Change that Belt

I have been following the saga of a rider on the road with a broken alternator belt, by the time he got going again it must have cost hundreds of dollars.

IMHO ITSec gives good advice on how often to change, I will swap mine out before I take another long trip and carry the original as a spare.

Quoting ITSec from another thread
The belt should be changed every 3-4 years (based on age) or at about 40,000 miles. Remember that it's in a fairly harsh environment, with fumes, heat, etc. In fact, the only thing it isn't exposed to is ultraviolet! The factory belt is not too outrageous, and the following belts are all very close relatives (some fit slightly better than others):

Alternative to the Guzzi belt is a Gates 4PK740, as well as the following:

Bando            Dayco           Gates           Napa                  Goodyear   Cadna   Pix
4PK740      5040290        K040292      25-K040292            4040290   290K4   291K4

Belt is used in 94 Subaru Justy for alternator with no A/C
End of quote

Another part No from Pete Roper is K040292 (I think this is an auto part No)
The Bando 4PK750 will also fit
The Guzzi part No is Moto Guzzi 05702530

I wonder if the 1400 uses the same belt?

I changed my G11 belt @ 50,000 miles and 10 years. It looked like it could have gone another 25,000.

Which IS the Gates belt. Available from the bay of fleas locally for forty odd bucks.

LATE MAIL - just purchased one for 44.07 pacific pesos...

take care

'Local' Gentlemen, I just got a Guzzi one from Mario for 29.95...
with a few other little rubbery things, shipping was 16 scheckles...

G'day Pat
Greetings from Tas ...hope all is going well with your move to the north island ...
Your right of course, sometimes we think that prices are more expensive 'local' ...
I suppose it's a case of always 'buyer beware' and check your prices ..
Stay warm and safe

Cheers Trev,
I'm the worst at spending hours researching the thing I can get down the road  

Yeah things are good up here near Byron Bay...
I do miss the endless great roads down there however - and the apparent lack of Mr Plod!!
Bright side (?) is I do get to ride and hang with some of these strange northerners on a semi regular basis.    

Staying warm is a priority right now, currently off the coast near St Helens, due to dock in Triabunna, tomorrow morning!!
Fortunately I have a pressurised aluminium tube to hurtle me back towards the sun.

Give my regards to the boys and girls at Pier One Sundays.
Pat

EDIT: oops, that ran off topic

I changed my belt over the weekend. Although I was in the comfort of the garage I deliberately restricted myself to the tools I normally carry on the bike.
Allen Keys, 4,5 & 6mm (these have a ball end but it's just a nice to have)
Ring/Open end wrench 13mm, a small adjustable would do at a pinch.

Remove bottom 4 cover screws
Remove ECU cover and ECU holding bolts, swing it out of the way.
Remove the 5th cover screw and the breather box standoff which also acts as a cover screw.
Loosen the 6mm clamping screw at about 11 o'clock with regard to the alternator pulley.
Remove the cheek from the right hand side of tank
Loosen the locknut on the belt adjuster, easily accessed once the cheek is out of the way.
Back off the belt adjuster until at least 1/2" of thread is exposed
Squeeze the belt together so the alternator swings down, if the belt is broken lever the alternator down

Place new belt around alternator pulley, start it around crank pulley
Turn the crank with a wrench or crank it with the starter and the belt will pop on.
Re-tighten the belt tensioner and the locknut. I just put it back where it was but also noted it was easy to twist the belt through 90° in between pulleys. It should also be possible to turn the motor over using a small wrench on the alternator pulley nut, a little slip would be ok.
Re-tighten the 6mm Allen clamp screw
Refit cover
Bolt back the ECU and cover.

The original belt at 40,000 km has a few small stones embedded in it probably from the Dempster trip but still has plenty of life left, I will carry it as a spare.

I probably missed a step or two, I will review the notes I made this evening\

It's much easier to access the adjuster if you remove the right tank cheek

Back the screw off at least 1/2" (15mm)

Good heads up Roy-many thanks

Put my new belt on last week (the Gates unit). If anything, it is a tad large, as the adjustment/tension screw is nearly all the way in. However, these belts really do not stretch (in my experience) so should be all good for another 60,000 km. Had genuine belts for the last two.

I will hit 120,000 km in the next few weeks. When I get back from the Ragged Fringe Rally, I will do the rest of the service bits. Must order some oil filters...
