Caterpillar D5B Dozer
#1
Heritage and Manufacturing Context
The Caterpillar D5 lineage stretches back to 1939, with the reintroduction of the D5B model in 1977. This machine evolved from earlier versions and was built to combine durability and manageable power. The D5B typically housed a 201 cubic inch (3.3 L) six-cylinder diesel engine—later referred to as the 3306—with a power output of about 105 horsepower (78 kW) . Production continued into the mid-1980s, with many units manufactured by Caterpillar–Mitsubishi and distributed globally .
Specifications and Mechanical Traits
Here are its key characteristics, presented clearly and compactly:
  • Operating Weight: Approximately 20,400 to 25,800 pounds (9,265–11,700 kg)
  • Blade Width: Around 10.4 feet (3 m), ideal for efficient material moving
  • Dimensions:
    • Length with blade: ~15.1 ft (4.6 m)
    • Width over tracks: ~7.75 ft (2.36 m)
    • Height at cab/top: ~9.09 ft (2.77 m)
  • Fuel and Hydraulics:
    • Fuel capacity: ~65 gallons (246 L)
    • Hydraulic system: 13 gallons, operating at ~2,250 psi (155 bar), with ~43 gpm (163 L/min) pump flow
  • Transmission: Offered in both a five-speed direct drive and a three-speed powershift to suit different operator preferences
These features illustrate a machine that balances manageable weight with respectable power and efficiency.
Strengths and Field Impressions
Operators recall the D5B as a stable and capable dozer, especially suited for tasks such as land clearing, secondary bush operations, and light farm work. One user reminisced about clearing dense pine and scrub growth, noting the D5B’s robustness and consistent performance even in challenging ground conditions .
Another veteran shared, “With a heavy cultivator on wet ground, traction becomes critical—especially when using narrow 16-inch tracks, which tend to sink under pressure. That’s where you need to manage your gear selection carefully to preserve mobility” .
These anecdotes highlight how the D5B excelled in real-world, demanding environments—offering reliability and ruggedness in compact form.
Weaknesses and Maintenance Considerations
A recurring issue noted by operators involves the final drives. These mechanical components often showed wear signs, and early inspection is advised. Draining and examining the oil in the final drives for metal shavings or discoloration is considered essential preventive maintenance . Addressing this early can prevent costly failures later on.
Another operator emphasized the lack of engine braking in powershift variants—meaning operators must rely heavily on standard braking systems on steep grades .
Practical Data Summary
  • Operating weight: 20,400–25,800 lbs
  • Engine: ~105 hp, Caterpillar 3306 diesel
  • Blade width: ~10.4 ft
  • Fuel capacity: ~65 gallons
  • Hydraulic capacity: ~13 gallons
  • Transmission: Direct drive or powershift
  • Compact dimensions make it easily transportable
Field Stories and Reliability
One memorable adventure involved a D5B configured with a wide track and rake attachment, operating relentlessly in South Florida’s sandy muck, clearing acres of plantation terrain. The operator estimated clearing about 4 acres a day—an impressive feat that speaks volumes about the machine’s endurance and adaptability .
Recommendations for Operators
  • Inspect final drives regularly, checking oil for metal and signs of wear.
  • Match track width to ground conditions—wide tracks help prevent sinking in soft soil.
  • Be aware of transmission capabilities—powershift units lack engine braking; plan operations accordingly.
  • Maintain hydraulic and fuel systems consistently, and ensure the undercarriage remains clean and tensioned properly.
Summary
The Caterpillar D5B bulldozer shines as a compact, straightforward, and effective crawler—offering a reliable 105 hp powerplant, durable transmission options, and a versatile blade, wrapped in transport-friendly dimensions. Built in the late 1970s and '80s, it serves as a testament to Caterpillar’s engineering philosophy: rugged dependability in a manageable footprint. While final-drive issues and transmission-specific traits merit attention, a well-maintained D5B continues to act as a trusted companion in rough terrain and demanding tasks.
