Checking Air Compressors (If Equipped)

RG12738-UN-07NOV02

Air Conditioner Compressor (Option A)

Air compressors are offered as an option with John Deere OEM engines to provide compressed air to operate air-powered devices.

Air compressors are engine-driven, piston type devices. They are either air cooled or cooled with engine coolant. The compressors are lubricated with engine oil. The compressor runs continuously by gear or spline drive 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 the 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 with a new or remanufactured unit.
