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.
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.
