INSPECT DRIVE SHAFTING ON AIRCRAFT (Continued)
Check clearance between any aircraft non
rotating structure (pay particular attention to the
shaft mounting brackets) and the rotating sync
shafts are at least .25 inch.
Move the sync shaft by hand as far
forward and aft as possible while
making check as clearance may be
reduced by shaft rivets.
Rotate sync shaft at least one full revolution
while checking to ensure minimum clearance
of .25 inch is obtained.
If clearance is .25 inch or less, go to step 10.
If clearance is more than .25 inch, no further
action is required.
As damage to the sync shafts may
occur if correction procedures are
done with sync shaft installed, it is
recommended the sync shafts be
Mark mounting bracket at place where clearance
will be obtained.
Minimum distance from the edge of
the mounting bolt hole to the edge
of the bracket shall be no less than
File/grind excess material required to obtain the
required .25 inch clearance between sync shaft
and the bracket edge.
Deburr and remove all metal shavings.
Acetone (E20) is extremely flammable.
It can be toxic. Avoid inhaling. Use
only with adequate ventilation. Avoid
contact with skin, eyes, or clothing.
Keep away from heat, spark, or open
flame. In case of contact, immediately
flush skin or eyes with water for
at least 15 minutes. Get medical
attention for eyes.
Clean exposed areas of the mounting bracket
with acetone (E20).
Epoxy primer (E292) is extremely
flammable and very toxic. Protective
clothing or body suit with respirator
and eye protection is required
if material is to be applied by
spraying. Avoid inhaling. Use only in
well-ventilated areas. Avoid contact
with skin, eyes, or clothing. Keep
away from heat, spark, or open flame.
In case of contact, immediately flush
skin or eyes with water for at least
15 minutes. Get medical attention
Apply MIL-P-23377 primer (E292) to the bare
metal surfaces of bracket.
Install sync shaft (if removed).
Repeat step 9.
Close drive shaft tunnel access covers (Task 2-2).
