= 0.56 in (14.3 mm).
Wear pad thickness (t
wp
) = 0.44 in (11.1 mm).
Add shims as required [each shim is 0.03 in (0.8 mm)] to
tighten the pads so that there is 0.03 in - 0.09 in (0.8 mm -
2.4 mm) total clearance between the sections. In some
cases it will be necessary to have an unequal number of
shims behind the pads at the top and bottom side pad
locations.
At each pad location add qty-1 0.06 in (1.6 mm) and qty-
1.03 in (0.8 mm) shim for a total clearance of 0.03 in
(0.76 mm).
