Create your own by using the measurements from the diagram
shown on the previous page.
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.
Once the shaft is modified slide the
coupler onto the shaft. Mark and
drill the shaft so that it has a dimple
for the set screw. We recommend a
5/16 drill, just deep enough to sink
the point of the drill bit. (Figure 1)
This will allow you to anchor the set
screw to the shaft. Use locktite to
secure the setscrew and jam nut
from the coupler to the shaft.
Now you can install the gearbox back on the frame.
Note: The gearbox was probably turned during this process and
needs to be re-centered. Do this by turning the gearbox all the way
in one direction and then count the turns in the opposite direction
until the box stops. For example: Let’s say the count was 4.5…
divide that by 2. In this case bring the box back 2 ¼ turns and it is
centered.
Now the pitman arm can be re-attached and tightened. Once that
is completed the car can be set back down on its tires. Verify the
wheels are still pointed straight ahead.
