the concentrics are not a tensioner per se......better
they keep the belts tight lik they should be.....PLUS you can change the belts in about three minutes.....
Gene...ever try a Gates green belt....they're the best

I'm not a manufacturer...

THIS is the proper way to tighten yor belts...
a BRACKET with two concentrics.....
i've got templates for most 45's and 47's
i believe this is Chris' machine

That is Awesome!
Yes this is my machine and lemme tell ya


It is sweet to be able to tighten the belts. I run the covers for posterity, still takes me about 2 min to tighten either or both belts, routine maint thats a habit now.


Thanks for Everything Bawb!
Friggin Luv U Dude : )

Yea he had it all re-done at the local distributor. Re mounted on a plate with slide holes for adjustment. But I thought they had said it wasn't necessary they had a solution. ???

I find it strange that Larry has not chimed in? If he had a question on a spot removal Larry would have been the first to respond with a link to his site and one of his products.

Larry has a tendency to interject his wisdom into all posts except those about problems with his equipment or products.
He probably just hopes those posts will bury themselves. Nothing new.
I have experienced the same thing with pm's and phone calls. If he can sell something you will get a response.
If it is a problem...good luck.

I brought up the same issue 15 posts ago. I'm sure Larry is aware of this thread. If he was going to offer any suggestions he would have by now.

I find it funny that Larry introduced his NEW tensioner design........ in another completely unrelated thread. :winky:

Perhaps he will send Lyon a retrofit kit at no charge? That would be cool.

It is funny how there is a problem with a ten year old machine and there is a poking at the manufacturer , and y'all want him to repond to an attack.

Larry is smart and will not respond to an attack. So he post in another thread, where he is not under direct attack.

I am not surprised that no one thinks the "Cobb job" is awesome for being a ten year old unit that ( might eat some belt quick) but keeps on making money.

TEN YEARS AND HE'S ONLY HAD TO CHANGE SPARK PLUGS AND SOME BELTS??????

HOW MANY DIFFERENT MANUFACTURERS UNITS ARE OUT FOR TEN YEARS WITH SO LITTLE PROBLEMS?

Just sayin

Michael,

I re-read the posts, and most seem to be genuinely helpful hints for various possible fixes. I wasn't until post 28 that I said anything about Larry, and then it was only a suggestion that he chime in. It's in any manufacturer's best interest to take an interest in their customers and their issues.

Several things to consider:,

1. user error... (No offence Lyon)

Are the proper belts being used? IE. Are the Sheaves designed for the 4x stronger 5vx series, and B style belts are mistakenly being used?

2. Are cheaper belts being used? And I dont mean $$ wise, I mean the quality... if you are using the same brand as always, maybe their quallity has gone out the window (Like what has happend to me many times)

Try matching the belts to the Gates Green "Powerrated" belts (Thanks BAWB), or the "Predator" series, I have had tremendous success with both, in situations were I was burning through belts every month.

His delayed response is understandable.

I'm sure it took a few days to fabricate a tensioner, and then take pictures to show here.

Lockhart is blaming us but it doesn't bother Larry to bash other distributors or manufacturers he doesn't represent. Yet when it comes to his products he has thin skin. ???

I don't think he took any bashing for days until it was obvious he wasn't responding.

That was just odd. He could have said I don't want to get attacked so I'll post it in another thread but he just never said a thing.

That's a strange way to handle it especially for a distributor/manufacturer, but I guess we all have our peccadilloes.

I'm looking into getting mine surgically removed. :winky:

I use matching cog belts from an engineering shop that's been around for 100 years, I tried automotive and the green ones don't work, the cog belts are the correct belt, I'll check out Cobbs new set up

The slotted plate is simple and cheap, and is a very common way to tension belts. Every belt-driven machine in our shop uses a slotted plate to adjust belt tension.

A spring-loaded tensioner is a good thing though, if you're willing to spend a little money and have the room, since you can change belts more easily.


If you find it terribly difficult to change belts you might want to try a link belt. If they stretch, take out a link.
