TM 55-1520-240-23-5 6-10 INSPECT DRIVE SHAFTING ON AIRCRAFT     (Continued) 6-10 9. 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. NOTE Move the sync shaft by hand as far forward and aft as possible while making check as clearance may be reduced by shaft rivets. a. Rotate sync shaft at least one full revolution while checking to ensure minimum clearance of  .25 inch  is obtained. b. If clearance is  .25 inch  or less, go to step 10. c. If clearance is more than  .25 inch, no further action is required. NOTE As damage to the sync shafts may occur if correction procedures are done with sync shaft installed, it is recommended the sync shafts be removed. 10. Mark mounting bracket at place where clearance will be obtained. CAUTION Minimum distance from the edge of the mounting bolt hole to the edge of the bracket shall be no less than .244 inch. 11. File/grind excess material required to obtain the required  .25 inch  clearance between sync shaft and the bracket edge. 12. Deburr and remove all metal shavings. WARNING 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. 13. Clean exposed areas of the mounting bracket with acetone (E20). WARNING 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 for eyes. 14. Apply MIL-P-23377 primer (E292) to the bare metal surfaces of bracket. 15.
