Caterpillar TRACK TYPE TRACTORS D7R - catalog of spare parts
Caterpillar has been a world leader in tracked tractors for over a century. D7R delivers Cat`s legendary durability and reliability through proven technology designed to increase your productivity and profits. From robust construction to fully integrated engine and powertrain systems, the D7R is a world-class tractor designed to help you perform the highest quality jobs in the challenging conditions that are observed when filling land around the world. Protective covers of the last drive prevent the winding of wire, nylon ribbons, etc. And damage to Duo-Cone seals. The outer casing is now stationary, thicker and has increased hardness, which helps prevent excessive wear from debris. This design provides excellent seal protection. The garbage had to make four turns through 90 °, penetrate through the packaging material, and then make two more turns through 90 °.

RADIATOR Guard
Reliable hinged protection radiator protects the cooling system.
RESTRICTED (BELLY) PROTECTION
Protection crankcase (abdomen) serves a dual purpose. They help prevent contact damage to vital powertrain components and help prevent debris from entering the powertrain compartments.
PROTECTION OF CYLINDER TILT LINES
Tilt cylinder guards help protect hydraulic lines from damage to the contacts, while maintaining hose flexibility.
LIMITATIONS OF GROSS SHAFT MANAGEMENT
Swivel shaft guards help prevent debris from entering and damage to Duo-Cone ™ seals, as well as protect bolts on the swivel shaft seal holders.
IDLER SEAL GUARDS
Tension ring guards prevent wire, line, strapping, etc., from winding. And damage to Duo-Cone seals.
CHASSIS Guards
Chassis guards help protect the engine compartment by deflecting debris from lifting up along the chassis.
HIGH-PRECISE ALTERNATOR
The powerful alternator provides the extra power needed for electrical accessories such as extra lighting, radio communications and entertainment radios. There is an air duct that helps prevent debris from entering the generator.
CAT® TURBINE AIR PRECLEANER
The Cat turbine provides improved air filtration in the engine using an OPTIMAX two-stage pre-filter set in motion by intake and exhaust air flow. The intake air is rotated by the flow-driven impeller. Garbage is stratified along the outer wall and discarded back into the environment. The remaining impurities are collected and removed by the secondary cleaning system, which allows only purified air to enter the engine air filter.
HEAVY STEPS AND HANDLES
Heavy duty steps and handles are made of sheet steel and solid rods to withstand harsh working conditions in a landfill.
REAR STRIKER BARS
The rear clips have a hard drawbar and a body with large doors for storage on machines that are not equipped with rippers. The rear rear plates are ready to counterbalance in case additional rear weight is required.
FRONT STICKER BARS
The angled design of the front slats prevents debris from entering the track and damaging the wings or fuel and hydraulic tanks.
Security guard
The protective cover has a non-rotating protective cover mounted above the final drives to prevent the wire from winding. The guard includes inspection plates.
Ejector fan
The ejector fan has twisted training edges, which radially deflect debris from the cores of the radiator to reduce the likelihood of clogging of the cores of the radiator.
WHEELS LANDFILL BLADES
Cat Landfill blades increase the amount of dosing and help prevent material from entering through the blade into the radiator.
LAMINATED HEAT SHIELDS
Multi-layer heat shields cover the exhaust pipe inside the compartment, the hot side of the turbocharger, and the exhaust manifold. These screens reduce the surface temperature well below the flash point of most combustible materials encountered. Cat Waste Disposers are equipped with water cooled turbochargers to further reduce surface temperature.
CONDENSER AND AIR CONDITIONING FANS WITH CONSTRUCTOR
The air conditioner and fans installed on the ROPS are moved from the engine compartment to the ROPS. • Moving the condenser and fans away from the radiator reduces debris concentration and clogging. This movement also increases the cooling capacity of the machine to operate at higher temperatures.
PROTECTION OF HYDRAULIC AND FUEL TANKS
Hydraulic and fuel protection helps protect the unit`s hydraulic oil tank, battery compartment and fuel tank.
TRASH RESISTANT RADIATOR
Cat tracked tractors are equipped with rubbish-resistant radiators that have a longer gap between the core ribs to prevent clogging of the radiator.
COMPLETE GROUNDING SYSTEM (CAES)
The computer-aided earthmoving system (CAES) is a high-tech tool for waste disposal, which provides maximum compaction, denser slopes and slopes, and also retains valuable surface soil without stakes and brigades, which increases safety on site. By controlling the compaction process and control of the slope, operators receive the information they need to maximize the efficiency of the machine, which leads to proper drainage and optimal airspace. This advanced technological tool also helps in identifying storage areas for specific objects that require special handling and placement records, such as hazardous, middle, silt and industrial materials. Using Global Navigation Satellite System (GNSS) technology, car-mounted components, a high-speed radio network, and office management software, this system delivers information to the display in the cab, which helps improve productivity and efficiency in the field. Note. Contact your Cat dealer for more information about CAES in the area of waste disposal and authorization / licensing compatibility in your area.
PERFORMANCE
Cat machines are designed for ease of maintenance. Modular components, easy access to regular service points and functions that provide faster diagnostics, all this reduces maintenance time and more time to work.
DIAGNOSTIC CONNECTOR
The diagnostic connector allows Cat electronic test equipment to quickly troubleshoot access to any stored data using an Electronic Technician (Cat ET).
ENVIRONMENTAL DRAINAGE
Ecological wastewaters provide an environmentally friendly way to drain fluids. These are recommended items that are included in the radiator, hydraulic tank and main power train components.
Grouped service points
Grouped service points and easy access to service areas make routine checks quick and convenient.
ANALYSIS OF GRAPHIC SAMPLE OF OIL (S · O · SSM)
Monitor machine condition and determine basic maintenance needs before they result in downtime due to routine Cat sampling. Cat machines are equipped with openings for sampling engine oil, power transmission hydraulics and coolant. Cat oil sampling provides accurate analysis using tests developed by Caterpillar for Cat products, as well as qualified interpretation of results.
CREATED TO BE RECEIVED
The main components of Cat tracked tractors are designed to be rebuilt, extending the life of the machine. Re-equipment of machines and components saves money and provides an element of sustainability by saving raw materials and natural resources. Contact your Cat dealer to learn more about recovery options.
FULL CUSTOMER SUPPORT
Only Cat machines come with industry-leading sales and service support — the Cat dealer network. From helping you choose the right equipment to ongoing support, your Cat dealer will provide you with the best sales and service.
