This complete assembly gives you everything you need to restore that three-cylinder workhorse to like-new condition.
What You’re Getting
- Complete crankshaft with matched bearing set—no guesswork on clearances
- Modern lip seal design that seals better and installs easier than old rope seals
- Precision ground journals for exact specifications
- Properly positioned keyway for timing gear alignment
- Ready to drop in for AD3.152 engines across multiple brands
Built for Real Farm Work
This crankshaft fits the legendary AD3.152 engines that power everything from MF 135s and 240s to various Landini and Same tractors. These three-cylinder engines are known for running forever when maintained properly, but eventually even the best engines need internal work. Whether your tractor’s been moving hay, running a loader, or pulling tillage equipment, this rebuild gets you back to full power.
Made to Last
The matched bearings come sized specifically for this crank—never mix components from different sources. The lip seal design eliminates the hassle and potential leaks of rope seals while providing superior oil control. Each journal is precision ground to factory specifications for proper clearance and long life.
Good to Know
This is precision work that rewards attention to detail. Use Plastigage to verify all clearances before final assembly. The block may need line-boring if main bearing bores show wear. Keep everything spotless during assembly—cleanliness is critical for bearing life. Follow proper torque specifications and assembly sequence for best results.
