Description
When your Allis Chalmers engine starts knocking or showing low oil pressure, worn main bearings are often the culprit. These critical components keep your crankshaft properly supported and lubricated, and when they wear out, your whole engine suffers. This .010″ undersized bearing set is designed for engines where the crankshaft journal has been turned down during a rebuild.
What You’re Getting
- Precision-manufactured bearings sized exactly .010″ under standard to match turned crankshafts
- Complete set covers all main bearing positions for a thorough rebuild
- High-quality steel-backed construction with proper bearing material composition
- Engineered to restore proper oil clearances and eliminate bearing knock
Built for Engine Rebuilds
These undersized bearings are essential for rebuilding Allis Chalmers tractors after machine shop work. When rebuilding an engine, machine shops often turn the crankshaft journals to remove wear and scoring, requiring undersized bearings to maintain proper clearances. This bearing set restores your engine to factory specifications with the correct oil film thickness.
Made to Last
TISCO bearings are manufactured to meet or exceed original equipment standards, using proven bearing alloys that handle the heat and pressure of hard-working tractor engines. The steel backing provides structural strength while the bearing surface material ensures proper lubrication and long service life under field conditions.
Installation Notes
Make sure your crankshaft has been properly machined to .010″ under before installing these bearings. Always verify bearing clearances with Plastigage during assembly, and torque bearing caps to factory specifications. A good practice is to pre-lubricate all bearing surfaces during installation to prevent dry startup damage.
