Description
When your 4WD Massey’s steering starts feeling loose or you notice the power steering ram moving around more than it should, this pin is likely what you need. This is the adjustable link in your power steering system that keeps everything tight and aligned, and when it wears out, you’ll feel it every time you’re trying to make precise passes or hold a straight line.
What You’re Getting
- 20mm precision-machined pin designed specifically for 390 4WD and similar models
- Hardened steel construction that handles the stress of power steering loads
- Exact replacement for worn original pins that cause steering slop
- Factory specifications ensure proper fit with your steering ram assembly
Built for 4WD Farm Work
This pin fits the 300 series Massey Ferguson 4WD tractors that work hard in challenging conditions. Whether you’re pulling heavy implements through tough soil, operating a loader, or navigating around buildings and equipment, these tractors need precise steering control. The 390 and similar models in this series are known for their reliability in mixed farming operations where steering precision directly affects productivity and safety.
Made to Last
Precision-machined steel construction for maximum durability and longevity with proper heat treatment to resist wear. This isn’t a generic pin – it’s engineered to handle the hydraulic pressures and mechanical stress that power steering systems generate, especially when you’re working the tractor hard.
Installation Notes
This is typically a straightforward replacement once you get the ram disconnected. Sometimes those pins are stubborn after years of service. A bit of heat and a proper pin punch usually does the trick. Make sure to check the bushings and grease fittings while you have everything apart – worn bushings will eat up a new pin quickly.
