Airwolfie,
I just came across your rebuild thread since I am ready to embark on mine. One thing I noticed is the position of the Shift Fork Guide Bar relative to the Stopper or Selector Plate.
On my '76, the Starwheel end of the Bar is notched. The end of the Selector Plate fits into this notch, which brings the Bar out a little bit. You can see in one of my Album images the impression on the Selector Plate where it has rested in the bar notch.
The end of your Selector Plate is positioned in front of the bar and the bar is recessed into the engine more than it should be (I'm thinking). The 1st & 2nd Attached Thumbnail images are yours, the 3rd Thumbnail is an image of my mechanism.
The 4th Attached Thumbnail shows where the Stopper (Selector) Plate has fit into the notch in the Shift Fork Guide Bar. 5th Thumbnail is the Starwheel end of the Shaft where the notch is.
Take a look at the images of my Gear Selector Mechanism Album (link below), specifically Image #'s 3, 9, 16, 19 and 61.

Perhaps there was a design change that I don't have in my '76.
Hope this helps!
Thanks YL, ...I'm guessing this SHOULD be like you described, otherwise they would not have bothered with the notch!! Oil feed is important, so I will do this.........
From the pics of later models, and reports of eliminated plug in later parts manuals, it appears that Yamaha elected to weld that area...
That clears it up for me. Mine is welded up as shown in one of the linked threads (see image courtesy of DeadChef), so I will stop looking for a lost plug and trying to find a replacement to order...
Thanks, TwoMany*** !!
Well Airwolfie I sure hope it aint no big deal for You Sir.
I'll do my good luck dance around the ole fire fer Ya.
not if it comes off in one piece.
If it was mine it probably would not come off in one piece.
I use sealer on every thing
I'll do my good luck dance around the ole fire fer Ya.
Airwolfie ....ya fecked now for sure
Did ya get this sorted yet ?
If your crankcase hasn't got the hole plugged already with weld you'll need to plug it with something ...preferably the correct aluminium plug but as its a metric hole you should have no difficulty finding something suitable to drift in there.
if its open then you'll be able to remove the selector drum retaining plate and drift the selector fork bar back out a fraction to the correct position for the locating tab to sit in the cut out before you plug the crankcase the other side.
good luck matey
Hehe I was trying to be nice to Carbon, but you gone and done it!
If I pull it out a smidge, is there any way of knowing that it's plugged or not?
