Overhaul

MHIL manufactures, rebuilds, and overhauls complete 125 mm main-gun assemblies and their precision subsystems to restore barrel-line accuracy, safety, and battlefield readiness. Our MRO scope covers structural gun cradles, machined breech blocks and breech rings, safeguard plates, elevating gearboxes, thermal sleeves, and recuperator units—each restored through dimensional inspection, non-destructive testing, and fitment to original equipment specifications. From worn rifling interfaces to fatigued recoil components, every part is returned to service with traceable workmanship suited to sustained main battle tank operations.

Gun laying accuracy depends on reliable electro-mechanical control chains, and MHIL overhauls the full suite of gun-control electronics and actuators that keep turret weapon systems on target. We rebuild vertical drive units, protection modules, PT-800 regulators, memory units, gun control units, joysticks, starting distributors, transistor drivers, angle limiters, ammunition selectors, and gunner control panels. Each assembly undergoes functional bench testing, connector refurbishment, and calibration against platform interfaces so that elevation, traverse, and fire solution inputs respond with the precision expected in combat conditions.

Crew situational awareness relies on rugged optical paths and stabilised optronics, and MHIL rebuilds both the mechanical sighting hardware and the electronic boards that keep images steady under motion. Our MRO portfolio includes commander vision blocks, driver and gunner periscopes, gyroscope power boards, image-stabilising circuits, laser power modules, common power boards, amplifying assemblies, and embedded logic units. Lenses, seals, and PCB assemblies are refurbished to eliminate moisture ingress, drift, and signal loss—returning day-and-night targeting clarity to armoured fighting vehicles operating in the harshest field environments.

Mobility and ride quality are rebuilt from the ground up through comprehensive running-gear and suspension MRO. MHIL restores roller assemblies, torsion bars, road wheels, drive sprockets, rubber track pads, complete track links, impeller fans, and engine radiators that absorb the punishing loads of cross-country armoured operations. Worn bearings, fatigued suspension elements, and heat-exchanger cores are refurbished or replaced to OEM geometry, returning reliable traction, cooling performance, and crew comfort over long operational cycles.

Fighting effectiveness depends on stable onboard environments, and MHIL services the environmental-control assemblies that regulate temperature and airflow inside sealed armoured hulls. We overhaul control boxes, inner heat-exchanger units, external louvred condenser modules, heater assemblies, bent piping runs, mounting straps, hose clamps, gaskets, and filtration screens. Systems are leak-tested, electrically verified, and refitted to restore crew comfort, electronics cooling, and reliable operation across extreme desert and high-altitude deployments.

Crew effectiveness and field sustainment are supported through overhaul of human-factor and maintenance equipment that keeps armour operating in remote conditions. MHIL rebuilds gunner and driver seating assemblies with harnesses and mounting frames, high-capacity filtration units, fuel refilling pump sets with hoses, and torque-multiplier track adjustment toolkits. Each item is restored for ergonomic safety, structural integrity, and repeatable maintenance procedures—ensuring crews remain secure, supplied, and equipped to keep platforms mission-capable between overhauls.
