Description
If you’ve been hearing that rough grumble from the clutch area when you let out the pedal, or feeling extra vibration through the tractor during starts and stops, your pilot bearing is likely crying for help. This small but critical bearing sits inside the flywheel and supports the transmission input shaft, keeping everything aligned when your clutch engages and disengages. When it wears out, you’ll know it—and so will everyone within earshot.
What You’re Getting
- Quality TISCO construction that’s built to handle the constant rotation and loads of farm work
- Precision fit that centers your transmission input shaft exactly where it needs to be
- Sealed design that keeps out dirt and moisture while holding in lubrication longer
- Direct replacement for your original bearing—no modifications or special tools needed
Built for Real Farm Work
This pilot bearing serves a wide range of Allis Chalmers tractors from the classic letter series like your B, C, WC, and WD models up through the numbered series including the 170, 180, 190, and 200 models. Whether you’re running a vintage WD45 for hay work or keeping a D17 going strong for general farm duties, this bearing handles the job of supporting that input shaft through thousands of clutch cycles.
Made to Last
Farm equipment bearings take punishment from vibration, dirt, temperature swings, and constant use. This TISCO bearing uses quality materials and proper tolerances to handle the loads your Allis Chalmers puts on it. The sealed construction keeps contamination out and lubrication in, so it keeps doing its job season after season without the noise and roughness that worn bearings cause.
Installation Notes
You’ll need to split the tractor to reach this bearing, so it’s a good time to check your clutch disc and pressure plate while you’re in there. The bearing presses into the flywheel and should slide onto the input shaft smoothly when everything’s properly aligned. A pilot bearing puller makes removal much easier than trying to pry it out.
