Sullivan-Palatek D185 FAQs
What is a Sullivan-Palatek D185 air compressor?
The Sullivan-Palatek D185 is a 185 CFM tow-behind portable rotary screw air compressor commonly used in construction, sandblasting, paving, and mobile service applications.
Are all D185 compressors the same?
No. D185 compressors were built across multiple generations with different engine options including John Deere, Caterpillar, Deutz, and Isuzu. Parts can vary based on model code and serial number.
What parts are most commonly replaced on a D185?
Common maintenance parts include compressor air filters, oil filters, air/oil separators, compressor oil, fuel filters, and engine oil filters.
How do I find the right parts for my D185?
Start by confirming your full model code and serial number. This information is typically located on the data plate. Many parts vary by engine branch and production revision.
Why is my D185 not building pressure?
Low pressure is often caused by restriction, blowdown valve issues, or control system behavior. Air filters, separators, and inlet control components are common contributors.
Why does my D185 keep shutting down?
Shutdowns are commonly caused by high discharge temperature, cooling system restriction, or sensor inputs on Tier 4 models. Always check filters, separator condition, and airflow first.
What causes oil in the air lines on a D185?
Oil carryover is typically caused by separator restriction, oil return issues, or incorrect oil level. The separator plays a key role in removing oil from compressed air.
What does engine lugging mean on a D185?
Engine lugging usually indicates increased load inside the compressor system. This is often caused by restrictions such as a clogged separator, oil filter, or intake filter.
Do I need to confirm my serial number before ordering parts?
Yes. Serial number breakpoints can affect separator assemblies, cooling components, engine parts, and electrical connections. Confirming serial number helps ensure correct fitment.
What is the difference between mechanical and Tier 4 D185 models?
Mechanical models rely on pneumatic control systems. Tier 4 models include electronic monitoring, sensors, and engine protection logic that can trigger derates or shutdowns.
Can this part fit other Sullivan-Palatek compressors besides the D185?
Some parts may fit multiple Sullivan-Palatek portable models. Always confirm compatibility using your model code and serial number before ordering.
