Any ideas on how to repair aluminum speedo casting?
« on: July 17, 2009, 09:55:15 PM »
Okay, so I got in a hurry trying to do some things before the sun went down (even though I was under a light) and I would up breaking the little aluminum casting that holds the speedo cable into the valve cover.   It broke into three pieces, one of which is still in the motor and is still holding the oil seal in place.   The other two pieces are pretty clean breaks.   
So I cleaned them up and JB welded them into place, after a day of curing, they easily fell apart.   
Much profanity ensued.
SO I cleaned the JB Weld off and superglued the whole thing (The speedo still turns ;D) and let it go at that.

The thing is, I don't want to be riding and have those parts rattle off (I know they will), leaving me with a speedo cable flailing wildly around the front tire/hot exhaust area.   So what can I do to fix this thing any better short of pulling off the valve cover and fitting another housing?

Any super duper aluminum epoxies out there?   Would it actually be awful if I just RTV'd the crap out of it?   

Oh know, now I'm thinking like the previous owner!

Are you talking TACH drive hole in Valvecover on Engine?
 or, Speedo Drive on Wheel ?

 short of hitting them with a big hammer, I cant imagine a way of breaking  either..

 When I go take some pics this weekend, you can have the one from the gutted engine if I can find it. You pay the shipping hassle!
 Curious how you broke it, though.

Get used to not having a tach...

 Only way to swap the cover is to either cut your frame, or pull the engine.. :o... unless it is a Hondamatic..

Alumiweld might be good for fixing something like this.

Not using a BIG ^*^%ing Hammer, might prevent such things..
