Caterpillar TRACK-TYPE TRACTOR D7R II - catalog of spare parts
D7R is long-term value and durability. From robust designs to fully integrated engine and powertrain systems - the D7R is a world-class tractor designed to help you perform the highest quality work in a wide variety of areas. The Cat`s unique torque divider transmits 70 percent of the engine`s torque through a converter and 30 percent through a direct drive shaft to increase transmission efficiency and increase torque. The planetary power shift transmission includes three forward speeds and three reverse speeds, with thick large-diameter clutches, high throughput and oil cooling. These clutches provide higher torque and longer life.

COMFORT AND CONTROL
Insulated sealed cab reduces noise and vibration.
Large single-pane windows provide excellent visibility throughout the machine for increased productivity and safety.
The seat of the Comfort Series is offset by 15 degrees for better visibility.
Adjustable seats and armrests provide comfort when working on steep inclines or slopes.
The display is easy to read, even in direct sunlight.
Ergonomic controls for easy and effortless control.
The retarder pedal provides full control of the engine speed when the toggle switch is in the high idle position.
One-handed control performs steering and gear selection.
Tiller bar control allows the operator to work more accurately in tight areas around structures, stakes and other machines.
Differential control provides the best modulation in the industry.
PRODUCTIVITY AND PERFORMANCE
Precise controls optimize power and fuel efficiency.
Differential steering maintains power on both tracks when turning. When one track accelerates, the other slows down equally. Improved maneuverability, especially with large loads on the blades, as well as increased cycle time.
The modular transmission and differential are inserted into the rear case for ease of maintenance, even if a ripper is installed.
CREATED FOR LONG-TERM PRODUCTION
Durable frame absorbs shock and shock loads.
The hinge shaft of the bulldozer passes through the main frame and connects the roller frame for independent oscillation.
A fixed equalizer frame allows rollers to swing up and down to better fit the contours of the soil for maximum grip and operator comfort.
Tag-Link design sets the blade closer to the machine for superior maneuverability, balance of the machine and blade penetration.
The raised sprocket design optimizes the balance of the machine for best performance in every application. In addition, it keeps the center of gravity of the machine low, providing excellent stability, balance and cravings.
Impact loads on the ground and attachments are transmitted to the base frame to protect the main gears, axles and steering components from sharp shocks and extend their service life.
Modular powertrain components allow you to quickly remove and repair the transmission, final drive, steering differential or brakes.
Modular suspension components simplify maintenance. Life-long lubricated loafers and tracked / supported rollers provide the ability to reuse internal components and rebuild or re-assemble components, reducing the cost of owning and operating, as well as raw materials and natural resources.
TOP TIER SERVICE AND SUPPORT
Modular components, easy access to regular service points and functions that provide faster diagnostics, all this reduces maintenance time and more time to work.
Cat machines are equipped with openings for sampling engine oil, power transmission hydraulics and coolant.
The main components of the D7R are assembled for restoration, which extends the life of the machine. Reconstruction saves money and supports sustainability, saving raw materials and natural resources.
Manage costs with preventative maintenance programs such as the Custom Track Service, S · O · SSM analysis, and guaranteed service contracts. Stay productive with best-in-class parts.
When it`s time to replace, your Cat dealer can help you with original Cat remanufactured parts. Refurbished powertrains and hydraulic components are cheaper, but they have the same warranty and reliability as new products.
EQUIPPED FOR WORK
The Landfill Arrangement Manipulator offers special fencing, impact plates and seals that help protect the machine from shocks and airborne / wrapping debris. Cooling is designed for environments with a high content of debris and easy cleaning. Special air treatment functions help deliver clean air to the machine. Blades for landfill and center-hole crawler shoes help optimize the performance of your waste management facility.
The Cold Weather kit is equipped with a reversible fan and a battery / generator for cold start. The Arctic cabin has double glass. Oils and seals main gear designed to work in cold conditions.
The location of the warehouse helps to protect the machine and the operator in conditions of heavy pollution. Equipped with a preliminary turbine cleaner, one-piece casing and cooling system designed to reduce clogging and facilitate cleaning.
