Komatsu D85A-18(S/N 25001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D85A-18 is a mid-size crawler tractor designed for heavy earthmoving and construction applications. This machine belongs to the D85 series, featuring a turbocharged NT-855 6-cylinder engine with 855 cu in (14.1 L) displacement, producing 220 hp at 1800 rpm. The unit operates within a weight class of approximately 52,051 lb (23,610 kg). Configurations for this series include standard (A), wide-track (EX/PX), and low ground pressure (P) variants.
The D85A-18 represents a specific generation in the Komatsu lineage, characterized by its robust TF-type transmission with 3 forward and 3 reverse gears. This series is valued for its mechanical durability and parts availability. Maintenance of the undercarriage components, such as the 38 shoes per side and 6 track rollers, remains critical for preserving operational efficiency in high-wear environments.

Servicing the D85A-18(S/N 25001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Monitor engine oil for diesel dilution, a known issue on NT-8SS engines. Regularly sample transmission and hydraulic fluids to detect metal particulates that indicate internal wear in the TF transmission or pump. Check cooling system fluid for contamination. Use these analyses to prevent unplanned downtime and extend component life beyond standard intervals.
Corrective & Common Repairs
Address hydraulic leaks at the blade linkage and cylinder seals immediately to maintain pressure. If the machine fails to engage gears, inspect the transmission pump and engagement mechanism for debris or wear. Monitor for white smoke during startup, which may indicate fuel injector or pump issues. Ensure all electrical connections are tight to prevent sensor-related fault codes.
Overhaul & Rebuild Points
Plan major overhauls around the engine and powertrain. Focus on rebuilding the 6-cylinder NT-855 engine when compression drops or oil consumption increases. During undercarriage rebuilds, evaluate the condition of all 38 track shoes, 6 track rollers per side, and 2 carrier rollers per side. Rebuilding the transmission is necessary if gear engagement becomes inconsistent.
Seasonal & Environment Servicing
In cold weather, ensure the cooling system is prepared for low temperatures and check battery health for high-load starts. In high-debris environments, increase frequency of radiator cleaning and undercarriage inspections to prevent track packing. For long storage periods, drain fuel systems to prevent moisture buildup and inspect all hydraulic hoses for dry rot or cracking.

D85A-18(S/N 25001-UP) serial number reference
The PIN plate is located on the front frame casting, typically on the operator's left side near the radiator support. To read the prefix, identify the first character (e.g., 'D' for Dozer) and the subsequent numeric class.
| Prefix | Identifies | Notes |
|---|---|---|
| D | D85A-18 | Identifies Crawler Dozer family. Numeric value indicates size/weight class. Suffix 'A' denotes standard configuration. |
Frequently asked questions
What engine is installed in the D85A-18?
The machine is powered by a Komatsu NT-855 turbocharged 6-cylinder engine with 855 cu in (14.1 L) displacement.
What is the operating weight of this bulldozer?
The standard operating weight for the D85A-18 is approximately 52,051 lb (23,610 kg).
What model replaced the D85A-18?
Specific successor models vary by region and emissions requirements; however, later generations like the D85EX-18 utilize different engine technologies such as the SAA6D125E-7.
What D85A-18(S/N 25001-UP) owners discuss
What are common transmission and hydraulic issues observed in D85A-18 units after long periods of inactivity?
Units often experience hydraulic system leaks and failures in transmission engagement following extended storage. Operators may find the machine starts but fails to drive, which can be linked to transmission pump or pressure issues.
What specific engine-related symptoms should be monitored on the D85A-18 (S/N 25001-UP)?
Reports indicate instances of diesel fuel migrating into the oil sump. This is often accompanied by hard starting conditions and heavy white smoke emissions for several minutes after startup.
What are the typical undercarriage specifications for this machine type?
The standard configuration features 38 shoes per side, 6 track rollers per side, and 2 carrier rollers per side. The track pitch is approximately 8.51 in (21.6 cm) to 9 in (22.8 cm), and the standard shoe size is roughly 22 in (56 cm).
What engine model is used in the Komatsu D85A-18 (S/N 25001-UP)?
The machine utilizes the NT-855 turbocharged engine, which features 6 cylinders and a displacement of 855 cu in (14.0 L).
What should be checked when inspecting a used D85A-18 for potential mechanical failure?
Inspect the magnetic filter for metal debris to check for internal transmission or hydraulic wear. Additionally, verify hydraulic oil levels and quality, and check for any signs of diesel contamination in the engine oil.
Are there known issues with gear engagement on cold starts?
Some operators report a failure to engage gears immediately upon a cold start. In some cases, running the engine for several minutes and then restarting the machine allows it to go into gear.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
