Air Compressor (Optional)
Air compressors are offered as options with John Deere
OEM engines to provide compressed air to operate
air-powered devices like vehicle air brakes.
Air compressors are engine-driven piston types. They are
either air cooled or cooled with engine coolant. The
compressors are lubricated with engine oil. The
compressor runs continuously as gear or spline driven by
the auxiliary drive of the engine but has “loaded” and
“unloaded” operating modes. This is controlled by the
vehicle’s air system (refer to vehicle technical manual for
complete air system checks and services).
See your John Deere engine distributor or servicing dealer
for diagnostic and troubleshooting information. If diagnosis
leads to an internal fault in the compressor, replace the
complete compressor as a new or remanufactured unit.
