INSTALL AFT ENGINE MOUNT LINK AND ADAPTER
(WITH 57 )
CAUTION
Adjustable link assembly is
adjusted to set engine cross shaft
alignment at the time of aircraft
manufacture or incorporation of MWO
1-1520-240-50-60. The adjustment
fixture 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.
Aft engine mount links that have
been modified by 57 adjustable link
145PS700-1 must not be replaced
with fixed link 114PS223-1.
NOTE
When installing adjustable link ensure
that ‘up arrow’, located on the link
center body, is pointing towards the
underside of the engine.
NOTE
The engine mount should be installed
so that the lower bearing loader slot
faces outboard. Failure to do so would
allow the mount to twist causing
damage to the airframe lug.
