3.3 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) shall have the existing protective
finish stripped and the specified protective finish reapplied.
3.4 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 4.5.3.
3.5 Shear pin strength. The shear pin, after application of protective finish, shall shear
when a load of 48 4 pounds is applied at the steady rate of 0.125 inch per minute.
3.6 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.
3.6.1 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.
3.6.2 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.
3.6.3 Piston locking spring and end sleeve. The piston locking spring shall enter the spring
hole in the piston without any bending along its entire length. If axial misalignment of the
piston locking spring occurs, the cap screw may be backed off sufficiently to permit alignment.
3.6.4 Trunnion rotation. Upon completion of assembly, the trunnion shall be free to rotate
360 degrees.
3.6.5 End sleeve rotation. Upon completion of assembly, the end sleeve shall be free to rotate
360 degrees in a clockwise direction.
3.6.6 Reclaimed parts. Remanufactured thruster parts which may be reclaimed shall meet the
following requirements:
a. Piston. Only pistons with 1/2 inch length from back face to O-ring groove and 5/8 inch
length from front face to back face of key escape groove shall be reclaimed.
Nonconforming pistons which have the unlocking undercut of 9/16 inch length shall be
modified to meet the 5/8 inch length requirement of Drawing 8593867. Touch-up plating
to the machined area is acceptable.
b. Head. Only heads with internal bore diameter of 0.337 + 0.009 inch and no setscrew
holes shall be reclaimed.
c. Body. Only bodies suitable for nylon pellet type thread fastening shall be reclaimed.
The nylon pellet shall be located 0.775 0.015 inch from end of body. The chamfer on
