More Woes By Gti (Read 726 times)

For some odd reason my magneto and woodruff key become enemy's and fight against one another. I have had the magneto sheer off or warp the woodruff key to the point where the magneto will rotate itself loose and distort the slot that the woodruff key goes in. I put lock tite on the nut for the magneto and muscle and it still walks loose. I am at the point where I do not know what to do to fix the slot the key goes into so I can get moving again. Am I doing something wrong or do I need to get another crank to fix this issue.

GTI,
the FLYWHEEL locks onto the Woodruff key to keep it in the right timing position. Now let me ask this the NUT that holds the FLYWHEEL onto the shaft WHICH way does it TIGHTEN?

When you put the Flywheel on does it go all the way in? Can you take some pictures of the Slot on the Crank is that damaged or just the FLYWHEEL SLOT or both.

I'll take some pics in a little bit.

MAN OH MAN, you are the unluckiest guy I have ever heard of. Nothing and I mean nothing you have worked on that scoot has gone right. You need TONS of MOJO Bro.
But we will help all we can to hopefully get that scoot of yours finally running at least half way descent.

McCray's Law says if it is going to happen it is going to happen to me. I have learned to roll with the punches learn from my mistakes and not be afraid to try new things when old things don't seem to want to work. The problem is that I do not have the world quit in my vocab.

Here is a pic of the slot for the key for the magneto. The magneto was fine but the crank, well we will see.

ok does the key fit tight in the keyway if so then you may need to put a washer or two on the end of the crank then thighten it down with an impact

Well I can see it put a HURT on the CRANKSHAFT SLOT(OUCH). How in the hell did that ever happen??? The Flywheel nut must have come loose for that to happen. You can try and put a new woodruff key and put the flywheel on and put a LOCK WASHER then the NUT and put it on with an IMPATCH WRENCH and see if that will hold it. If not sorry to say but it will cost you a new crank, tearing down the whole engine again(MAN-O-MAN).

That is exactly what I was thinking Alley but I had THOUGHT that maybe a little JB Weld would help. It seems as though it may be a lose, lose situation either way. When I put the washer and hut on it I hit it with the impact and them put muscle on it and it still worded itself loose. I do not want to tear down but I am willing to do this again if I have to.

one other thing that could cause this is the tapper of the crank and the tapper in the flywheel not being the same the easiest way to check is to measure the big end and little end of the tapper of both the flywheel and crank and measure the distance between the ends of the tapper if they dint match then it will continue to work lose
