Description
When your tachometer starts jumping around or quits reading altogether, chances are it’s the cable that’s gone bad. These old IH diesel tractors work hard and put a lot of vibration through that tach cable over the years. A worn cable gives you false readings or no readings at all—and when you’re trying to maintain proper RPMs for your PTO or keep your engine running efficiently, you need that gauge working right.
What You’re Getting
- Heavy-duty 80-inch cable with protective metal covering that handles engine vibration
- Direct replacement for original International Harvester tachometer systems
- Durable construction built to match the quality of your vintage IH tractor
- Proper length and connections for a straightforward installation
Built for Real Farm Work
This cable is designed for the legendary International Harvester diesel tractors that built America’s farms—from the smaller utility 666 and 766 models up through the big 3088 and 3288 row-crop workhorses. Whether you’re running a hay mower, pulling a disk, or powering a grain elevator, these tractors need accurate RPM readings to do their job efficiently.
Made to Last
The metal covering protects the inner cable from heat, moisture, and the constant flexing that comes with tractor operation. This isn’t some flimsy aftermarket piece—it’s built to handle the demands of diesel farm work and give you years of reliable service.
Good to Know
Installation involves disconnecting the old cable at both the tachometer and the engine, then routing the new one the same way. Take your time routing it away from hot exhaust components and sharp edges. A little white lithium grease on the connections helps things go together smoothly and prevents corrosion.
