Mounting the Motor

The MCE-17B motor can be used with all Bolex H camera models.

  1. Remove the winding crank
  2. Push the spring motor disengaging lever down to "0." If any resistance is felt towards the end of this movement, do not attempt to force it but press the front release knob while continuing to move the lever.
  3. Fit the plexiglass adapter over the speed control knob; this will make the latter easier to use when the motor is in position.
  4. Fit the flexible driving shaft of the motor on to the hand cranking spindle (a) of the camera, making sure the pin engages in the corresponding notch of the shaft. Attach the motor to the camera by screwing the upper milled knob in the position usually occupied by the winding crank. Then screw the lower milled knob into the threaded hole (b) provided on all recent H camera models, first removing the small screw covering the hole. The screw should be replaced when the motor is not in use.
  5. On cameras not equipped with this threaded hole, the lower milled knob cannot be used and should be removed from the motor after loosening the holding screw.

Power Supplies

The MCE-17B motor can be powered by standard 6V, 3.5 amp-hour batteries, available from radio stores and Paillard-Bolex dealers, or with any direct current supply at the same voltage, such as an accumulator.

A leather case containing five 6v. 3.5 amp-hour batteries connected to a terminal plate is sold separately. Designed to be carried over the shoulder, this allows complete freedom of movement and is ideal for filming out-of-doors. It also includes a compartment for the motor and the lead.

  • Set the camera speed to the desired speed
  • Move the starting lever (e) at the base of the motor to the "off" position by pulling it outwards
  • Connect the power lead (g) to the motor and to the terminal plate, placing the red plug in the socket marked "0" and the other plug in the socket corresponding to the selected speed. The conductor fitted with an eye is used for connecting the power lead to the terminal plate.
  • Attention. To remove the power lead, push the small metal lock located beneath the 3 pole socket to the right.
Arrangement of batteries

Replacing the batteries

All five batteries will not be used up and need replacing at the same time since some of them are only used occasionally, depending on the filming speed chosen.

H8 cameras

12 to 16 f.p.s. uses batteries 1 and 2

18 to 32 f.p.s. uses batteries 1, 2 and 3

48 f.p.s. uses batteries 1, 2, 3 and 4

64 f.p.s. uses all five batteries

H16 cameras

12 to 16 f.p.s. uses batteries 1, 2 and 3

18 to 24 f.p.s. uses batteries 1, 2, 3 and 4

32 f.p.s. uses all five batteries.

  • To replace batteries, open the case and push back both sides to release the terminal plate, then turn this over on to the lid.
  • Disconnect the discharged batteries and replace them, taking care to position the + and - poles correctly. Follow the diagram on the back of the plate.
  • Re-connect as shown in the diagram. Start by connecting the wire from terminal 12 with the corresponding batteries, then succesively connect those from terminals 18, 24, 30 and 0. These figures represent the nominal voltages obtained at each of the corresponding terminals.

24v. power socket (f) for the MM motor (code CASMO) of the 400 ft. magazine (code CASFA).

The MM motor can only be used if the MCE-17B electric motor is powered by a set of 6 or 8 batteries and used in conjunction with the BXE-70A voltage regulator (code MOREG).

Electrical Release

The camera can now be started directly from the electric motor, or by means of a remote control cable or the "Electric H" grip (code HAFEL).

Release by the motor

Push the side release to "M". Depending on the position of the motor release lever, the motor will drive the camera in intermittent or continuous running.

For intermittent running: pull the lever (e) out. The motor will run so long as the lever is pressed forward and will stop when the lever is released.

For continuous running: push the lever (e) fully home in the motor body.

In reverse: If you should want to change to another type of film when the 100 ft. spool in the camera is not yet fully exposed, there is no need to remove the motor and rewind the film with the hand crank. Instead, note the number shown on the camera counter, then simultaneously press the lever (e) and the grey reverse running knob, marked "R".

Release by remote control cable

A 2 ft. remote control cable (d), equipped with a toggle switch, is supplied with the motor. This is identical to the cable supplied with the MST motor. If the camera is used with the HAFEL grip, its cable should be plugged into the remote control socket.

If a longer remote control cable is required, this can easily be made but care should be taken to ensure that the wire gauge is large enough to prevent a drop in voltage.

Mechanical release

Camera side release on "STOP", press the lever (e) fully home to start the motor. The camera is released as usual with front or cable release. Single frame exposures should not be made as the exposure time may be different from motor to motor. When the camera is stopped, do not let the motor run more than 1 minute in order to avoid premature wear of the motor friction.


Mounted in ball bearings, the motor requires no further lubrication.
