Looks like I need to pull my alternator from my GW GL1500, and rebuild. Most likely new brushes.
I have no power coming from the alternator. It use to start working after the bike started, then after it warmed up. Now, nothing.
I've been reading about the how-to on the GW.
Seems they don't have too much trouble in putting the alternator back into the engine. They align the rubber dampeners so it is at a vertical/horizontal position. Alternator goes in, within minutes.
For those who have done the Valkyrie replacement, have you also aligned the dampeners, before replacing the alternator, or did you just try to replace it?

If you line up the blades with the spaces they fit into it goes in easier

I simply left the vanes on the engine where they were when the alternator came out. I put a dab of grease on the rubber dampeners to hold them tight to their respective vane on the motor. I had watched carefully how the alternator came out and I mirrored the angle of attack when reinstalling it. Given the limited clearance I couldn't get the alternator vanes to interlock into the dampeners completely so I installed a couple of alternator bolts and gently pulled the alternator into place with a little "pop" when it interlocked properly. I guess it's just one of those things that either gives you fits or not.

The "pop" you heard might have been one (or more) of the connector bands that hold the dampeners together snapping. Its best to take look inside, align the blades and slide it in without forcing it.

The "pop" you heard might have been one (or more) of the connector bands that hold the dampeners together snapping. Its best to take look inside, align the blades and slide it in without forcing it.  I can see how one might think that. I had a pretty good visual alignment of the vanes so there's no chance that that happened. The sound was simply the alternator vane popping into place between the dampeners. I'll tell you what happens. The dampeners in the upper quadrants of the circle tend to move down toward the center of the hub. The grease that's applied is an attempt to stop this from happening. However, the jostling that occurs while fitting the alternator into the tight space can allow (or bump) one or two of the dampeners down toward the hub. The slots between the upper dampeners are now too small for the alternator vanes to easily fit. Using the bolts to pull the alternator into place pushes the dampeners apart and outwards until the vanes can slide into place. Actually there's so little room in the cavity that there's no way the alternator and dampeners are going to go into place incorrectly. It would turn into a major mash-up it one tried.

I've only been in on one alternator replacement... we used grease too.
Since then, I've been imagining using a little dab of RTV to glue them in place for the install.
Not so little that it doesn't work, not so much that it causes a problem...
Won't know till later if it is a good idea...

I'll be doing one later on this winter and might try your " dab of RTV" idea. If I do, I'll let you know!

And what happens when that rtv breaks loose and gets into the oil pump. or the clutch scavage pump. I can see it now, blown engine.

exactly what I was thinking. I have done a few alternators, never needed any goop to hold them things. Sometimes we make things harder than they are just by thinking its REALLY hard, a little concentration goes a long way...work smarter not harder

Tell me more about that clutch scavage pump, didn't know we had such a thing. What does it do?

All a useful discussion. My original post was more about there not being an issue with regards to remounting an alternator into a GW engine, where in a Valkyrie there has been some lively discussion on it.
On the GW, there is the additional step of aligning the mount vertical/horizontal. I do not recall this being said for the Valkyrie at all.
I understand that there may be more room in the GW frame than the Valkyrie (not that there seems to be in the videos I've watched). I'll find out soon enough myself, as it looks like I need to rebuild my GW alt. I was just going to swap my IS alt into the GW, but they both have close to the same mileage anyways, so I would want to rebuild it first.

I watched a youtube of a 1500 wing alternator removal today... it seemed like he took out three bolts, wiggled the alternator loose and just pulled it out.
I've heard of people (Mac, maybe) who can wiggle a Valkyrie alternator right out, but it took a lot of patience when we got Stanley Steamer's in and out.

Buy new dampeners. They are relatively cheap and seem to stay put easier than the old, oil soaked ones. That is what I did. Hay  Jimmyt

Very good point! Note: I had Yamabond in mind ... just a very small film in the same fashion as when assembling crankcases.

yeah, but once that alternator is spinning that yama bond is going to break loose. unlike when you put it on gaskets and engine blocks there are no moving parts to break it loose.

1/2 hr to remove battery, take some pictures, remove the 3 alt bolts (one was corroded), pry it out, move the leads and the drool tube, unfasten the leads, and remove the alternator from the bike.
Now time to tear it apart, and inspect/rebuild it.
If I have any trouble, I'll reclock my IS alternator and install it back in.

I was originally going to rebuild my Valk alt, and then swap it out in my GW. Then rebuild the GW and hang onto it as a spare. But with the GW crapping out, it's changed things. There are also no parts available locally, so I need to order and wait. I've decided to swap out the GW alt for the Valk one, rebuild the GW, and order an extra set of brushes for the Valk alt, and swap them again and replace the brushes in the Valk alt. It's been mentioned about buying a GW alt for the Valk, and reclocking. I'm sure everyone will figure out what needs to be done, since they'll have an alt of each kind in front of them, but here are some pictures to show you the comparison. Valk on the left, GW on the right with the capacitors.     Since I'm putting the Valk alt in the GW, do I need to clock it? The cable is longer to reach the lug which is clocked 1/3 further from the battery, so why can't I just leave it where it is, and now have a cable that isn't being pulled? I did loosen it when I removed the alternator from the GW, but I could have just as easily done it after I removed the alt from the engine/frame, like I did with the little box that was connected to the alt?

Don't shortcut, set the alternators side by side, remove the screws, rotate the head so that the GW body parts are in identical position to the Valkyrie or vice versa. Reinstall the screws and you are good to go.

After prying my Valk alt apart, breaking the 3 leads from the windings, I didn't like the instructions very good at all.
I then took apart my GW alt properly this time, and inspected. Found the brushes stuck in their slots. Used WD40 to flush it out and get them working again, put it back together. I put it back into the GW in 5 minutes!
I do need to replace the brushes, but they can wait.
I now need to try to unwind some of the winding from the Valk alt, and resolder it into the housing. If this works, then I can get it working again. I'll replace the brushes, and have one on the shelf for a spare. If not, I'll look for an inexpensive replacement.

OK,
I'm missing something here
I have the alternator out to about an 1/8" and can't seem to find the last 1/8" clearance I need to get the alternator out. If I can't get the OEM one out how in the heck am I ever gonna get the new one in?
I've read every article I can find on here and CLYMER's until I'm blue.....I'd rather be riding!
TIA!

There's a way. You don't have to cut the frame  ... with patience, and if you hold your mouth right, you'll find that one way to "twist" it out. Hopefully you'll be paying attention and not just thrashing, because that's the same motion that will get it back in. There's some wires on the back, maybe remove them first. It might help to get the center cover out of the way, maybe just loosened and moved some. Maybe put some painter's tape on the center cover to keep from scratching it. Careful with the center cover, it looks like it is made from plastic, but it is really made from unobtainium ($), and it is in there tight like the alternator. -Mike

Everything Mike said patience is required. I pushed the back end of the Alt. into the opening towards the center post and let that end drop down. Then slowly twisted as I pulled the front end up and out. I couldn't believe the ease it came out. I stopped right there and tried to remember every twist and turn I made for the replacement later. When I installed it I actually stuck the back end of the Alt. in aiming for the cavity (small) in front of the frames center post. Took me longer to install I didn't remember every move I made on the removal.

I just put mine back in today. Sorry to say, but it was a piece of cake compared to the u-joint boot.  I put all new rubber dampners in it while i had it pulled apart. They hold themselves in place so all I needed was a good small flashlight to get everything lined up and it went in with no trouble at all. First time I had ever done it. If I can do it and call it easy..... and not break anything....... then it is definitely easy for the average guy.

If you remove the capacitor on the back of the alternator the install
is much easier. Moving the center cover out of the way also helps.
