Yamaha Shift Shaft (Again)

[Geekie1]

Your 2nd picture shows the break away and the exposed corrosion. Is that the only broken bolt that is exposed? The corrosion looks like aluminum oxide. I have heard that straight chlorine bleach dissolves aluminum oxide. I would hit that corrosion with bleach to dissolve it. If all the bolts are indeed cut, that exposed bolt with aluminum oxide corrosion may be all that is holding it.

My favorite tool!

Thanks guys...

Yep, I have drilled completely through the bolts. I can see the outline of the shank in each hole and you can just "feel" when the bit stops chewing on the SS and bites into straight aluminum.

And now that you mention it I think I remember hearing about bleach on AlOx. I ventured into the forbidden sector (laundry area) to look for some but I found about 12 different scented fabric safe whiteners and brighteners and whatnot but nothing look or smelled like real bleach. I'm stopping to get some on the way home.

There are precious few palces where you can gain leverage to pry on the head. The damn lower cowl is flimsy and in the way of everything. It's working against me like one of those cones you put on your dog so he can't chew his a$$.

So hopefully next weekend I'll be able to hook it to a trolley hoist and apply lots of heat and pry and my BFH. Well every time I get out my BFH bad things usually happen...

yes yamaha's have that dumb design with the solid cown that omd did away with a long time ago. with a hoist and heat you will start to see it seperate and you'll be able to slide a prybar into there.

Before you go cutting with a sawzall, I would get a GOOD 1/4" die grinder and a carbide bit and go in and relieve the housing around the broken bolts. You should be able to use a 2" long cutting bit and go in there and remove some of the aluminum and relieve some of the pressure locking those bolts in there. It looks like your going to have to replace the adapter anyways, so at this point why not just cut her up and make less work for yourself.
