Description
When you’re fighting the steering wheel on long days in the field, the problem often comes down to a worn steering worm. This 575mm steering worm shaft is the heart of your manual steering system—the threaded shaft that turns your steering wheel motion into actual wheel movement. If your MF 135 or 148 feels loose, wanders down the road, or takes too much muscle to turn, this replacement worm will get you back to precise, predictable steering.
What You’re Getting
- 575mm length designed specifically for straight axle configurations
- Keyed shaft connection eliminates the slipping you get with worn splines
- Precision-threaded worm gear meshes perfectly with your steering box sector
- Built to handle the daily grind of farm work without premature wear
- Direct replacement that installs with your existing steering box components
Built for Real Farm Work
This steering worm fits manual steering systems on Massey Ferguson 135 and 148 tractors with straight axle front ends. These tractors are workhorses on farms and small acreages, handling everything from hay operations to loader work to general transport duties around the property.
Made to Last
The worm gear design has been proven reliable for decades in agricultural applications. This shaft uses quality steel construction and precise machining to ensure smooth operation and long service life, even under the constant stress of steering heavy implements and loaded front-end loaders.
Installation Notes
This worm installs inside your existing steering box assembly. You’ll need to disassemble the steering box to replace the worm, so plan on having the tractor out of service while you work. Make sure to adjust the sector gear mesh properly after installation—too tight causes binding, too loose gives you sloppy steering.
