1. Core Power & Powertrain (Engine)
The 1985 D7G is powered by the legendary CAT 3306 engine. This engine is highly coveted in global export markets due to its mechanical simplicity, robust torque, and high tolerance for varying diesel quality.
| Parameter | Metric System | Imperial System | Technical Remarks |
| Engine Model | CAT 3306 | CAT 3306 | Inline 6-cylinder, Turbocharged |
| Net Flywheel Power | 149 kW | 200 hp | Rated @ 2000 rpm (ISO 9249) |
| Displacement | 10.5 L | 641 cu in | Optimized for high-torque heavy-duty work |
| Cooling System | Pressurized | Pressurized | Heavy-duty tropicalized radiator |
2. Weight, Capacities & Logistics Dimensions
These specifications are critical for international freight forwarders, particularly for calculating costs for RORO (Roll-On/Roll-Off) or break-bulk shipping.
| Parameter | Metric System | Imperial System | Shipping & Logistics Relevance |
| Operating Weight | 22,300 kg | 49,160 lbs | Standard configuration (ROPS + Blade) |
| Transport Length | 5,200 mm | 17.06 ft | Blade removed for specialized freight |
| Transport Width | 2,800 mm | 9.19 ft | Standard width for heavy-haul road permits |
| Transport Height | 3,300 mm | 10.83 ft | Top of ROPS/Cab clearance line |
| Fuel Tank Capacity | 415 L | 109.6 gal | Extended site autonomy for remote operations |
3. Blade & Hydraulic Performance
The D7G utilizes a direct-acting, mechanical hydraulic control system. This “old-school” architecture is preferred by international operators for its reliability and ease of field repair.
| Parameter | Metric System | Imperial System | Field Performance Indicator |
| Blade Type | Semi-U / Straight | Semi-U / Straight | Application-specific variable options |
| Standard Blade Cap. | 5.2 m³ | 6.8 yd³ | High-capacity earthmoving geometry |
| Hydraulic Pressure | 18,600 kPa | 2,700 psi | Main implement relief circuit threshold |
| Max Lift Height | 1,200 mm | 3.94 ft | Optimized clearance for heavy debris |
4. Undercarriage & Drivetrain
Built on a high-strength steel mainframe, the D7G features a proven planetary power-shift transmission, ideal for the high-impact environments of mining and large-scale clearing.
| Parameter | Metric System | Imperial System | Underfoot Mobility |
| Transmission Type | Power-Shift | Power-Shift | 3 Forward / 3 Reverse gears |
| Track Shoe Width | 560 mm | 22 in | Standard extreme-service grouser profile |
| Track Gauge | 1,980 mm | 6.50 ft | Stability-optimized base for side-slopes |
| Max Travel Speed | 9.5 km/h | 5.9 mph | Rapid site-to-site transit speed |
| Max Drawbar Pull | 280 kN | 62,940 lbf | Massive tractive force for deep ripping |
5. Professional Logistics Note
The 1985 CAT D7G is a high-liquidity asset in the secondary heavy equipment market. Because the machine lacks complex electronic control modules (ECMs), it is immune to the common sensor-related failures that plague modern equipment. For international buyers, this model offers a significantly lower total cost of ownership (TCO), as parts are globally available via aftermarket supply chains and the machine can be fully overhauled in standard regional repair shops without requiring specialized factory software.
