Komatsu D80A-18(S/N 25001-UP)

Maintenance schedule, common problems & OEM parts breakdown

The Komatsu D80A-18 is a heavy crawler tractor (dozer) in the 200-250 hp class, powered by a 6-cylinder NT-855 engine producing 220 hp gross power. It has an operating weight of approximately 51,390 lb (23,310 kg) and was produced for serial numbers 25001 and up. The machine features a direct drive transmission with 5 forward and 4 reverse gears, a standard blade with 8.5 yd³ capacity, and an undercarriage with 38 shoes per side. It succeeded earlier D80A variants and was followed by the D80E-18 and D80P-18 series.

Across the D80A-18, D80E-18, and D80P-18 generations, the core chassis and powertrain remained consistent, but emissions systems and engine management evolved to meet regional standards. The D80A-18 matters in the used and parts market because its simple, robust NT-855 engine and direct-drive transmission are widely supported by aftermarket components. Its heavy undercarriage and high operating weight make it a staple in mining and large-scale earthmoving, ensuring steady demand for replacement tracks, rollers, and engine parts.

Servicing the D80A-18(S/N 25001-UP) beyond the schedule

Predictive Maintenance & Fluid Analysis

Use KOWA fluid analysis at every major service interval to monitor engine wear metals, hydraulic particle counts, and coolant SCA levels. Check final drive oil levels at 250 hours and change at 1,000 hours. Monitor transmission oil condition at 1,000 hours. Track undercarriage wear visually at 500 hours and measure at 1,000 hours. Inspect turbocharger condition at 1,000 hours. Test battery load at 500 hours.

Corrective & Common Repairs

Address hydraulic hose leaks and cracked fittings during daily checks. Replace fuel filters and drain water separators at 500 hours to prevent injector issues. Check and torque ROPS bolts and cutting edge bolts at 2,000 hours. Inspect track tension and shoe condition daily to prevent premature undercarriage wear. Replace hydraulic return filters at 500 hours. Check belt and hose integrity at 250 hours.

Overhaul & Rebuild Points

Plan major engine overhaul based on KOWA analysis and hour count, typically around 10,000-15,000 hours for the NT-855. Rebuild transmission and torque converter at 2,000 hours or if slippage occurs. Inspect final drives for oil leaks and wear at 1,000 hours. Replace undercarriage components (rollers, sprockets, idlers) based on wear measurements at 1,000 hours. Check structural welds at 1,000 hours.

Seasonal & Environment Servicing

In cold weather, ensure coolant concentration is adequate and drain water from fuel separator daily. In hot weather, clean radiator and oil cooler fins daily to prevent overheating. Check DEF level on Tier 4 models daily. Inspect air filter restriction indicator frequently in dusty conditions. Grease all points more often in abrasive environments. Check track tension regularly on rocky terrain.

Frequently asked questions

What engine does the Komatsu D80A-18 use?

The Komatsu D80A-18 uses a 6-cylinder NT-855 engine with 220 hp gross power and 855 cu in displacement.

What is the operating weight of the Komatsu D80A-18?

The operating weight is 51,390 lb (23,310 kg).

What model replaced the Komatsu D80A-18?

The D80A-18 was succeeded by the D80E-18 and D80P-18 series, which feature updated emissions systems and engine management while retaining the same chassis and powertrain architecture.

What D80A-18(S/N 25001-UP) owners discuss

What engine powers the Komatsu D80A-18 (S/N 25001-UP), and what are its key performance specifications?
The Komatsu D80A-18 (S/N 25001-UP) uses a Cummins NT-855 engine. It produces 220 hp (164 kW) gross power at 1800 rpm with a maximum torque of 759 lbs ft (1,029 nm). The engine has 6 cylinders and a displacement of 855 cu in (14,011 cu cm). The cooling system holds 21 gal (79 l) of fluid, and the fuel tank capacity is 119 gal (450 l). Note: The D80A-12 variant uses a different engine with 180 hp gross power; do not mix these specifications.
What are the typical undercarriage wear patterns and specifications for the D80A-18?
The D80A-18 features a track gauge of 6.6 ft (2 m) and standard shoe size of 22 in (56 cm). It has 38 shoes per side, 6 track rollers per side, and 2 carrier rollers per side. Ground pressure is approximately 8.7 psi. Undercarriage wear typically manifests as track chain elongation and roller/bushing wear. The track pitch is 9 in (22 cm). Operators should monitor track tension to prevent excessive wear on the idler and sprocket.
How does the D80A-18 powertrain and transmission behave, and what are its speed limits?
The machine uses a DD (Direct Drive) transmission with 5 forward gears and 4 reverse gears. Maximum forward speed is 5 mph (8 kph), and maximum reverse speed is 5.6 mph (9 kph). The powertrain is designed for heavy earthmoving; operators report smooth power delivery but note that hydraulic pump wear can correlate with engine stress. If a hydraulic pump fails, the engine may be at risk due to the high load. The transmission is robust but requires regular fluid checks to prevent gear wear.
What are common hydraulic system issues and maintenance requirements for this model?
Common hydraulic issues include slow functions when hot, indicating internal leakage in pumps or valves as viscosity drops. The hydraulic system requires Komatsu EO or equivalent high-quality hydraulic oil. Filters must be changed at recommended intervals to prevent contamination. Operators should check for leaks in hydraulic lines and cylinders, especially around the main control valve. Weak performance in cold conditions may indicate air ingress or low fluid levels. The cooling system for the hydraulic oil must be kept clean to prevent overheating.
What electrical or sensor quirks are associated with the D80A-18 series?
The D80A-18 relies on electronic control systems for monitoring and safety. Common issues include intermittent starting, dashboard failures, or random shutdowns due to faulty sensors or unstable power supplies. Grounding issues can cause multiple fault codes. Operators should check battery terminals, engine/chassis grounds, and main starter cables if starting problems occur. Sensor malfunctions can trigger false warnings; verify sensor connections and wiring harness integrity before replacing components.
What is the operating weight and blade capacity of the D80A-18?
The operating weight of the D80A-18 is 51,390 lbs (23,310 kg). The standard blade has a capacity of 9 cu yd (6 cu m), with a height of 52 in (132 cm) and a width of 13 ft (4 m). The machine length with the blade is 22 ft (7 m), and without the blade, it is 16 ft (5 m). The height to the top of the cab is 9.8 ft (3 m). Width over tracks is 9.8 ft (3 m). Ground clearance is 0 ft (0 m). Note: Weights and dimensions can vary by configuration and attachment package.
What to check when buying a used D80A-18 (S/N 25001-UP)?
Verify the serial number is 25001 and up to ensure correct manual and parts application. Check the engine for oil burning and coolant leaks. Inspect the undercarriage for wear on shoes, rollers, and idlers. Test all hydraulic functions for speed and strength, both cold and hot. Check for electrical faults, intermittent dashboard warnings, and starting issues. Ensure the transmission shifts smoothly through all gears. Verify the condition of the cooling package (radiator, oil cooler) for blockages. Have your dealer verify the engine and hydraulic pump condition before purchase.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
