TB 9-1000-234-13 2-6 c. Replenisher. (1) Replenisher may be exercised with either oil pump M3 or an 8-ounce filler gun. (2) Drain fluid from replenisher into a clean container. (3) Attach oil pump hose loosely into filter plug hole. Force air out of hose, tighten hose, and pump fluid into replenisher. Fill replenisher until indicator tape shows smooth edges. (4) Drain replenisher until the proper reading is showing on the indicator tape. (5) Using an oil spray gun, spray petroleum base hydraulic fluid (MII-H-46170 FRH) to the inner surface of replenisher cylinder. This is accomplished by placing the nozzle of gun into each hole alongside indicator tape and alongside tape through the center hole. This procedure should be repeated each time cannon is exercised. NOTE The replenisher is exercised independently, but in conjunction with exercising the recoil mechanism. The recoil mechanism cannot be exercised through the replenisher. d. Hydraulic Jack. Position vehicle (tables 2-1 and 2-2) so that hydraulic jack can be placed between protected cannon muzzle and a vertical, solid, immovable object. • Ensure that cannon bore is square with object, and jack is placed parallel with bore and at right angle to the side or flat face of the object. • Make sure traversing and elevating controls are locked in place before operating jack to move weapon out-of-battery. • Repeat movement at least three times. Lubricate as specified in paragraph 1.3e. e. Wrecker M62, M543A2, M816, M977, or M98E1 HEMTT and Improvised Exercising Bracket. When exercising a number of combat vehicle recoil mechanisms, an improvised exercising bracket (figure 2-1) can be fabricated to save time and effort. With this exercising device, any number of combat vehicles (tables 2-1 and 2-2) can be exercised by using the wrecker boom and exercise recoil mechanism as outlined below. • Ensure that turret lock is engaged and vehicle master switch is off. • Ensure that wrecker boom and gun tubes are horizontally and laterally squared to prevent damage to the tube, turret and other components. • Operators should be in both vehicles to keep brakes fully applied to prevent movement of either vehicle while tube is being pushed out-of-battery. (1) Using black paint, stencil a 1-inch by 6-inch stripe on cannon tube 6 to 8 inches from the gun shield. CAUTIONs CAUTIONs
