Steering wheel spinner knob 331/27411 JCB 3CX/4CX, genuine

For the JCB 3CX and 4CX backhoe loaders: steering wheel spinner knob 331/27411, a genuine JCB part.

The knob is chosen by part number for the wheel rim section and fixing style. It is important to tighten the clamp so that it neither crushes nor slips on the rim. The position is chosen so that the knob does not hit the levers or panel when the wheel is turned fully. The knob matters for safe steering; any looseness is tightened at once and a knob with a worn bearing is replaced. If the bearing of the turning part gets dirty, the knob can be removed and cleaned.
