I have a Turner AWD system installed on one of my mountain bikes. The front wheel has a single speed Sachs freewheel that may need replacing due grit in the freewheel. I'm speculating this mates to the same Park FR-6 tool as is common on most bmx freewheels, but thought I could give some dimensions to confirm before I order the tool.

The freewheel has a 4 notch removal pattern, the outside diameter of the cross notches is about 40mm, the notches are individually 2mm deep radially and 8 mm wide about the circumferential arc.


Are these the dimensions for a freewheel that mates with the Park FR-6?
If not, any other candidates?
