Tractor cab air conditioning update kits allow you to retrofit or upgrade the AC system on older equipment to modern R-134a refrigerant — restoring cool, comfortable cab conditions without the cost of a full system replacement. Quality Farm Supply stocks air conditioning update kits for a wide range of tractors and agricultural equipment, including complete conversion kits with the compressor, condenser, receiver-drier, and hardware needed for a full system refresh.
Whether your tractor's original R-12 system has failed and you need to convert to R-134a, or your existing AC system needs a full component refresh, an AC update kit gives you everything in one box to get the job done right. Shop by make and model to find the correct air conditioning update kit for your tractor.

Air Conditioning Update Kit for International 66 to 86 Series
SKU:QFS-990-3566
Updates International 66 Series Tractors to 86 Series Standards
If you're running a International 1066, 1466, 1566, 766, or 966 tractor, you already know the 66 Series A/C system is aging — and parts are getting harder to find. The good news: a complete bolt-on upgrade kit exists that brings your cooling system up to 86 Series standards, with a modern Sanden compressor at the heart of it.
What's Included in the Kit (SKU: QFS-990-3566)
This kit is a comprehensive, all-in-one solution. Everything you need for a complete conversion is in the box:
- Sanden Conversion Kit — replaces the original York or Tecumseh compressor with a modern, efficient Sanden rotary compressor
- 86 Series Evaporator — updated evaporator core matched to the new system
- 86 Series Condenser and Line Kit — upgraded condenser with all necessary lines and fittings
- 86 Series Oil Cooler — keeps hydraulic temps in check alongside the A/C upgrade
- Mounting Brackets — bolt-on fitment, no fabrication required
- Belt — sized for the Sanden compressor
- Thermostatic Switch — controls evaporator temperature to prevent freeze-up
- Condenser Mounted Binary Switch — protects the system from high/low pressure extremes
Compatible Tractor Models
This kit is designed to fit the following International tractor models:
- International 766
- International 966
- International 1066
- International 1466
- International 1566
Why Upgrade to the 86 Series A/C System?
The original 66 Series A/C systems used older York or Tecumseh piston compressors — heavy, inefficient, and increasingly difficult to source parts for. The Sanden rotary compressor used in this kit offers several key advantages:
- Lighter weight — less parasitic load on the engine
- More efficient cooling — better heat exchange at lower RPMs, which matters during field work
- R134a compatible — works with the modern, readily available refrigerant standard
- Widely serviceable — any shop with modern A/C equipment can service a Sanden system
Installation Notes
This is a bolt-on kit designed for the 66 to 86 Series conversion — no custom fabrication is required. However, as with any A/C conversion, we recommend:
- Flushing the system thoroughly before installing new components
- Replacing all O-rings with HNBR (green) O-rings compatible with R134a
- Using the correct PAG oil for the Sanden compressor — do not mix with old mineral oil
- Having the system evacuated and recharged by a certified technician with R134a equipment
