Engine

Proven Cat engines provide the power and torque rise for excellent lugging in tough loading conditions.

Fuel System

The fuel system and Electronic Control Module on the 3408E tractor engine economically and precisely deliver fuel.

Injection Pressures

High injection pressures, independent of engine speed, decrease smoke and emissions while improving response.

Variable Injection Timing

Variable injection timing and duration improve fuel efficiency and cold starting, decrease smoke and emissions.

Injection Rate Shaping

Injection rate shaping reduces emission and engine noise.

Mechanical Parts

Fewer mechanical parts in the fuel system improves reliability.

Electronic Control

Electronic control provides automatic altitude deration and automatic air filter restriction deration.

Multiple Horsepower Ratings

Multiple horsepower ratings limit output in first and second gears unless the operator has the auger or elevator engaged.

Neutral Start Control

Neutral start control prevents engine from starting unless transmission is in neutral.

Throttle Back-up

Throttle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.

Directional Shift Management

Directional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.

Controlled Throttle Shifting

Controlled throttle shifting increases drivetrain life by reducing the fuel injection rate just prior to shifting.

Automatic Ether Starting Aid

Automatic ether starting aid greatly improves cold weather starting.

Electronic Ground Level Shutoff

Electronic ground level shutoff enables the operator to stop the engine from the ground with the flip of a switch.

Steel Spacer Plate

Steel spacer plate between the block and head eliminates the need for counterbores and helps prevent associated cracking problems.

Oil-Cooled Pistons

Oil-cooled pistons and full-length water-cooled cylinder liners provide maximum heat transfer for longer component life.

Aftercooler

The aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.

Engine Oil Cooler

Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.

Laminated Thermo-Shield

Laminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.

Optional Retarder

The optional retarder can extend brake life.

Transmission

Eight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.

Neutral Coast Inhibitor Control

Neutral coast inhibitor control helps prevent the transmission from shifting to neutral at speeds above 8.1 km/h (5 mph).

Top Gear Control

Top gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.

Electronic Programmable Transmission Control (EPTC II)

Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.

Electronically Controlled Cushion Hitch

Smoother ride improves productivity.

Design

The Caterpillar electronically controlled cushion hitch design dampens shocks to provide a smoother ride.

Nitrogen Accumulators

Nitrogen-over-oil accumulators absorb and dampen road shocks.

Cushion Hitch Lock

Electronically controlled cushion hitch locks down for positive control of the cutting edge during loading and dumping.

Double Kingbolt Design

Double kingbolt design withstands high external forces and allows easy installation and removal.

Hitch Castings

Extensive use of steel castings eliminates many welded joints, making a strong hitch.

Scraper Bowl

Low, wide, large-capacity design boosts production.

Edge

Wide cutting edge scoops large volume loads from shallow cuts, while the low-profile design of the bowl offers less resistance to incoming materials.

Construction

Cellular construction adds strength and dent resistance to bowl sides and floor.

Steel Router

Steel router and edge supports, floor plates and high-abuse components are tempered for strength.

Bulldozer Ejection system

Cat bulldozer ejection system combines constant spreading control with bowl-cleaning efficiency.

Two-Stage Ejection System

The 633E II is equipped with the two-stage ejection system. The floor slides back as the ejector moves forward. Actuated by smooth, double-acting hydraulics.

Angled Top Plate

Angled top plate on ejector helps retain load.

Variable-Speed Elevator

The infinitely variable-speed elevator matches loading speed to material - from high speed for normal or loose conditions to low speed for tough materials.

Operator's Station

Comfort and control increase operator efficiency.

Cab

Standard rubber-mounted cab reduces noise and vibration for comfortable, shift-long operation.

Controls

Low-effort controls are easily accessible for sure, precise operation.

Steering

Hydraulic servo-steering system provides low-effort automotive feel and excellent maneuverability.

Diagnostic Connector

Diagnostic connector, with the aid of a service tool, allows quick analysis of the starting and charging circuits.

O-Ring Face Seals

O-ring face seals help keep these machines 'dry'.

Centralized Lubrication Blocks

Centralized lubrication blocks for the hitch and steering reduce lube time.

Service Points

Service points for the engine are grouped on the right side for easy access.
