❑ Figs. 26 & 27 Still working with bag #2 remove the
#4524 graphite T-bar brace, one #4519 4-40 x 9/16” FHSScrew,
one #6915 4-40 x 5/8” FHSScrew, one #4449 4-40 small
aluminum locknut, and the #4515 aluminum dampener center
post. From the bottom of the chassis install the #4519 screw
into the front T-bar mounting hole and the #6915 screws into the
back T-bar mounting hole. Place the T-bar assembly over the
two screws as shown. Now place the #4524 graphite T-bar
brace over the two mounting screws. Thread the #4449 locknut
onto the front mounting screw to secure the front T-bar pivot to
the chassis. Now take the #4515 center post and thread it onto
the #6915 screws coming up through the rear pivot ball. Go
ahead and tighten both pivot balls against the chassis. Note:
You may want to hold the #4515 aluminum center post with your
needlenose pliers while you tighten the #6915 rear mounting
screw.

Fig. 28 Now find and open bag #3. Start by removing
the two #4442 aluminum chassis brace standoffs and two
#7673 4-40 x 5/16” FHSScrews. You will be using the two
#7673 screws to secure the #4442 standoffs to the back
corners of the chassis.

❑ Figs. 29, 30 & 31 Take out the #4534 graphite
rear chassis brace. Also remove the #4516 plastic dampener
post and one #6917 4-40 x 3/8” BHSScrew. Look at the chassis
brace. There are two holes at the center area. One along the bar
portion and the other on a small section protruding from the
center. Secure the plastic dampener post to the hole in the bar
portion of the brace using the #6917 screw. Use #242 Loctite
to secure the damper post to the screw. This way it cannot
come unthreaded when you remove the top screw in the post
for normal maintenance or adjustments.
Now remove three #6917 4-40 x 5/16” BHSScrews
from bag #3. Place the rear chassis brace on top of the three
aluminum tubes as shown. Line up the three mounting holes
and use the three #6917 4-40 x 5/16” BHSScrews to fasten the
brace down to the tubes.
