Description
When you’re splitting your tractor or rebuilding the engine, having the right flywheel bolts is crucial. These special bolts connect your flywheel to the crankshaft—one of the most critical connections in your entire tractor. You don’t want to mess around with the wrong bolts here, as a loose or failed flywheel can destroy your transmission or worse.
What You’re Getting
- Genuine 1/2″ x 1-1/2″ UNF fine thread for secure flywheel attachment
- High-strength 10.9 grade steel construction handles extreme torque loads
- Precision threading ensures proper engagement with crankshaft
- Direct OEM replacement—no guessing about fit or specifications
- Built to handle the power and vibration of modern farm tractors
Built for Real Farm Work
This bolt fits a variety of Massey Ferguson models from utility tractors like the 240 up through the powerful 4200, 4300, and 6100 series machines. These are the tractors handling everything from haying and cultivation to heavy loader work and road transport, where flywheel integrity is absolutely critical for safe operation.
Made to Last
The 10.9 grade steel construction means this bolt can handle the extreme forces generated when your engine’s firing. Farm tractors work hard, and flywheel bolts take tremendous stress every time the engine fires and the power gets transferred through the drivetrain.
Installation Notes
Always replace flywheel bolts in complete sets and torque to exact specifications—this isn’t the place to guess. Use thread locker on the threads and check your service manual for the proper torque sequence. When you’re doing major engine work, it’s also smart to check the flywheel face for cracks while you’ve got everything apart.
