My 68/69 was hinged along the rh side when I got it.  Seems right to me, though mine wouldn't be able to tilt forward because the engine/carb would be in the way.

Ok, yesterday the '63 RD-8 drove out of barn,not to far though, it seems the chain is jumping the top sprocket. I have the chain tensior bolt screwed all the way and it still loose. Chain tensioner does push the chain into the center of case does it not? Thanks for any thoughts , hotdoo

Are you sure the chain is jumping and not the front axel sprockets jumping the track windows?  Loose track?

I don't have a 63 to compare to, but if it's anything like the 68 style the top sprocket is held within an oblong aluminum block.  The bolt just holds it in place.  To tighten the chain you have to rotate the aluminum block after loosening that bolt.  This is assuming there is a slot for the bolt to move back and forth within.  I could be wrong but that's what I envision to tighten the chain.

As you likely already know the earlier alpines were definitely different in this regard.  I looked up a 66 secondary which is likely closer than what I talked about.  As far as the tensioning bolt its hard to say from the picture if that little idler sprocket makes the chain tighter or looser from screwing it in.  But if you hadnt seen this before thought it might help you understand whats inside.

Well, that case doesn't have a concentric to it, all it has is the idler to push into chain to take up lack, I put a little longer bolt in it but I still need a longer all -threaded bolt. hotdoo

Maybe the piece that has the female threads is stripped?

No It's not stripped, I even took the adjuster nut,part number 15 off the bolt so I could get more length. I thought I matched up old chain to new chain perfectly but needless to say I f--up somewhere,hotdoo
