The Legs and Pelvis Cont.
4. The body lean front mount (D) is bolted to the chest, and
has a cylindrical bushing pressed into it. The bushing used
in the mount is a 3/8"I.D. x 1/2"0.D. x 1/2" long.
(Part #28-032-020) The bushing may become sloppy due to wear
and tear. If the bushing is allowed to wear to a point where
the hole it's pressed into is elongated and the bushing
falls out, replacement of the front mount is required. To
replace The bushing:
a. Detach the cylinder from the front mount, support the
body by placing two pieces of metal and a clamp at the
pelvis hinge (E).
b. Unbolt the front mount from the chest. Fatz front mount
bolts also hold the rear Fiberglass Body part onto the
character so removal of it is necessary.
c. Using an Arbor press and a 7/16" steel pin, press out the
old bushing. If an Arbor press is not available use a
hammer and steel pin.
d. Press in the new bushing. Hand ream it and make sure it
will attach easily to the Body Lean cylinder. File the
sides of the bushing if it won't fit on the cylinder's
front mount clevis.
e. Re-attach the front mount to the chest and cylinder, set
the critical adjustments.
B. The Body Turn movement (See Drawing Page 3-073) is a 4 way
movement. This is accomplished by attaching two cylinders back
to back. For any problems in the cylinder refer to Pages 3-009
thru 3-011, and all drawings referred to by that text. The two
mounts to the cylinder are both collar pins (F), replace them
if they break, (Numbers are in the Parts Catalog) then, set the
critical adjustments.
1. If the weld attaching the steel pelvis mount plate (B) to
the twist shaft breaks, replacement of the welded part is
required. If this happens the body turn movement is under
a lot of stress. Check over and rebuild the cylinders if
necessary, see Pages 3-009 thru 3-011, and all drawings
referred to by that text.
