CB 334 D Caterpillar CB 334 D Specifications & Technical Data (2000—2004)

Caterpillar® 3013 and 3014 Engines

Precise balance and optimum running speed for smooth operation and extended engine life. Engines are liquid-cooled, keeping temperature low and helping reduce component wear. The timing drive uses three helically cut gears that help reduce noise levels. A heat-treated chrome molybdenum steel crankshaft provides durable service life.

Vibratory System

Pod-style weight housings are assembled and sealed at the factory to ensure cleanliness, extended bearing life and easy field exchange/service. Change interval for bearing lubrication is every three years or 3000 hours. Balance between frequency and amplitude provides a good mat finish for commercial work. High frequency on CB-334D produces 68 Hz. This is the highest in its size class.

Value Analysis

Versatile Operation High-frequency vibratory system on CB-334D. CB-335D rubber tires make it effective on both asphalt and soil. Productivity Responsive diesel power. High travel speeds. Nearly equal front-rear weight distribution. Easy Control Single lever control of forward/reverse speeds. Low-effort steering. Excellent visibility. Simplified Maintenance Simple, durable design. Rugged construction for extended service life. Easy access to all major components.

Excellent Forward and Rearward Visibility

Excellent forward visibility allows the operator to see objects 0.6 m high and 1 m in front of the machine. Rearward visibility is even better, as the operator can see objects that are 0.8 m behind the machine and flush to the surface. The sloped engine enclosure and low-profile rear end provide unobstructed sight lines to ground personnel working near the machine.

Water Spray System

Constant or intermittent spray capabilities provide extended operation between refills. Polyethylene water tank capacity is 300 liters. When using the intermittent spray mode, an operator can expect to fill the tank only twice during an eight hour shift on the CB-334D and only once with the CB-335D. Triple water filtration reduces machine downtime caused by system clogs. Extended-life water pump provides optimum spray and flow. Water pump and filters are conveniently located for easy access. Large water tank drain allows system to be drained in less than five minutes. Additionally, spray bars are constructed of stainless steel for corrosion resistance. The water tank is reinforced polyethylene. An electric water pump provides either continuous or intermittent spray, with the intermittent spray setting increasing spray time by 50% over the continuous setting. Triple filtration includes a filter on the tank fill spout, an in-line filter at the water pump, and filters on each spray nozzle. Spray nozzles are easily removed without tools for cleaning.

Electrical System

The 12-volt electrical system includes one maintenance-free Cat battery and color-coded and numbered wiring wrapped in nylon braid. The system includes a 55-amp alternator. The starting system provides 750 cold cranking amps.

Tire Wetting System

CB-335D – option Tire Wetting System allows a solvent to be sprayed on the tire surfaces, helping prevent asphalt from adhering to the tires. One spray nozzle is positioned above each tire. The system is controlled with a momentary switch on the control console.

Drum Design Keeps Production High

Tapered-bevel drum edges help eliminate marks on deep lifts or when turning. Drums are constructed of rolled steel plate and are finished to reduce surface irregularities. Replaceable rubber mounts isolate vibration and enhance vibratory capabilities. Each drum is fitted with two adjustable, spring-applied scrapers, positioned at the front and rear of each drum.

Transmission

CB-334D – Variable-displacement piston pump supplies pressure flow to fixed-displacement hydraulic motors that drive the front and rear drums. CB-335D – Variable-displacement piston pump supplies pressure flow to a fixed-displacement hydraulic motor that drives the front drum, and the pump supplies pressure flow to two fixed-displacement motors that drive the rear wheels. For both machines, a propel lever located at the operator’s station provides smooth hydrostatic control of the infinitely variable speeds in both forward and reverse.

Wheels and Tires

CB-335D – 7.50 x 16 6-ply tires are standard. Each tire is equipped with a replaceable scraper. The scrapers help clean asphalt or soil off the tires. The scrapers can be positioned above the tires when they are not needed. Wheels are on a fixed axle.

Operator Comfort

Single-lever control provides simplified operation, making the machines a perfect fit for inexperienced operators. Easy-to-understand instrument panel allows the operator to quickly verify the status of machine systems. Lockable cover protects instrumentation and gauges. Low sound levels make them comfortable for both operators and spectators. Isolated operator’s station with four rubber mounts helps eliminate vibration before it reaches the operator, controls and instrumentation.

Instrumentation

The control console includes: steering wheel; engine throttle; water spray system switch; vibratory system switch; vibratory drum selector switch; hour meter; horn; fuel gauge; start switch; heat start switch; parking brake; and four-segment light for hydraulic oil temperature, oil pressure, alternator, and engine coolant. The control console is protected with a lockable cover.

Frame

Frame is fabricated from heavy gauge steel plate and joined at the center articulation pivot by a single-piece hitch. Oscillating stops provide ±9° frame oscillation. The articulation angle is ±35°. Additionally, the articulation pivot is structurally reinforced for extended service life, and the special bearing material in the articulation hitch never needs to be greased.
