This is a write up for installing an Mtech wheel to replace your airbag wheel. There is a thread for this, however, no one has included a schematic or dimensions for a needed steering wheel spacer, and only stated that a spacer was needed. Below is everything you will need to complete this job.
Background/Problem:
When I bought my car last month the previous owner told me he did not have a functioning horn becuase he had to take off the horn slipring and turn signal reset tab on the back of the wheel to make the Mtech wheel fit.
I took off the wheel and noticed that the previous owner was using a oversized nut as a washer to move the wheel closer to the driver. I decided to take out the nut and reinstall the wheel. When I retightened the steering wheel retention nut, I noticed that the nut was bottoming out on the threads and was not pressed tightly against the wheel. There was about 1/2" of pay in the wheel along the steering shaft axis.
Solution/Part Dimensions:
A spacer is needed to be placed onto the steering shaft after the wheel is placed onto the splines. (See schematic below - spacer is shaded in red). I took some measurements and came up with the following dimensions:
ID = 0.75", OD = 1.125", t = 0.5". My coworker just got his mini lathe back up and running to work on his airplane, and he was nice enough to make a spacer for me. Perfect fit! Hope this helps you all. FYI, the stock spacer is used behind the wheel and allows the turn signal tab to be reset. If the spacer described above is used behind the steering wheel, the turn signal arm will not be reset.
Materials:
I had planned on buying this part from McMaster-Carr (92510A850) and then ask my coworker to downturn the OD from 1.5" to 1.125", be he had some scrap aluminum in his shop. Saved me $20!
Drawing/Dimensions for Reference:
Here is my thought process and the dimensions for reference.
Final Product:
