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

If you're unsure whether this kit fits your specific tractor configuration, contact our team — we're happy to help confirm fitment before you order.
