MIL-T-60696A(OS)
3.3 Structural strength. The assembled thruster shall withstand a static tensile force of 2,000 pounds,
minimum, for 15 seconds, minimum, between mounting points without unlocking and without mechanical
failure (see 6.3.1).
3.4 Protective finish. Protective finish shall be in accordance with the applicable specifications and
drawings and shall apply to all surfaces of the component regardless of configuration. Remanufactured
exterior components (see 6.4 and 6.5) shall have the existing protective finish stripped and the specified
protective finish reapplied.
3.5 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more
than five degrees in either direction using the procedures of 4.5.4.
3.6 Shear pin strength. The shear pin, after application of protective finish, shall shear when a load of
55 ± 4 pounds is applied at the steady rate of 0.125 inch per minute.
3.7 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to the
requirements of the metal parts assembly drawing. All threaded joints shall be assembled with sufficient
torque to bottom components.
3.7.1 Integrated plant products. When remanufacturing and loading of the assembly is performed in
an integrated plant, the metal parts assembly requirement may be waived and the residual magnetism
requirement performed on the loaded assembly only.
3.7.2 Threaded component parts. Class 2A or 2B thread gage shall be used on remanufactured
component parts inspection versus class 3A or 3B thread gage required on new hardware for thrusters.
3.8 Torque.
3.8.1 Assembly torque. A torque of 100 + 20 inch pounds shall be applied between the body and holding
ring for the purpose of tightening the assembly prior to spotting threads for setscrew installation.
3.8.2 Breakaway torque. The body with respect to the holding ring shall withstand a breakaway torque
application of 400 inch pounds, minimum, without any movement or deformation.
3.9 Piston locking spring and end sleeve. The piston locking spring shall enter the spring hole in the
piston without bending along its entire length. The assembly of the piston locking spring to the end sleeve,
with the cap screw and washer, shall be hand tight. If axial misalignment of the piston locking spring is
evident upon completion of assembly, the cap screw may be backed off sufficiently to eliminate axial
misalignment of the piston locking spring.
3.10 Trunnion rotation. Upon completion of assembly, the trunnion shall be free to rotate 360 degrees.
3.11 End sleeve rotation. Upon completion of assembly, and after structural strength test, the end sleeve
shall be free to rotate 360 degrees in a clockwise direction.
