What it is

The Sime 6201504 is a trimmer spindle measuring 5 mm in diameter and 34 mm in length. It forms the shaft that links the control knob to the gas valve or trimmer assembly on Sime gas boilers, allowing the setting to be adjusted from the front of the appliance. It is a control knob component listed within Sime gas boiler spares.

Signs this part needs replacing

  • The control knob turns freely without altering the boiler setting
  • The spindle is worn, rounded or flattened where the knob grips it
  • The knob sits loose on the shaft and will not hold its position
  • The spindle is bent or snapped, so the control cannot be operated
  • The knob cannot be turned because the spindle has seized or stripped

Before you order

  • Measure the old spindle to confirm the 5 mm diameter and 34 mm length
  • Check the boiler model number against the fit list above
  • Inspect the control knob and its fixing for wear before refitting
  • Confirm the spindle is the correct item for the valve or trimmer assembly on your appliance
