MIL-DTL-6193D
4.7.2 End and side play (see 3.5.2). Both the end play and side play of the universal joints shall be
measured and shall meet the requirements of 3.5.2. The following details shall apply:
a. Class 2 universal joints the lubricant retaining cover shall be removed for this test.
b. Lubricant shall be removed for this test.
c. For each measurement, a five-pound (2.27 kg) load shall be applied to obtain an initial
reading.
d. The load shall then be reversed and a second reading taken.
e. The total play is the play recorded between the two readings.
f The side play of the universal joint shall be measured in the same plane as an inspection hole.
g. The side play is measured a second time with the universal joint rotated 90 degrees from the
first side play measurement.
4.7.3 Axial load (see 3.5.3). The axial load for a particular type and size of universal joint shall meet
the requirements of 3.5.3. The following details shall apply:
a. The axial load shall be applied in both tension and compression directions for 30 seconds with
angle A, as shown on figure 1, equal to 0°.
b. After application of the axial load, the universal joint shall be inspected for permanent
deformation and for tightness in accordance with 4.7.4.
4.7.4 Tightness (see 3.5.4). Tightness for universal joints shall meet the requirements of 3.5.4. The
following details shall apply:
a. Universal joints shall be tested for tightness with the lubricant retaining cover removed and
may be lubricated during the test.
b. The lower end of the universal joint shall be clamped in a vertical position.
c. The moment of force required to move the upper end of the universal joint through the
minimum angle of 30° shall be measure.
4.7.5 Static torque load (see 3.5.5). The universal joint when subjected to static load test shall meet
the requirements of 3.5.5. The following details shall apply:
a. The universal joints shall be subjected to 90% of the static torque load specified in table II,
without exceeding 12° torsional deflection and shall not fail.
b. If no failures occurred during the 90% static load test, the same universal joints shall then be
subjected to 100% torque load shown in table I and shall not fail.
4.7.6 Torsional play (see 3.5.6). Universal joints subjected to torsional play shall meet the
requirements of 3.5.6. The following details shall apply:
a. With the lubrication retaining covers and lubricant removed, the applicable torque specified in
table I under "Torsional play" shall be applied to the universal joint to obtain an initial reading.
b. The torque load shall then be reversed and a second reading taken.
c. The torsional play at the circumference of the universal joint is the difference between the two
readings.
(1) The torsional play for samples that have not been subjected to endurance testing shall
not exceed the limits specified in 3.5.6.
(2) The torsional play for samples that have been subjected to endurance testing shall not
exceed 5°.
