So i'm going to at least tighten it to where it's almost as tight as triumph recommends, but not cold. I'll set it like that when hot.
Das: Ya never mentioned the belt shredding.That in itself is a BIG problem and the stealer should have been on top of that.Too tight or too loose should not cause that to happen.SO! If it were me,I'd be lookin real close at the outer edges of both the front and rear cogs for jagged edges on either side, and on the teeth in the cogs,also for jagged edges on the ends of em where the belt rides.I'd also check both cogs to make sure they're tight and not warped.

The outer edge of the front cog has a machined surface,not real smooth,but it shouldn't be chewin up the belt either.The inside edge has nothin.The rear wheel alignment is what keeps the belt from traveling off the inner edge of that front cog.

The outer edge of the rear cog also has a machined surface,but again,shouldn't be chewin up the belt.The inner edge has a smooth chromed thrust ring which is replaceable.So I'd be lookin at all those things real close and ASAP.Let me know what ya find.Now ya really got me curious. lol OK?? Dave!!

It wasn't doing this till the belt was loose after changing the tire. And the alignment is dead on where it was before that, so i gotta think it's the looseness. i adjusted it tighter last nite...not as tight as triumph says, but tighter than it was.

Daz: Just how loose was your belt??? When I say I adjust mine alittle on the loose side,I'm only talkin an 1/8 inch or so more then spec or what the SM says,and that's at the belt's tightest point and COLD,NOT HOT,and my belt has been fine.Now if the belt was real,REAL loose,I suppose it's possible that it could sustain damage,but that's what that thrust ring is supposed to prevent,unless the belt was so loose that it actually jumped that thrust ring.Then I could see it shredding.It's too bad ya didn't live close by.I'd have ya bring it over and we'd straighten it out or I'd know the reason why.But I would still check for jagged edges on both cogs as well as making sure they're not loose or warped.Keep us posted as you now have my undivided attention.What I'm lookin for here is the "WHY" this happened.Somethin else I just thought of too:Is the wheel itself tight when mounted on the machine?? In other words is there any side play in the wheel which would suggest a bad bearing??? Dave!!!

You said yours was 2" at the loosest. Then later you said that was total both ways, IE: up AND down. So i assumed yours was extermely loose because even after you said both ways meaning it would then be 1", thats still 4 times as loose as triumphs spec assuming you use 10 Lbs of push. Mine was probably 1-1/4 to 1-1/2 when cold and about 1/2 that hot. That with 10 lbs tho. I hve a scale which i can push with my finger to get a feeling of what 10 Lbs is, so while not accurate as a tension gauge i think i can get plenty close enough. You need to say what pressure you use because w/o that no measurement means anything to me because the difference could be nite and day depending on that. In any case mine is now tighter and i'm watching it. But like i said before it became loose there was a lot less dust on the wheel so i have no doubt it was the looseness. It's never shredded that much and it's never been nearly that loose, and they both occurred at the same time, so i think it pretty obvious.

Afternoon Daz.That's correct.Cold,mine has approximately 2 inches total,when I push it up and down with pressure or just about to the point ya have to really push on it to get it to go any further,and approximately 1 inch when it's hot.I do not have any type of pressure measuring device to get the exact amout of pressure I was putting on the belt when I did this.And where I checked that was NOT at the belt's tightest point.It was just a random check on the top of the belt in front of the upper belt guard.When and where I set the free play is at the tightest point of the belt,COLD, measured in that slot in the lower belt guard,and with the rear wheel raised.I raise the wheel so I can rotate it to find the belt's tightest point.I appologize for not explaining myself better.Remember what I told about me not bein too bright?? lol Well,there ya go! lol

And today,I took temp readings hot and cold.When I left this am,the belt was room pr the ambient temperature,67*.When I just came back in after traveling approximately 80 miles which should have heated it up pretty good,the belt's temp was 92* which is compatible with what the other gentleman got.

Did ya happen to check your pulleys or cogs for any sign of metal burrs or jagged edges??Just wondering as we wanna cover all the bases.Dave!!!

No, but i'm sure they're ok. I will check them if tightening doesn't stop the dust tho.

Das:Almost every Friday night,a bunch of guys like myself,get together for coffee and discuss motor vehicle problems in general.So tonight,I brought up the shredding belt problem which we kicked around and everyone agreed that,even if ya only have a tiny burr on either cog,that will raise hell with the belt and leave a tell tale sign of rubber on the wheel or someplace on the back end of the machine.Now I'm not tryin to belittle or doubt you or anyone else,I'm only tryin to help and again, just wanna cover all the bases.And the loose belt theory also came up and it was also agreed that an extremely misaligned wheel could also cause that to happen.But I thought you said the alignment was ok or only slightly off.So, if that's the case,that brings us back to the burr on the cog theory.Now if ya think you have the problem solved,then I'll stop diggin and move on to somethin else.But as I said,you do have my undivided attention on this problem as what I'm lookin for is the "WHY".lol Dave!!!

Well, i have had the shedding issue before. And i should mention it's not "shRedding", it's shedding just dust like brake dust which is totally normal, just not to this degree. But yes, alignment DOES amplify the issue. But i have found a way to align it quite accurately so i'm sure it's good. I can't say whether tightening the belt will take care of it but i'm 90% sure it will, especially since it only started it's latest episode right when it went loose after i put the tire on.

Unfortunately i can't tell you if it's now shedding normally or still a lot because it doesn't just happen after a few short rides. It took a good week or 10 days to notice there was a lot more dust than normal. So i'll know in maybe a week for sure if it's good and will report back. Thanks for the concern.

Ok, i called mickey cohen figuring if anyone would know it's him. Asked about the hot/cold thing and he said thats normal. Asked about the triumph 10Lbs/.25" spec and he said he feels thats too tight and he adjusts about .75". And thats where i have it now already, andi'm keeping it there. 3/4" when cold which will probably equal triumph's spec when hot or a bit looser. I think if triumph just changed thier manual to read "when hot" they'd be spot on.
