Caterpillar MINI HYDRAULIC EXCAVATOR 303.5E - catalog of spare parts
Cat 303.5E CR provides high performance in a compact package that allows you to work in the most difficult conditions. Boom swing and auxiliary hydraulic functions are at your fingertips, ensuring smooth and easy handling. These controls, which are mounted on the joystick, provide better performance due to precise boom swinging and auxiliary functions. They also eliminate foot pedals and free the floor for more legroom for the operator. 100% pilot control ensures constant flow and pressure throughout the life of the machine. It also allows you to lock all controls when starting the machine and when the safety lock bar is in the up position.

-
The sliding door system provides good access and maintains the compact size of the machine, reducing the risk of damage.
COMPASS PANEL
Discover new features and experience the benefits of the COMPASS exclusive control panel on the new E-series excavators. The Caterpillar E-Series C-series E-Series mini-hydraulic excavator system has been completely developed for compact excavators. This adds several new features to the machines, increasing the cost of the client:
-
Standard anti-theft security system
-
Adjustable auxiliary flowmeter control for working tools
-
Continuous flow
-
Economy mode - fuel savings of up to 20% while maintaining high performance at the touch of a button.
STABILITY
All four models of the E series are characterized by increased stability while maintaining a compact radius. This increased stability results in greater productivity and versatility thanks to the use of heavier working tools and an extra long handle.
FAST, POWERFUL SHIP WITH HYDRAULIC SENSOR
High digging power and short cycle times provide the performance you need for your work. Load-sensing hydraulics optimize flow for smooth, powerful performance and increased fuel efficiency.
ENGINE
High-performance powertrain provides optimized engine power and high performance. The engine complies with US EPA Tier 4 Interim and EU Stage IIIA. Automatic engine idling automatically reduces engine speed when not in use, to save fuel and reduce noise and emissions to the environment. E-Series models are equipped with an engine shut-off switch that is conveniently located in the cab and is accessible from ground level.
AUTOMATIC TWO SPEEDS
Thanks to the standard automatic 2-speed function, the machine automatically balances the requirements for high speed and torque movement depending on the conditions in order to provide the operator with optimal speed and control. The car can be turned on in a low gear if a slower stroke is required in confined spaces.
ROTATION BUCKET 200 DEGREE
Industry-leading bucket rotation of more than 200 degrees provides greater material retention during loading. It also makes it easier to dig vertical walls without having to re-arrange the machine.
ZERO TAIL SWING
303.5E CR has a swing design with zero tail. On these models, the radius of the upper part of the body remains completely within the width of the chassis.
COUPLINGS
The E Series comes with a mechanical grip or hydraulic quick disconnect option. The design of the connector uses a wedge to hold the tool on the connector, reduce wear and maintain a tight fit throughout the life of the connector. The hydraulic coupling allows the operator to change tools without leaving the cab.
Wide range of working tools
A wide range of Cat working tools has been specifically designed for Cat mini excavators for maximum machine productivity. Available work tools include:
-
Buckets (heavy and heavy)
-
Tilt, Ditch Cleaning Buckets
-
Hydraulic Hammers
-
Augers
-
Thumbs up (not available in all regions)
-
Vibratory rollers
-
Quick coupling
STANDARD HEAD HEADS (HEAD IN EUROPE)
The machines come standard with brackets mounted on the handle and are ready to install a thumb hydraulic system for even greater machine versatility. A factory mounted bracket and safety valve make thumb installation easy and economical.
STANDARD AUXILIARY LINES AND BATTERY
Single-sided and double-sided auxiliary lines (combined function), including quick connections, are installed as standard equipment, so the machine is ready for operation. A standard battery allows you to relieve auxiliary pressure, making connecting and disconnecting working tools safer and easier.
Easy bulldozer control with the FLOAT feature
The function of the bulldozer is controlled by the pilot from the cockpit, ensuring smooth, proportional operation. The standard float function is activated by pushing the lever fully forward to the locked position. Cleaning and backfilling is easier because the operator does not need to adjust the height of the blade during movement.
EXCELLENT VISIBILITY OF BLADE
Blade visibility is excellent in any position, allowing the blade to be positioned behind the operator and away from the front linkage for better access when tightening the back and finishing in hard to reach places.
VARIANT OF ANGULAR BLADE
Increase machine versatility with the Cat dozer. Designed for strength and durability, the hydraulic corner knife has a wear-resistant edge made of hardened steel and good protection against cylinders and hydraulic lines. The corner knife can be positioned straight forward or at an angle of up to 25 degrees left or right. This reduces the number of times needed for backing up and moving backfilling so that you can complete your work faster. All blade functions are controlled by a single joystick using a proportional roller switch for the angle function.
RUBBER TRACK
The standard rubber track allows you to work on several surfaces, such as grass, pavement or stone, without damaging the surface or the machine.
OPTION STEEL ROAD
An optional steel track is available for tough conditions such as demolition. The extra weight of steel tracks usually provides better stability when digging on the side of the machine.
RUBBER PILLOWS
Additional rubber gaskets can be attached to the steel rail to prevent damage to paved surfaces and to minimize noise and vibration during movement using a steel rail system. This option provides maximum overall stability.
EASY SERVICE
Convenient service functions simplify maintenance and reduce downtime:
-
The lift side cover provides access to the air filter, the main body valve, the 1-way / 2-way auxiliary flow selector, the accumulator, the fuel filter and the hydraulic reservoir. This eliminates the need to raise the cab when servicing and maintaining the machine.
-
A hinged rear door provides access to major components and service points, including checking and filling up engine oil, a vertically mounted engine oil filter, a starter motor and a generator.
-
Easy access to the radiator and the oil cooler simplifies cleaning and reduces maintenance time.
-
The SOSSM sampling valve allows easy removal of hydraulic fluid for preventative maintenance.
-
500 hours of changing the engine oil and filter reduces maintenance and downtime.
