| Net Power - ISO 9249/SAE J1349 | 363 hp | 271 kW | Caterpillar D8 — Engine. Net power at 2,050 rpm. Net power advertised is the power available at the engine flywheel when the engine is equipped with a fan, air cleaner, clean emissions module and alternator. Advertised power is tested per the specified standard in effect at the time of manufacture. Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. * Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).

What the specifications mean
The published D8 values remain attached to their stated configuration and rating basis.
D8 standard undercarriage, SU blade straight; single-shank ripper fitted, tip on ground. Width across End bits.
An individual machine must be verified by serial/PIN, installed equipment and actual measurements.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used D8 inspection priorities
- Obtain measured undercarriage percentages and matched-component history.
- Inspect blade linkage, push arms or C-frame, equalizer bar and pivot points.
- Test steering, transmission and installed grade-control hardware under load.
- Match the D8 model plate, fitted attachment and undercarriage to the cited reference configuration.
Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.
Hours, condition and ownership cost
Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.
Cost drivers to model
- Undercarriage life depends on material, slope, travel and turning practices.
- Blade edges, rear equipment, final drives and cooling need separate reserves.
- Technology value depends on installed, licensed and calibrated hardware.

Attachment considerations
Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
Implements are treated as configurations for this machine class. Blade, ripper, winch and rear-equipment details must be verified on the actual dozer.
Before confirming fitment
- generation and machine configuration
- mounting interface, coupler or pin geometry
- hydraulic flow, pressure, return and case drain
- attachment weight and machine capacity limits
- electrical controls or required machine options
Model-reference transport profile
Transport reference
Reference measurements retain their configuration and verification status. Confirm the actual transport setup before booking.
Reference specifications can differ from the actual configured machine. Confirm dimensions and weight before booking transportation.
Confirm or replace before a transport request
- actual weight
- actual travel length, width and height
- attachments and removable work tools
- bucket, blade, carriage or boom position
- loading condition
