I have a 2002 GL 1800 with a motor that is knocking very badly. My question is: Will a motor from a 2010 Gl 1800 work in my 2002 GL 1800?

I know a 2012 frame will fit on an 02 engine, done that. You sure it wouldn't be more economical to fix your 02 engine...how about some details on the failure?

Have you researched the alternator drive failures. They make an awful noise. They typically get quite when the rpms are increased. Here is a link that demonstrates how one sounds that has failed.

Oddly enough, the ENGINE actually sounds good. That rattle is not the power plant, IMO. jimsjinx

OK. Here is the story:
I recieved a call from a guy asking me if i would put his 2002 GL1800 back together again. He siad he over reved it and took out the alternator drive. He took it to a local Honda dealer and they tore it apart. They rebuilt the clutch. Why I don't know. after sitting there over a year still all apart the owner went down and gathered it up. He took it to his garage and had one of his mechanics put a new alternator drives in and put the motor back together again. It set for two more years until he called me. I told him to bring it up. Which he did. We started on it but got busy and had to set it aside. I've had it for almost a year. This week we worked on it and got it running. It started Knocking right away. After about 1 minute it stalled and the starter would barely turn the motor over. After letting it set a few minutes it started and I let it idle it did the same thing. It seems to me like it spun a rod bearing because the motor is getting tight.
The sound is very much like that in the video but it has a new alternator drive.

Well I would think that if a 2002 engine will fit a 2012 frame, there's your answer....Is this going to be your Wing or your buddies???....If its yours tear the engine back down sell the heads etc, make a little to help on the price of a newer engine....

To me that video does not sound like a rod or bearing knock at all. A rod or crank bearing failure will result in a very even knocking sound which increases with engine speed. The noise in that video is very erratic and not really a knock at all, more of a grinding, crunching sound. A bearing knock will be a lot like a valve tappet tick, but much louder and lower in tone. It will sound like a hammer hitting something inside the engine, and will be very even and regular.

Since an 1800 engine is computer controlled, doesn't it have a rev limiter?

JerryH you are correct! to you and me it doesn't sound a bit like an engine problem at all, it most definately sounds like an auxiliary noise, especially when the guy revs it up! But I can understand a 1800 owner with little or no mechanical knowledge getting all paranoid over it and placing it in the hands of bloodsucker with equal experience.
Personally, I just think they're lucky that the goldwing has morphed long enough for Honda to realize you ought to be able to change out your alternator without pulling the motor.

Please read the thread.:readit:
The video is not of the bike in question.

Thank you Ken,
The motor is definatly getting tight to turn over. I don't think the alternator drive would do that.

That's a bummer, BMS. I was kinda wondering about the ADG when I asked for details. The few ADG's I've replaced have all shed some chunks into the rear engine cover/crankcase area. Luckily I've always been able to account for all the 'floaters'. Maybe a chunk from your old ADG found it's way to a bad place?

When I recieved the motor it was repaired and put back together. I had no part in replacing the alternaton drive. But I did see the old drive.
What causes the ADG to go out? The owner said he was showing off to a harley guy and he reved it hard and it started knocking. Thats all I know.

The 2010 engine will fit. A chap over here busted his 03 engine on a kerb. He was lucky enough to find a 2010 engine from a crashed GL1800 about 150 miles away. He also took the 2010 alternator as they are higher output. The earlier alternator will spin to death in a 2006 and later model.

Blame it on the part itself...it's likely it was ready to fail and the owner just helped it along. It was a known issue on early 1800s. The fix (replace the part) was reliable to my knowledge.
