    Re: Scorpion safety

    A few years ago a friend lost control of his Scorpion on some light snow in the mountains above Golden, Colorado. He ended up upside-down in a ravine

    Both the X1/9 and the X1/20 were designed to meet what Fiat presumed were to be very rigorous new US crash standards; both cars are very robust.

  • Installing a Beta gearbox into a Scorpion/Montecarlo

    A few years back I installed an NOS gearbox from a Beta VX into my Scorpion WITHOUT disassembling, reaming out the shift-shaft, and reassembling, which, was the normal approach that people took. I promised to do a write up and I was just asked by a user to fill him in on what I had done. So here goes.

    Edit: The VX gearbox did not come with a differential or cover. The VX ring gear was included which I mounted on the Scorpion differential. If you keep the Beta differential you'd also need to use the stub axle and flange from the Scorpion on the passenger side. Also, if you use the Beta differential cover you will need to change the speedometer drive gear. I used the Scorpion cover which did not require a change in speedo gear.

    The shift shaft modification was actually quite simple. It just required a bit of patience, careful measurement, and hand work with a small grinder, file, and drill. It only took an hour or so.

    Basically, you have to cut a small amount off the end of the Beta shift shaft, square the top so that the Scorpion shift lever will fit onto it, and drill a hole to allow mounting the shift lever.

    The attached pictures illustrate the process.

    First, make sure the gearbox is in neutral on both gearboxes, then carefully measure the top of the Scorpion shift shaft to document the configuration you are trying to achieve. Make sure to correctly document the orientation of the squared sides before you start grinding the flats on the Beta shift shaft.

    These are my measurements but I'm not sure I could still interpret them without a gearbox in front of me. Hopefully, they will be helpful to someone else.

    Next, you have to replace the top nut with one from a Scorpion gearbox. It's straightforward but requires a large socket with a thin wall to clear the case casting. I bought a socket from Harbor Freight and ground down the outside diameter until it fit.

    After replacing the nut, cut the Beta shift shaft off to the same height above the nut as the shaft on the Scorpion gearbox then, smooth the cut with a file.

    Next, mark the lines of the flats on top of the cut shaft. I placed the Scorpion shift lever on top of the newly cut Beta shaft to mark the guide lines. I then protected the shaft penetration and seal with masking tape and used a small hand grinder to rough-in the flats. I finished them with a file until the shift lever would fit nicely onto the shaft. Just be careful not to take off too much material with the grinder before starting with the file.

    Attachment 12132Attachment 12133Attachment 12134

    Once you get the Scorpion shift lever to fit on correctly, you can use it as a guide to drill the required bolt hole. Once you get the bolt hole drilled, chamfer the hole on each side a bit to make the bolt insertion easier.

      DJ thanks for the write up. Do you remember which spring you used? Short or long?
      Thanks
      Ralph.

      My memory is bad, but I seem to remember also having to use the Scorpion's passenger-side stub axle and flange. The Beta had an intermediate driveshaft that slide over the splined stub axle, but there were no threads to hold on the Scorpion's flange. Also had to drill and tap the front motor mounting points. I think the speedo gearing was different too; maybe.

      I transferred the parts from the Scorpion which are the one on the right. Short spring.

      I should have added that the VX box did not come with a differential or cover. The VX ring gear was included which I mounted on the Scorpion differential. I used the Scorpion cover which did not require a change in speedo gear.

      I didn't have to do anything to the mounting points.

      I'm at the point of reassembly. I have a question regarding the differential unit. Can I put the scorpion's Ring with two cv stub axles straight in the beta trans with out any worry? Do I have to worry about pre-load?

      Also can I use the Scorpion's diff case cover in the beta trans?

      Thanks,
      Ralph

      That's pretty much exactly what I did. But you have to use a ring gear that matches the drive gear in the gearbox so I bolted the VX ring gear to the Scorpion differential and used the Scorpion cover.

      I looked at the instructions for adjusting pre-load and determined it was voodoo magic so I just went with it all the way it was.

      Never had a problem.

      What about a ring gear from a different trans but same ratio?

      You mean same as the box you're installing it in? I'd think it would work but I'd check it. Fit it all up together and see it everything turns OK without binding.

      Yes, the diff from the Scorpion transmission has the same ratio as the 1982 Zagato transmission. Maybe I'll swap the ring gear just to be sure.. Thanks again.

      Thanks DJ for the help. I installed the gearbox last weekend and everything works as it should. I have a meet this weekend then its time for the FI conversion.
