Belt Adjustment Wheel Autohelm 4000, ST4000

This is the belt adjustment wheel for the Autohelm 4000 wheel pilot. This is not the drive wheel, that is available separately. This 3D printed wheel does not have the brass sleeve in it that the original part had, but it works very well with just a thin layer of grease to lubricate it.

The belt drive wheel and belt adjustment wheel differ slightly in that the adjustment wheel has a significantly smaller hub diameter.
