The Head
Description: The following text deals with the basic head and the
movements, Eye turn, Eye lid, Mouth and Ears. There
are drawings at the back of the text depicting the
movements in the head, (Pages 3-045 and 3-046) use
these drawings for reference only. Critical
adjustments on each movement will vary with each
character, so after doing any repair work refer to
Pages 3-094 thru 3-135 and set the Critical
Adjustments. All part numbers are available in the
Parts Catalog.
A. If the head must be removed from the character to replace or
rebuild the hinge:
1. Label the air lines attached to the cylinders, then cut off
or pull off the lines. Make sure the air lines are labeled
so that they can be reattached properly.
2. Detach the Head Up, Down cylinders front mount, and the
Head Tip Cylinders front mount as required to free the head.
3. Unscrew the E-Hinge at the T-Top of the neck shaft.
Only disassemble a hinge while it is still attached to the
character if absolutely necessary. (It is best to work with
the part in a vise)
B. The eyes left, right and ear movements use Clippard cylinders.
They are not repairable and must be replaced if bad.
1. The front and rear mounts of these type cylinders have been
attached using two different ways, some using 1/8" Dowel
Pins and Shaft Collars, now we use 1/8" x 3/4" Cotter Pin
Part # 28-045-957.
2. Bend the Cotter pins closed, or loosen the Shaft Collars and
remove the cylinder.
3. Cut or pull off the air lines to the old cylinder. Attach
them to the new cylinder. Pull and re-attach the lines one
at a time so you don't get them mixed up.
4. Re-attach the new cylinder to the front and rear mounts
using a 1/8" x 3/4" Cotter Pins, set the critical
adjustments. (Pages 3-094 thru 3-135)
