Secondary Steering Box Shaft for Massey Ferguson 35, 35X, 135, 148, and 240 Series Tractors SKU: QT1850017

When your steering box worm shaft wears out, develops excessive play, or breaks entirely, your tractor becomes difficult to control and potentially dangerous to operate. This secondary steering box shaft restores precise steering response by replacing the worn internal component that translates steering wheel input into front wheel movement.

Why This Part Matters

• Eliminates dangerous steering play that develops as the original shaft wears
• Restores smooth steering operation without binding or loose spots
• Precision-machined to match original equipment specifications
• Built to handle the steering loads and vibrations typical in agricultural environments
