the complete fan must be replaced.

Removing t he m e ch a ni sm from

th e

case. Release the captive screw at the top of the mechanism

frame and allow the mechanism plate to hinge forward. Remove the two large screws from the sides of the case,

and the mechanism can now be lifted out.

S e pa r at i ng t he m e c ha nis m plates

Slide the spring fastener

(149624)

from its inounting, and withdraw

the feed spool arm from the front of the projector. Remove the five securing screws (one on the front frame,

and four on the plates), and the two plates can then be pulled apart; note that the shutter shaft and the control

switch mechanism now become loose. Access can now be obtained to all parts of the projector mechanism.

3.2 Re-assembling the

projector

The

majority of the re-assembly is the reverse of the dismantling procedure, but the following points

should be noted:

If

the mechanism plates have been separated, the control switch mechanism will have to be re-assembled

immediately prior to assembling the plates, as the switch is only held firm when the plates are in position. Do

not forget the fiat spring (149668)which sits in the recess of the switch housing.

Th e

drive belt from the motor

can be slipped over the motor pulley after the plates have been assembled.

Th e

insulator

(152807)

is fitted between the mechanism plates in such a way that it prevents the wiring

from becoming entangled with the shutter blades.

If the claw housing cover has been removed, the components of the mirror assembly must be assembled

correctly as shown in the main illustration at the end of the book. Th e mirror must be fitted with the coated side

innermost. These parts are so designed to conduct heat away from the mirror and the picture gate to the claw

housing cover, which acts as a heat sink. Check that the two film snubbers and their springs are seated properly,

and then fit the claw housing cover.

3 3 h take up clutch

The drive to the take-up spindle is made via an adjustable slipping clutch.

It

is set at the factory to

produce a pull

of

between 0.6 and 1.0 in/oz at the take-up spindle, and should not normally require any further

adjustment throughout the life of the projector. If the take-up spool persistently fails to take-up when fully

loaded, or

if

it presents an excessive amount of drag to the film

leaving

the gate, then attention to the take-up

clutch is indicated. Before adjusting, however, make sure that a slipping take-up is not due to a worn or stretched

drive belt.

To

adjust the clutch tension proceed as follows. Hinge the mechanism forward from the case and note

the take-up clutch at the rear of the take-up spindle. The adjustment of tension is made by the three-pronged

adjuster which rides on the cam faceinside the clutch. Move the adjuster up the cam face to increase the tension,

and down the cam to decrease the tension.

3 4 Electrical circuit

The wiring diagram for the M55-L is shown in Figure 2.

It

will be seen that the motor and lamp are

connected in a series circuit together with the tapped ballast resistor.

The

failure

of

anyone

of these components

will, therefore, prevent the projector from functioning.

The

wiring diagram for the M55-P is shown in Figure 3. When set to the 220-240 volts range, the circuit

is similar to the standard model, and when set to the 115-130 volts range, the motor and lamp are connected in

parallel, and

th e

ballast resistor not used.

The

motor is of the shaded pole induction type and normally runs hot. The speed is dependent on the

mains voltage, but should give a final projection speed of between 15.5 and 19 frames per second.

Symptom

Projector will not run.

Lamp will not light.

When the M55-P is switched to the

115-130volts range, the motor and

lamp are in a parallel circuit and

the possible causes listed will not

apply. The failure of one will not

prevent the other from function

ing.

Poor illumination.

Claw damages film.

Take-up and re-wind mechanism

slipping.

Excessive vibration.

Overheating.

Note: The motor and claw housing

cover normally run hot.

Lamp bracket

The

mounting bracket for the lamp is adjustable to compensate for small changes in

lamp filament position when new lamps are fitted. To adjust, remove the small plastic bung from the hole in

the front of the projector case, insert a screwdriver, and turn the eccentric screw to give the best possible

evenness of illumination with no film in the gate.

law position There are two adjustments which affectthe clawposition. They should be set so that with

a piece of film threaded in the gate the claw enters the perforation holes exactly in the centre each time. The

claw must

not

touch the film as it enters the holes.

Refer to Figure 1. Insert an 8-BA flat spanner through the slot in the claw mechanism cover and adjust

the hexagon headed screw to' centre the claw laterally. If the claw stroke is incorrect, use a 6-BA Allen key to

adjust the 'Claw
