Today's mystery object.

[UncleD]

Started my 1958 Super Rocket today and this fell out (from around the centre stand area).

Any ideas?

My guess is it's from your battery carrier...

Hi UncleD.

It could possibly be the oil tank clamp bolt.

Uncle D.... Have a good look around that battery carrier. Two bolts, a top battery strap and two battery side straps should be there, as  nicely pictured above The bit that fell off looks like the upper plain pin 42-4505 from the top strap. The retaining bolts 24 7343 pass through into the lower threaded pins 42 4506.  Easy to fabricate if you find the cupboard bare.

  Give the oil tank a waggle in case I am wrong!

I did top up the battery amongst other things during a fortnight of fiddling so reckon you're spot n...shame I put the seat back on this afternoon!

How is this for typical?  After working on carby, brakes, sump, head steady, dynamo chain (all with unexpected dramas), I fired her up and the headlight fell out and broke on the mudguard.  To be honest, between the S/R and issues timing my Harley, this did not surprise me at all!  I just calmly said.."bloody typical" and got another beer.

I must say though, i took her (S/R) for a spin this afternoon and was blown away by how quick she is.  She has a lager carb (389) and I've just changed up to a 107 needle and 320 main but I can't believe this is the the sole cause.  I'm hoping I've struck it lucky and whoever had it previously has fitted some goodies inside..I will hold on to this nice thought until the next thing breaks.

Thanks to all for your support and ideas.

Uncle D.....Talk about Sod's Law.....Fix the motor......electrics fail....fix electrics.......repeat.....

  From hard won experience, use Loctite on every fastening. It obviously keeps things in place, but will also lessen the corrosion between threads making dismantling that bit easier next time. Maybe head Bolts would be the only exception.
 
  Warming a loctited part with a hot air gun softens it enough if it is a bit too difficult to undo simply by hand.

 Nice to know you are back on the road....Just be careful, travelling at warp factor 6. Wear the cloak of invisibility in your mind and anticipate no one has seen you and they are likely to pull out in front of you. This mindset has worked for me  since I first took to the road on my first push bike.

I reckon a squashed battery strap to be found......

I would say, don't ride it again until you fix it, especially if you have a refillable acid battery. I once had my carrier come apart and the acid splashed out marring some nice new chrome, not to mention losing original '55 battery carrier parts. Now I use only permanently sealed gel-filled batteries. Nevertheless, I tie all the carrier parts together and to the frame with tie wraps.

He knows his trunnions that boy!

Battery strap it was...all fixed.

Where I live there are very few corners and no hills so speed is everything!
