Description
When your Allis Chalmers engine starts making that telltale knocking sound from the bottom end, worn camshaft bearings are often the culprit. These bearings support the camshaft as it spins thousands of times per minute, operating the valves that keep your engine breathing properly. When they start to wear out, you’ll hear the noise first at idle, then progressively worse under load—and that’s your signal to get them replaced before more expensive damage happens.
What You’re Getting
- Precision-made bearing designed specifically for Allis Chalmers engines
- Proper clearances to maintain oil pressure and reduce wear
- Quality materials that handle the constant rotation and pressure
- Three bearings included—exactly what you need for 201 and 226 CID engines
Built for Real Farm Work
This bearing fits the 4-cylinder gas engines found in many Allis Chalmers tractors from the classic era. The 201 and 226 cubic inch displacement engines were workhorses that powered everything from cultivation to harvesting, and they’re still running on farms today thanks to solid engineering and parts like these that keep them going.
Made to Last
Camshaft bearings take a beating—they’re constantly loaded with pressure from valve springs and spinning at engine speed. These Tisco bearings are manufactured to handle those stresses with the right hardness and surface finish to provide years of reliable service in your engine rebuild.
Good to Know
Installing camshaft bearings requires splitting the engine case, so this isn’t a quick roadside fix. While you’re in there, it’s smart to check the camshaft journals for wear and consider replacing the cam if there’s any scoring or excessive wear. A machine shop can press these in if you don’t have the right tools—proper installation is worth the extra step.
