1 - In Bag 2, find the graphite
bottom plate [10]. Secure it to the
pivot ball assembly with the ½” flat
head screw [5]. Secure it tight with
the red hex standoff [11].
2 - Find the 4 red low profile balls
[12]. Secure them as shown with
the steel 5/16” screws [13]. When
secure, pop the plastic side links
[14] on the balls so that the flat
side of the ball sockets face the
center of the car.
3 - Insert the 2-56 button head
screws into the side links from the
outsides of the chassis as shown,
and only tighten them enough so
that the links will not pop off the
balls. You want the links to pivot
very freely without any drag.
Be sure the 2 aluminum locknuts on top of the center pivot are slightly loose.
There should be a washer under each alum locknut. Notice that the center pivot
“floats" or moves slightly on the 2 screws. This "floating" allows the links
to "free up". This ensures that the rear bottom plate pivots freely on the links
and center pivot ball. This is a crucial step when setting up the Gen-XL.
Snap the 2 links on the balls as shown above. They should rock freely on
the pivot balls.
Place the chassis/backplate on a flat surface. No tires and
no diff on the car! A smooth table or desk should do. Be
sure that the rear bottom plate and chassis are in a
straight line, flat against the table, again, no tires on the
car. Lightly “tap” the chassis and rear pod releasing any
tension in the links. Keep the chassis flat on the table for step 4.
Holding the chassis at the hold point “H”
by pressing
the chassis down to the table. Slowly tighten the 2 locknuts that
secure the center pivot. For now, just lightly
snug one side then the other.
Pick up the car and check the pivoting action of
rear lower plate. Rotate the rear plate from side-to-
side. It should move free without binding or "clicking".
If it does not, loosen the pivot locknuts and repeat steps 3+4.
If it rotates smoothly, tighten the locknuts on the center pivot more
securely. Do this by again holding the chassis down to the table at the
hold point “H”. Slowly and carefully fully tighten the locknuts that hold the center
pivot to the chassis. The handling of the Gen-XL hinges (pun intended!) on the
free movement of this rear plate. Be sure that the rear links and rear plate are free and not binding.
