SKU: SMA-111282C1 Temperature Control Knob for International Harvester and Case IH 86/88 Series Tractors and Combines

When you can't control the heater or blower in your IH cab, it's usually this little knob that's given up. Whether it's cracked from years of sun exposure or the D-shaped shaft has stripped out, a bad temperature control knob leaves you sweating in summer or freezing in winter. This TISCO replacement gets your cab climate controls working properly again, so you can focus on the job at hand instead of being miserable in the seat.

What You're Getting

• Direct replacement for worn or broken temperature control knobs
• Works with blower switch, thermostatic switch, heater control and wiper switch functions
• Proper D-shaped shaft design with flat at 12 o'clock and point at 6 o'clock
• Durable construction that handles daily use and temperature extremes
• TISCO quality - built to match original specifications

Built for Real Farm Work

This knob fits a wide range of International Harvester 86 and 88 series tractors, from the smaller 186 Hydro up through the big 7488 models that handle the heavy tillage and planting work. It also works on various Case combines including the 1644, 1666, and larger models up to the 2055. Whether you're running a utility tractor for chores or a high-horsepower machine for field work, proper cab climate control makes long days much more bearable.

Made to Last

Cab control knobs take more abuse than most folks realize - constant twisting, exposure to sunlight through the cab glass, and temperature swings from hot summer days to cold morning startups. This replacement knob is built to handle the punishment, with materials that resist cracking and a shaft design that won't strip out under normal use.

Installation Notes

The knob simply pulls off the old shaft and pushes onto the new one - the D-shaped design ensures it goes on in the right orientation. If your old knob is really stuck, a gentle rocking motion while pulling usually frees it up. Take a quick look at the switch assembly while you're in there to make sure everything else is working smoothly.
