Servicing the D355A-5(S/N 12622-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Regularly analyze engine oil and hydraulic fluids to detect internal wear. Monitor the 19 gal (71 L) engine oil capacity for metal particulates. Use Komatsu genuine oils to maintain lubrication integrity. Track fuel consumption trends to identify injector or turbocharger efficiency drops. Periodic sampling of transmission and final drive oils can prevent catastrophic gear failure in high-torque applications.
Corrective & Common Repairs
Address hydraulic leaks immediately to protect the 74 gal (280 L) hydraulic tank capacity. Monitor for track slackness, as tension loss can lead to accelerated undercarriage wear. Inspect the 24V electrical system and alternator output if starting issues occur. Check blade tilt cylinders and ripper lift cylinders for seal degradation or pressure loss during heavy penetration tasks.
Overhaul & Rebuild Points
Plan major engine overhauls when compression drops in the 1175.4 cu in (19261.4 cc) SA6D155-4 block. Evaluate transmission rebuild requirements if Torqflow efficiency decreases or gear engagement becomes erratic. Inspect undercarriage components, including the 39 shoes per side and 7 track rollers per side, for end-of-life wear. Rebuild hydraulic pumps when flow capacity falls below factory specifications.
Seasonal & Environment Servicing
In dusty environments, increase frequency of air cleaner inspections to prevent engine aspiration issues. During high-temperature operations, ensure the 4TR gal (175 L) cooling system is free of debris to prevent overheating. In cold climates, utilize single-grade oils matching ambient temperatures as specified in the shop manual. Clean radiator cores frequently to maintain optimal airflow for the turbocharged system.

| D355A-5 | Standard Configuration | Identifies the D3TR crawler dozer family. Covers serial numbers 12622 and up. Equipped with the SA6D155-4 engine (410 hp gross). Standard blade and undercarriage specifications apply to this serial range. |
Frequently asked questions
What engine is installed in the D355A-5 (S/N 12622-UP)?
This machine is equipped with the Komatsu SA6D155-4, a 6-cylinder, turbocharged and aftercooled engine with a displacement of 1175.4 cu in (19261.4 cc).
What is the operating weight of this bulldozer?
The operating weight is approximately 9806.2 lb (4448 kg), though total weight varies by configuration, such as when a ripper or heavier blade is attached.
What model replaced the D355A-5?
The D355 series has evolved through various dash-number generations (such as -7 and -8) with different engine and emissions configurations, following the lineage of the DTRD1 and D355A-3.
What D355A-5(S/N 12622-UP) owners discuss
What engine is installed in the Komatsu D355A-5 (S/N 12622-UP)?
The machine uses the Komatsu SA6D155-4 engine, which features 6 cylinders and a displacement of 1,175.4 cu in (19,261.4 cc). Gross power is rated at 410 hp (305.7 kW) measured at 2000 rpm.
What are the known hydraulic and steering performance issues reported by operators?
Operators have reported instances of weak steering performance when the machine is hot. Additionally, some users have noted track tension loss where tracks may pump up normally with grease but become slack after a short period of operation.
What are the standard undercarriage specifications for this model?
The standard configuration includes 39 shoes per side, 7 track rollers per side, and 2 carrier rollers per side. The track pitch is approximately 10 in (26 cm) to 10.25 in (26.2 cm), and the standard shoe size is 24 in (61 cm) to 24.1 in (61.2 cm).
What maintenance precautions should be taken regarding engine cooling and lubrication?
The cooling system requires a capacity of approximately 45 liters. For lubrication, it is noted that single-grade oil (such as SAE 10W-30 or 15W-40) can be mixed with multigrade oil, but the addition should match the ambient temperature requirements. Use of Komatsu genuine oil for engine and hydraulic applications is recommended.
What should be checked when inspecting a used D355A-5 (S/N 12622-UP) for purchase?
Verify the exact serial range on the machine plate to ensure parts compatibility. Inspect the engine for coolant leaks, check the undercarriage for rapid tension loss, and evaluate steering response under high operating temperatures. Confirm if the unit has any specific regional emissions packages or attachment configurations that affect weight and transport planning.
