Props and Looney Bird
G. The Looney Bird Hands (See Drawing Page 3-089) mechanism is
simple and should have few problems, other than normal wear and
tear.
1. For any problems in the cylinder, refer to pages 3-009 thru
3-011, and all drawings referred to by that text. All part
numbers are available in the Parts Catalog. After any repair
work refer to Pages 3-094 thru 3-135 and set the critical
adjustments. For any problems in the fur hands, refer to
Pages 3-136 thru 3-187, Cosmetics.
2. The Actuation Block and Plate (C) are joined using a steel
pin, that is pressed into place at the factory. If the
bushings in the Actuation Block (C) need replacing:
a. Detach the cylinders front mount from the Plate (C).
(Note the location of the washers (L) in the assembly)
b. Detach the Actuation Block (C) from the carrier (A), by
unscrewing the two screws (D) •
c. Using a Arbor press and a steel pin, press out the steel
pin. If an Arbor press is not available use a hammer and
a steel pin. Press out the old bushings, and press in the
new, if a tight press is not available mar the hole using
an Awl, if that does not wor~ replace the Actuation Block
and Plate. (The bushings used in the block are 1/4" I.D.
x 3/8" O.D. x 1/4" long Part # 28-032-210) Press the 1/4"
steel pin back through the block and plate.
d. Re-assemble the mechanism, double check your work, and
set all critical adjustments.
3. If the lower mount support pieces, for the plastic block (F)
and plastic page (I) should move, the plastic block (F)
could be damaged beyond use. To replace it simply remove
the rear mount pieces, and allow the block (F) to come off
the Guide Shaft (E) • Replace the block and reattach the
old plastic page (I).
4. The plastic page could break if mishandled, to replace it
simply unscrew the page from the block and replace with the
new one.
