I compared the two today and a Toro is not a rebadged Fairey inside
either. The components are very similar, and most of the bearings seem
to be the same. The input and output shafts are the same size on the
bearing surfaces, and the same length. The Toro has corser splines where
the synchro goes, and a larger diameter synchro. The gears are also
wider on the contact area than the Fairey. The Toro has 22 and 25 teeth
on the od gears, while the Fairey has 23 and 26 teeth. So other than
bearings and possibly the intermediate shaft(with some shortening going
from fairey to toro), no parts are interchangeable between the two.
However, if you took ALL the Fairey internals or All the Toro internals,
they could be assembled in the other overdrive's case. One point Ralph
noted about the Fairey is that he was never sure if the oil level was
checked with the stick screwed in or just pushed in. After comparing
to the Toro, it appears that the dipstick should NOT be screwed in to
check the oil level in a Fairey. Also, the seals for the input and
output shafts seem to be the same on both units.
