Description

When your Ford tractor starts missing and running rough, or you notice that familiar sputter when you’re trying to get work done, the problem’s often hiding right inside the distributor. This rotor is designed for FDN12127A and 311185 distributors, and it’s the part that sends spark to each cylinder at just the right time. Without a good rotor, you’re not getting reliable ignition.

Key Features

Precision timing that keeps your engine running smooth and strong under load
Durable construction that handles the heat and vibration inside the distributor
Direct OEM replacement—no modifications or adjustments needed
Reliable contact points that ensure consistent spark delivery to all cylinders

Built for Real Farm Work

This rotor fits Ford 8N tractors from serial number 263844 and up, plus the 501, 600, 601, 700, 800, 801, 900, 901, 2000, and 4000 Series from 1950 to 1964. These are the workhorses that helped build American agriculture—utility tractors that handled everything from cultivating corn to running hay equipment. Whether you’re running a brush hog, pulling a disc, or operating a PTO-driven implement, this rotor keeps the spark consistent.

Made to Last

Farm equipment ignition systems take a beating from dust, moisture, and vibration. This TISCO-manufactured rotor is built to handle those conditions with materials that resist corrosion and wear. The contact surfaces are designed to maintain good electrical connection even after thousands of hours of operation.

Installation Notes

Swapping out the rotor is straightforward once you’ve got the distributor cap off. Just pull the old rotor straight up and press the new one down until it seats properly. While you’re in there, it’s a good time to check your points gap and condenser—if the rotor was worn, those components probably need attention too.
