MIL-T-85703(AS)

Repeat step 5 except run the tool in the counterclockwise

direction.

7. Test the torque limiter by adjusting to 20 ft-lb and installing

the tool as in step 4.

8. Run the tool in the clockwise direction with a 15 ft-lb load,

then, rapidly increase the torque load to activate the torque limiter.

Continue to run the tool for five seconds with the torque limiter activated.

Record the torque limiter actuation torque, voltage and amperage draw.

Repeat step 8 except run the tool in the counterclockwise

direction.

10.

Increase the torque limiter to a 50 ft-lb capacity and the

dynamometer to a 40 ft-lb load. Perform steps 8 and 9.

4.6.2.3 Test stand and fixtures. The suggested test stand, as shown in

figure 1, supports the unit in its normal orientation at its normal support

position. A dummy output shaft is coaxial to a pneumatic activated disk prony

brake. The prony brake is trundled on self aligning ball bearings. A moment

arm fastened to the prony brake housing is coupled to a force scale that is

reached at the test stand base. The force scale reads pounds in either

The specified torque level requirements are met by regulating the

direction.

pressure to the prony brake. Torque is measured by multiplying the length of

the moment arm by the pounds of force recorded on the scale. Output shaft

speed is monitored by a magnetic speed pick-up feeding off of a 60 tooth gear

pressed on the unit output shaft. Voltage and current are monitored by

dedicated meters.

4.6.3 Examination.

Tools shall be inspected for conformance to the

requirements of this specification and DL1167AS100, with respect to parts,

material, design, construction, lubrication, input power, finish, marking, and

workmanship (see 3.2, 3.3, 3.4, 3.5, 3.9, 3.10 and 3.12 respectively).

4.7 Inspection of packaging. The sampling and inspection of the

preservation-packaging, packing and container marking shall conform to this

specification (see section 5).
