Adjustable link 145PS700-1 is
adjusted to set engine cross shaft
alignment at the time of aircraft
manufacture or incorporation of MWO

fixtures are unique and are not
interchangeable. This preserves the
proper link length measurement for
each engine should the link need to
be replaced or adjusted.

modified by 57 with adjustable link
145PS700-1 must not be replaced
with fixed link 114PS223-1.
