Hi all, it's getting close to the time to replace the alternator belt (50,000km) has anyone done one of these yet and if so are any special tools required?
 
Never mind my earlier comment John. I had no idea we even had an alternator belt. I see it now in my maintenance schedule. A first for me.

I haven't done it, but there is a belt tensioner tool (Part #020677Y) required according to the Service Station Manual see image below.

C1400 Belt Tensioner
 
Sorry everyone my laptop went down shortly after I posted that, thank for your replies. I've also found out that the factory service manual says to drop the engine to remove the cover, hopefully there is a short cut to get around that :(

Yikes - let's hope so, otherwise I imagine that amounts to quite an expensive belt change if you have to book it in with a dealer.

When it will be done, let us know how long it takes.
 
No shortcut, these are NOT the engineers from the 60-80's. It's made like a goldwing frame, it all comes off in front of the cover and on top. All the coolers, motor mount, etc, you need to access the alternator and surrounding area also. The consumer wanted all this junk on a motorcycle, now pay the wrench fixing it!! I'd love to see a shortcut, I've tried. 3+ hrs minimum if you have done a Cali before, if not GOOD LUCK.
I copied the belt tool, easy if you have a welder & shop tools. Cost 20 bucks.
If you are a patient wrench to do it yourself, it's not a bad way to spend an afternoon. PIA=yes , especially the lock bolt for adj.

Awww... shit, and there's even more crap in front of the engine on Euro 4 bikes

I guess this is Guzzi's way of leading you gently, step by step, towards a complete engine rebuild

Step 3 of 10 - Alternator Belt replacement
Step 4 of 10 - Cylinder head replacement
Step 5 of 10 - Transmission removal and clutch replacement

What is it they say....."Moto Guzzi: Making mechanics out of riders since 1921."

Guess I'll pay a wrench for this job when it's time comes

I have booked it in to morrow with my local Guzzi guru mechanic, he says it is still a pain in the arse but he has done it before without removing the engine mounts. I will see what I can find out.
 
I read on the Wildguzzi Forum that an owner in Phoenix had cut through the alternator cover to remove a broken belt, and then replace it. Apparently the cut was barely visible. I haven't studied the setup on my Touring, but as I close in on 50,000km, I will be studying this approach carefully.

Let us know when it's done with pictures please.

Sorry guys no pictures, I had to drop the bike off before I went to work. He managed to replace it by undoing the cover and then cable-tying the cover to the frame. He says it doesn't leave much room to work with and is a complete bitch of a job but it saves having to actually get the cover out of the frame. He did some other work for me at the same time, total cost for labour was for 3 hours, the belt took approximately 2 hours. A good mechanic is worth his weight in gold.
 
Interesting, has anyone gone passed the 50k mark and not done the job? If so what happened? Thanks
I had a BMW, 2005 they had the same belt and I was replacing them every 50k . The belt was like new not crack nothing, it was probably good for another 50k. But would you take a chance....

...and I bet it was a lot easier, cheaper and quicker to replace than the Guzzi. My wife had a 15 year old mini when she was a student 30 years ago and her alternator belt broke shortly after she moved into student digs. I replaced it for her and that was the start of a beautiful relationship that is still ongoing today (the wife, not the mini).

Usually a broken alternator belt doesn't cause any damage, but leaves you running on battery for a while. If you're lucky you can make it home or somewhere safe, but in the middle of nowhere, don't count on it.
