Catastrophic Belt Failure

I would think most people understand that the adjusters are not there to hold the transmission in place. They are only there for fine tuning alinement and once that is accomplished the upper and lower fixing points are what hold it. The belt I just changed on my bike after 13 years looks fine and putting on the new belt didn't require any adjusting at all just slipped right on. When I installed the dual adjuster I set it up going in the same direction as the other side. All of the setup was done with the inner primary removed, which made it very easy to get to. But I still think even a road bike should have it done correctly. IMHO Thanks again for your input, Chuck.

Whilst I agree with you in principle with what you say in practice it's a different matter
Twice on my commando with belt drive the top gear box bolt came loose but the twin adjusters held the gearbox in place no problem
And would you run your commando without the woodruff key on the crank pulley ?
After all it's only there to index the alternator rotor it's the taper that takes the load
 
If anything the dual adjusters make it easier to... adjust. Remember you are trying to get the crank and main shaft parallel. Fine tuning with a screw adjuster is a lot easier that with an adjuster just on one side.
 
Don't really know what your point is?? That your gearbox bolts have come undone twice and you had to count on your adjusters to save you?? LOL

The point is that with the dual adjusters is they are easier to dial in and then you tighten down the gearbox bolts. Not sure what you are missing.
 
I was replying to Baz, I have no problem with my belt. I put my adjusters on in the same direction as I feel it makes better sense. Once you set it up it should be a set it and forget type thing. My new belt is tracking just like the old belt.

On my other bike the belt has been perfect since sorted. But just about everything on that bike is refreshed.

You always have to assume that modifications to a well used bike can be a challenge. They will definitely expose any weaknesses.

Yes I agree luckily the twin adjusters did save me
In the end it turned out to be the maney outrigger I was running at the time
It must have been causing some resonance or something? Since I removed it the gearbox top bolt has remained tight
So my point is even with a loose top gearbox bolt the belt still tracked fine relying on the two adjusters LOL
