      Its sorta ugly but it’s a 100% complete Javelin.
      The pivot on this motor seems unreasonably loose, I tightened the tension screw and that did not stiffen it up near enough. Note in the picture on the stand, it will not stay in between full pivot either direction, always to one side. Also, when off the stand, the whole pivot & clamp assembly slides up and down the pivot about 3/8″ which I’ve never seen before.

      Has anyone else had a motor with these “symptoms” or know what could cause this?

      I haven’t torn it apart yet but I’m guessing something is very worn out, the pivot looks heavily greased so hopefully none of the surfaces are worn out.

      Luckily, according to the serial number I should be in the clear from the bad crank seal, but it’ll get a thorough tune up this spring. Maybe a paint job if I feel up to it.

      Thanks,
      RJ

        Around here, the problem is just the opposite–too tight. But anyhoo, the friction screw #92 pushes on the brass plate #90, which pushes on the rubber pad #91, which squeezes the split bushing #89 which tightens onto the pivot shaft.

        Expect the rubber pad to be all mooshed out.

        Terminology mine.

          I had the same loose steering tension on my 56 Johnson 30hp and as Frank noted, the rubber pad was worn out. Not sure about the vertical movement you have unless the pilot shaft or swivel bracket is severely worn or maybe a missing or broken thrust washer. Nice motor – good luck with the restoration. Chrome is in very good shape.

            Can’t say that I’ve ever paid any attention to the vertical movement if there was any.

            BTW, you can cheat and simply use a slightly longer #92 screw. I suppose it might affect the cushioning or something.

              Frank and Bob, thanks for the input, makes sense that the 65 year old rubber is no good.

              I’ve got a few of these big twins and this is the only one I’ve noticed the excessive vertical movement on. I’ll update this forum when I figure out what caused it.

                Unless you are going to put a tiller on it, you shouldn’t need any tension in the steering once the steering wheel is rigged to it. The friction throughout the steering rigging should be enough.

                Yes – it looks a bit faded and rough, but the chrome looks good for that model!
