4.6.4.9.3.17.3 Stabilized mode. Conformance to 3.5.9.3.17.3, shall be determined in conjunction with 4.6.4.9.6.3, and table XIII solutions. After superelevation, final lay on target in both azimuth and elevation shall not require more than 4 mils.

4.6.4.9.3.18 Hydraulic fluid. To determine conformance to 3.5.9.3.18, the hydraulic fluid shall be tested in accordance with MIL-H-46170.

4.6.4.9.3.18.1 Cleanliness. To determine conformance to 3.5.9.3.18.1, the fluid in the hydraulic power supply reservoir shall be tested for cleanliness of table VI and the water content specified.

4.6.4.9.3.18.2 Leakage. To determine conformance to 3.5.9.3.18.2, the turret and gun control system components shall be wiped clean before performing the test. During or after five cycles

of elevating the 105mm gun in the interference zone, the leakage from the deck clearance valve shall not exceed that specified. During or after road tests, the vehicle shall be examined for

leakage in the hydraulic system not to exceed the amount specified.

4.6.4.9.4 Cupola weapon control.

4.6.4.9.4.1 Traverse effort. To determine conformance to 3.5.9.4.1, a torque gage shall be attached to the cupola traverse mechanism and the torque measured to start cupola motion. Breakaway torque to start motion shall be as specified.

4.6.4.9.4.2 Elevation effort. To determine conformance to 3.5.9.4.2, a torque gage shall be attached to the screwjack handle and breakaway torque shall be determined for the directions specified. All three characteristics shall be within the limits specified.

4.6.4.9.4.3 Elevation limits. To determine conformance to 3.5.9.4.3, the cupola weapon shall be elevated and depressed to its extreme limits and the angle measured. Elevation and minimum depression limits shall be as specified.

4.6.4.9.5 Fire control system. To determine conformance to the requirements of 3.5.9.5, verify that the requirements specified in 3.5.9.3 have been met.

4.6.4.9.5.1 105mm gun sighting system.

4.6.4.9.5.1.1 Synchronization. To determine conformance to 3.5.9.5.1.1, perform the following test on the vehicle:

a. Position the vehicle on the level ground with a 15° ramp abutting the rear tracks. b. The gun tube shall be leveled, laying from low to high.
