Alternator Bolt Housing broken :(

Post by redboy » Thu Jan 04, 2018 7:26 am



Hi All - got a nice piece of bling for the bike for Christmas and needed to remove the alternator. The bolt at the top was stuck so I started to drill it out to replace but the housing has sheared off!!
I'm not sure if this could be TIG welded or if I'm going to need to get the engine out and replace the the whole back cover.
Suggestions/cures anything please!!

If the area is accessible and the broken part is not broken through a area that exposes a internal engine part it may be possible.
I'd take several detailed pictures and go to a welder and have them look at it.
If it's done on the bike,you must remove the battery and I'd hope the welder would take all other precautions involved.
On bike welding is not for the casual welder.Welder grounding,spark shielding,fire control methods have to be considered.

The piece that has broken does not expose any internal parts or workings - its just the outside of the bolt housing. I'm going to try some metal epoxy resin first - otherwise it looks as if its going to cost me £200 + for a new housing :(

Personally don't bother with epoxy.It won't handle the heat.It will look good but no strength.Post a few pictures..We may be able to come up with an alternative.

I would ask for the same thing, add some pictures then we can comment better. There was a similar issue last year, so we can compare it with yours.

I realize you’re in the UK but how about eBay? I got one for about $40 on eBay. In very good shape. But what ever you do, removing the rear case is a pain. I’m starting next week to put it back together

Good luck

Good suggestion! Or maybe google to see if any bike salvage yards are near you.

Sill waiting for the JB Weld to arrive hoping it will do the trick. I've also sourced someone who's a TIG Welder if it fails!!

If you glue it back on put some tape over it..It might keep you from loosing it on the road when it falls off.
Or just weld it back on.

My opinion only, Put the 2 other bolts in and ride, keep an eye on it to be sure it is not coming loose or the other 2 bolts coming loose, I'am betting you could ride for a million miles with only 2 bolts, But be sure to keep an eye on it, if it keeps coming loose, then pursue other options, Been a mechanic for 30 yrs, and see this kind of stuff all the time, although i do not pull wrenches any more iam now a maintenance manager at a large facility

I was thinking the same thing. No way J-B Weld is going to hold that thing in place once the bolt is tightened. Bold threads exert an amazing amount of force, and when that force is applied in shear against the J-B Weld...it's going to come off right away.

Might was well skip that process and just get it welded. :)

That is an extremely easy TIG weld to repair. Just needs to be prepped right before welding. You are lucky that it is at a place you can get at!
