weight fitting (11). Use chart 2.
b.
Move required number of tracking weights (7)
from aft fitting to forward fitting.

Remove weight from upper tube of aft
fitting first. If additional weight must
be shifted, remove weights from lower
tube.
c.
Move an equal number of spacers (6) from
the forward tube fitting to the aft tube fitting.

Install span balance weights and tracking weights
as follows:
a.
Measure depth of aft tube(s) (10) and forward
tubes (11). Record dimension.
b.
Measure total length of weights (7 and 8),
spacers (6 and 9), and end cap (4 and 5).
c.
Compare dimensions from steps a and b.
Length of assembled weights, spacers, and
end cap must be same as depth of tube. If
not, cut new wooden spacer (APP E-44) (9)

NOTE
When weights, spacers and end caps
