The shaft of the gearbox will now
need to be cut into a DD shaft.
This is a round shaft with flats
centered on two sides. An easy way to do this is to make a paper template.
Create your own template by using the measurements from the diagram
below.
Starting from an 1/8 from the bottom, wrap the paper template around the
shaft and match the horizontal arrows together.
Mark the shaft at the 8 vertical arrow points and draw a line down the length
of the shaft, connecting the marks. This will create the shaded “D” sections
found on the template.
With a grinder or similar tool, grind flat the shaded “D” sections to match
the DD shaft. As you work, use the coupler as a guide and test fit to ensure
proper fitting.
Another option would be to remove the gearbox and take it to your local
machine shop to be modified.
