FREE FALL ATTACHMENT
4. Remove the two spacers (815), ten divider plates
(814), and seven friction plates (813).
Clean and Inspect
1. Thoroughly clean and inspect all parts. Check sealing
surfaces on the free fall housing, bearing support, and
piston. Ensure the free fall release port is clean and
free of debris.
2. Place free fall friction disc on a fl at surface and check
for distortion with a straight edge. Friction material
should appear even across the entire surface with the
groove pattern visible. Replace friction discs or divider
plates if distorted, burned, wear is uneven, or splines
are worn to a point. Minimum thickness of friction ma-
terial is .160 in. (4 mm.) measured at the center of the
friction surface
3. Check free fall spring free length. Minimum free length
is 2.910 in. (73.9 mm.) If it is required by measurement
to replace one spring, you must replace all springs.
