4. Another thing to go wrong with the Guitar Rock movement is,
the 5/8" Pillow Block Bearing (E) breaks. This is usually
caused by the adjustment on the Actuation Lever (C) being
off. If pillow blocks break check the critical adjustment.
(See Pages 3-094 thru 3-135) For any broken or worn parts
that need replacing in the Guitar Rock movement follow the
steps described below, part numbers are available in the
Parts Catalog.
a. Label and pull the Air lines attached to the Hand Slide
movement cylinder in the Guitar.
b. Detach the guitar from the guitar mount plate (F), and
place it to the side.
c. Pull the Fas-Pin in the Guitar rock cylinder's front
mount.
d. Tap out the Roll Pin in the Actuation lever, using a
steel pin and a hammer.
e. Loosen the set screws in the Pillow Blocks (E) and the
Actuation Lever (C), and pull the twist shaft from the
assembly.
f. Unbolt and remove the broken Pillow Block (E), and
re-attach the new block using the same bolts previously
removed.
g. Check the twist shaft (D) to see if it is bent. File
off any burs on the twist shaft.
h. Re-assemble the mechanism, re-attach the guitar and air
lines. Don't forget to tighten all set screws and tap
back in the Roll Pin, set the critical adjustments.
5. The Hand Slide movement (See Drawing Page 3-058) is a simple
push-pull type mechanism. Most of the recorded problems in
this movement are caused because the mechanism is located on
the outside character and is more easily damaged. The newer
Guitars will have two Shaft Guide Blocks (D). The older
Guitars use only one Shaft Guide Block (D), welded to the
neck, near the end of the neck.
