MIL-V-62008B(AT)
4.5.1.40.7 Simultaneous use of power and manual control tests. To determine conformance to 3.6.13.5, the gun shall be elevated and depressed by power while traversing the turret with the manual controls. The gun shall be elevated and depressed by manual control while traversing the turret with power control. The elevation and traverse power switch shall be turned on and off not less than three times and the gun observed for movement.
4.5.1.40.8 Override control test. To determine conformance to 3.6.13.6, the override control switch shall be operated as specified and the control and movement of the gun observed. The commander override switch shall not be reactivated at intervals or less than 10 seconds.
4.5.1.40.9 Control system dead spot test. To determine conformance to 3.6.13.7, gunner and commander control handles shall be operated as specified and deflection of the handles to initiate movement of gun shall be measured with inspection equipment. When measuring the dead spot angle, the control handles shall not be moved toward the neutral center once the gun and turret have begun to move.
4.5.1.40.10 Gun elevation speed test. To determine conformance to 3.6.13.8, the gun shall be elevated and depressed at specified speeds by use of the gunner and commander power controls and the gun speed measured for maximum and minimum conformance. Observe the gun speed control at any rate between minimum and maximum speed.
4.5.1.40.11 Turret traversing speed test. To determine conformance to 3.6.13.9, by use of gunner and commander power controls, the turret shall be traversed clockwise and counterclockwise as specified, and minimum and maximum speeds shall be measured. Observe the turret speed control at any rate between minimum and maximum speed. The accumulator shall be fully charged prior to beginning the maximum speed test. Maximum traverse speed shall be determined by measuring time for the turret to complete 1 revolution from a standing point.
4.5.1.40.12 Main gun stability. To determine conformance to 3.6.13.10, the following test shall be performed with the vehicle nose down on a 15 slope, main gun horizontal, and 90 to the vehicle front to rear axis, turret power switch on, and engine inoperative:
a. Using the gunner telescope and manual elevation handle, aline the main gun on a target within 1 of horizontal.
b. Install a magnetic base dial indicator with a minimum 1 inch range on the turret roof and set it at a predetermined point on the gun breech.
c. Install a similar indicator on the race ring and set it at a predetermined point on the race ring gear.
d. Using the telescope and power control handle, depress and traverse the gun at least 15 mils off-target (without overloading either indicator) and then return the gun to the original target (a) without overshoot.
