Fortunately, they met with very light resistance. A total of 15 DEUCEs (the amount they were purchased for is unknown) are in service with the Royal Engineers. They are funded for and installed by units or through attrition. The sprocket wheel – which is visually similar to the sprocket wheel on the WW2 M3 half-track – is located high and rear, while the idler at the front also performs the role of a road-wheel. This is mostly used to pull trailers. The outer one tends to bend and is difficult to fabricate, resulting in producibility delays and lengthy NMCS downtime. 1942 Combat Damage Analysis of the T-34 and T-70 tanks, 19′ 3” x 9′ 7” x 9′ 1” (5.8 x 2.9 x 2.7 meters), Caterpillar 3126 Hydraulic Electronic Unit Injector with dual power settings: 185hp (earthmoving mode), 265hp (self-deploy mode). The 10th Mountain Division (Light), based at Fort Drum, New York were the first to receive the M105 DEUCE, with the vehicles arriving in May 1999. Finally, the compensating pump adjustment will be improved by replacing the existing adjusting clamp with an adjusting screw and jam nut. Again, the objective is to transmit the correct on-hand amount of fuel, by platoon, to the company executive officer or command post. Ground Clearance: 13in (33cm)
This phase includes a variety of track, hull and blade enhancements. It is a valuable support vehicle to armored, mechanized and infantry units. The DEUCE is air deployable and can be carried by C-130 Hercules, C-141 Starlifter, C-5 Galaxy or C-17 Globemaster cargo aircraft. In earthmoving operations the apron and blade are lowered for digging. During initial and subsequent procurements, insufficient funds were available to purchase all of the ACEs required. The blade is hydraulic and can move on 3 axes: horizontal, vertical and diagonal. There are two more headlights at the front of the fender, near the cab. The ACE experienced trouble in reducing the berms associated with Iraqi tank ditches (berm on enemy side). Figure 4. For example, right front is half-full, left front is 3/4 full, rear is half-full, so that equals 250 remaining gallons. When a particular job requires a machine heavier than 37000 lbs (17000kg), the blade can be hydraulically lifted, and the scraper bowl can be filled with up to 9 tons of ballast bringing the vehicle weight up to 55000 lbs (25000kg). The vehicle is extremely compact in its design at 19 feet 3 inches (5.8 meters) long, 9 feet 7 inches (2.9 meters) wide, and 9 feet 1 inch (2.7 meters) high. Hydraulic filtration improvements - Hydraulic cleanliness is critical on the ACE. Maximum Trench Crossing: 62in (1.6m)

The ACE is a single operator vehicle,[3] without the moral and physical advantages of a crew with an NCO in charge, and without the advantage of a weapon for local suppression. This highlights the ACE's major shortcomings as a piece of mobility equipment used during direct fire engagements. Log in or register to write something here or to contact authors. Phase III & IV is under development. The vehicle hull is a welded and bolted aluminum structure with a two speed winch capable of 25,000 pound (110 kN) line pull. It was first fielded in 1986, and is capable of supporting forces in both offensive and defensive operations. Ground Contact Length: 105in (2.67m). The ACE proved to be a successful combination of armored vehicle and combat earthmover that was capable of keeping pace with the manoeuvre units, while providing crew survivability. The M9 ACE is a highly mobile, air-transportable, amphibious, fully tracked combat vehicle used primarily to prepare firing positions for tanks, artillery, and other weapons systems including other combat engineering vehicles such as the M728 CEV. A microclimatic cooling system is planned to be fielded FY 96. The driver's cupola is located at the rear of the vehicle, and can be completely sealed for combat operations and chemical or biological attacks. M109A6 Paladin fuel status in gallons.

Again, the objective is to transmit the correct on-hand amount of fuel, by platoon, to the company executive officer or command post. Whereas the M9 ACE was designed to operate in combat conditions, the M105 was not. SIP Phase 2 consists of: thicker roadarm retainers, preformed radiator hoses, lengthened oil drain line, redesigned parking brake linkage and steering rod, vent fan filter, tachometer/speedometer grease fittings, inclinometers, and steel CB/GS linkage. The blade is shallow and approximately track-width at 9 feet 7 inches (2.9 meters) across. Since the removal of swim missions as a task for the M9, the swim-related components are not required to be maintained. The M9 ACE System Improvement Plan (SIP) is a multi-phased program designed to improve the performance, durability, readiness and MANPRINT characteristics of the vehicle. It is used extensively for both offensive and defensive operations including dozing, scraping, grading, excavating, hauling, towing, and winching. The track is steel reinforced rubber. The reading is similar for the ABV chart (Figure 2). The inserts pull out, resulting in loose actuators, hull damage, hydraulic line failures and damage to roadarms and actuators.

The engine, drive train and driver's compartment are laid out in the rear of the vehicle, while the front features an 8.7 cubic yard (6.7 m³) bowl, apron and dozer blade. Your email address will not be published. The active Army has a total of 447 M9 ACEs. This will reduce frequency of track failures and make pin removal easier when track needs to be separated. The general consensus, however, is that they are a big improvement over, and are far more reliable than, the M9 ACE, although that troublesome vehicle is still in service after an upgrade program. This design was agreed upon and it was serialized as the M105. This high-mobility dozer emerged from the partnership between the Tank-Automotive and Armaments Command (TACOM) of Warren, Michigan, and the Defense and Federal Products department of the construction industry giant, Caterpillar Inc, based in Mossville, Illinois. Under this project, steel rings will be fastened inside the hull.

This will make it easier to get a socket on the nut even after the track edges get worn. This is an official U.S. Army Website sponsored by U.S. Army Maneuver Center of Excellence (MCoE). Your email address will not be published. This is heavier than the larger M9, but this is mostly due to the fact that the M9 was largely hollow. (The ABV is built on an M1A1 chassis.). Due to its intended use, the M9 was at least partially armored. As well as armed and armored vehicles, this need also translated to engineering vehicles. The M9 Armored Combat Earthmover (ACE) is a highly mobile armored tracked vehicle that provides combat engineer support to front-line forces. To achieve the cleanest possible hydraulic system, a more efficient return line filter and a high pressure filter at the compensating pump output will be added. Like many combat dozers, the blade allows the M105 to carve out hull-down positions for tanks, dig gun emplacements, perform route denial (creating and filling anti-tank ditches), improve bridge approaches, or even flatten ground to pave roads or airstrips. The book contains extensive color photos of the ACE in action in the field, and a comprehensive walkaround section for the detail-oriented. Road Wheels: 4 individually sprung per track
