The Cat® 3306 uses direct injection to control fuel consumption and allows lower engine speeds for reduced stresses and increased life.
3306 Diesel EngineThe Caterpillar® 3306 is a six-cylinder, four stroke diesel. The large displacement allows lower engine speeds for reduced stresses and increased engine life.
Direct InjectionThe 3306 maintains good productivity per unit of fuel burned by using direct injection to control fuel consumption. Optimum weight-to-horsepower ratios minimize cycle times, allow larger blade loads and shorter load times.Injector nozzels are non-clogging and adjustment free.
Aluminum PistonsThe 3306 features cam-ground three-ring cast tapered aluminum alloy pistons used to reduce friction, decrease heat build-up and provide excellent oil control. Crankcase journals are hardened and aluminum bearings are steel-backed. The high fatigue aluminum alloy-bearings surface not only has the capability to withstand heavy shock loads during crankshaft rotation, it will also adapt to normal wear of the crankshaft journals.
ValvesValves are stellite face hardned with hard alloy steel seats for hardness that contributes to long service life.
RebuildabilityThe 3306 has the ability to be rebuilt to provide long and reliable life.
With a power train that is designed and built by Caterpillar, the D6G Series 2 XL ensures compatibility, maximum performance and reliability.
Torque DividerThe torque divider arrangement is a Caterpillar exclusive that provides high torque multiplication when under load with direct drive efficiency when completing lower engine load functions such as backfilling trenches or spreading material.
Power Shift Transmission
Three speeds forward and three speeds reverse, utilizing large diameter, high capacity, oil-cooled clutches.
- Modulation system permits fast speed and direction changes.
- Oil-to-water cooler for maximum cooling capacity.
- Forced oil flow lubricates and cools clutch packs to provide maximum clutch life.
The Caterpillar undercarriage is designed for optimized machine balance and best possible performance and component life.
Roller FramesThe track roller frame is a reinforced box section construction with seven lifetime lubricated track rollers per side and outside mounted carrier rollers, two per side.
Rollers and IdlersFeature symmetric Duo-Cone seals for long sealing life to prevent oil loss and dirt entry. Toric rings maintain performance over a wide range of temperatures. Rollers and idlers are lifetime lubricated, serviceable and rebuildable to provide value. Abutment-style caps securely attach rollers and idlers to the bogies.All idlers, track and carrier rollers are life-time lubricated and require no periodic maintenance intervals.
Track ShoesTrack shoes are available in sizes to match the working conditions.
GuardsFront and rear guiding guards are standard.
Sealed and Lubricated TrackMinimizes internal bushing wear with the pin by a thin film of lubricant and retained by a polyurethane seal. Extends service life of the undercarriage as a system.
The operator station is designed with optimum comfort and maximum productivity in mind.
Directional ControlsSteering and transmission controls are located conveniently to the operator's left for comfortable operation.
Dozer Blade ControlsThe dozer controls are located on the operator's right hand side.
Walk Through Operator AreaThe operator area has a walk through design providing a comfortable operating environment with the controls within easy reach.
SeatA comfortable suspension seat is able to be adjusted fore and aft for greater operator comfort. Arm rests also help provide comfort for all day operation. Wide 76 mm (3 in) seat belt is standard.
A machine monitoring system lets you track the following machine systems:
- Fuel level
- Coolant temperature
- Transmission/torque converter temperature
- Service hour meter
- Air cleaner service indicator
- Engine oil pressure and alternator are monitored by a warning lamp and audible alarm system.
Brake PedalA single brake pedal actuates both tracks to make operation easier.
Air ConditionerAn optional air conditioner with strategic vents provide a comfortable environment in a variety of weather conditions.
CabThe optional cab is pressurized to keep dust out. A 3 speed blower fan is standard.
Work Tools and Ground Engaging Tools provide the flexibility to match the machine to the job, maximizing performance.
BulldozersAll blades feature a strongbox-section design that resists twisting and cracking. Blades are made of Cat DH-2™ steel that has high tensile strength and stands up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
Straight BladeThe straight blade can handle a wide variety of materials including heavy material. With the high kW per mater (HP/ft) of cutting edge, aggressive penetration is achieved.
Angle BladeThe angle blade can be positioned straight or angled 25 degrees to either side making this blade a versatile option.
Semi-Universal BladeThe Semi-Universal blade is built for tough applications where penetration is more important than capacity. The blade wings are designed for superior load retention and penetration in tightly packed materials and for finishing applications.
Multi-Shank RipperMulti-shank rippers are made to penetrate tough material fast and rip thoroughly for use in a variety of materials.
Cutting Edges and End BitsCutting edges are made of DH-2 steel. End bits are made of DH-3™ steel to provide maximum service life in tough materials.
Serviceability and Total Customer Support
The most serviceable machines from the most committed dealers. World-class product support. The Cat Dealer Network trained experts keep your fleet up and running, maximizing your equipment investments.
ServiceablityMinimizes maintenance and repair downtime. Large openings on either side of the machine make major service points easily accessible.
Machine SelectionMake detailed comparisons of the machines you are considering before you buy. How long do components last? What is the cost of preventive maintenance? What is the true cost of lost production? Your Cat Dealer can give you answers to these very important questions.
PurchaseConsider the financing options available as well as day-to-day operating costs. This is also the time to look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long run.
Product SupportPlan for effective maintenance before buying equipment. Choose from your dealer’s wide range of maintenance services at the time you purchase your machine. Programs such as Custom Track Service (CTS), S•O•S analysis, Technical Analysis and guaranteed maintenance contracts give peak life and performance to your machine.
Parts ProgramYou will find nearly all parts at your dealer parts counter. Cat Dealers use a world-wide computer network to find in-stock parts to minimize machine downtime.Ask about your Cat Dealer’s exchange program for major components. This can shorten repair time and lower costs.
Remanufactured ComponentsGenuine Cat Remanufactured parts save you money. You receive the same warranty and reliability as new products at cost savings to further reduce operating costs. Components are available for the drive train, engine, and hydraulics.
OperationImproving operating techniques can boost your profits. Your Cat Dealer has training videotapes, literature, and other ideas to help you increase productivity.
