When you’re rebuilding that classic Ford 9N, 2N, or 8N engine and the crankshaft journals have been turned .020″ undersize, these bearings are exactly what you need to get things back to proper clearances. A worn-out engine with rod knock or low oil pressure usually means it’s time for a rebuild, and these undersize bearings let you salvage a good crankshaft that’s been machined to clean up wear and scoring.
What You’re Getting
- Complete set of four rod bearings sized .020″ under standard to match machined crankshaft journals
- TISCO quality construction that meets or exceeds original Ford specifications
- Precise bearing clearances for proper oil flow and engine protection
- Direct replacement for factory bearings when crankshaft has been turned undersize
Built for Real Farm Work
These bearings are designed for the flathead Ford engines that powered thousands of 9N, 2N, and 8N tractors from 1939 to 1952. Whether your old Ford is used for mowing, cultivating, or just weekend projects around the farm, these bearings will handle the job. The 119-cubic-inch flathead engine in these tractors was built tough, and with proper bearings it’ll run another lifetime.
Made to Last
Engine bearings take tremendous loads from combustion pressure and the reciprocating motion of the rods and pistons. These TISCO bearings are manufactured with the right bearing material and precise tolerances to handle those forces while maintaining the oil film that keeps everything running smoothly. They’re built to work with the 20-weight oil these old engines prefer and the operating temperatures of agricultural work.
Good to Know
Installing rod bearings requires splitting the engine case and removing the rods and pistons—it’s a complete teardown job. This is typically done as part of a full rebuild along with new rings, gaskets, and main bearings. Make sure your machine shop has turned the rod journals exactly .020″ undersize before ordering, and check that all four journals measure the same. A good rebuild with quality parts like these can give your old Ford decades of reliable service.
