where are they wearing.......inside or out side edge


I don't know where by the time I find out they are destroyed wrapped around the pulley and one usually take the other one out, just chunks of rubber.

how long do you expect them to last?

Still have the original on the water pump 1900 hours. I know that the vac ones have more stress but I expect a year.

Assuming they are properly aligned, the biggest factor in short life is HEAT.

Try increasing the airflow and insulating hot surfaces nearby.

sounds to me more like it is the wrong V grove and it is chewing them up because it is not sitting in the pulley properly.....

how tight are they as far as tension goes?

Pretty tight if you push down on them you might get 1/2 inch or less

The exhaust runs right next to them maybe 1 1/2 ", 2" at the most. now that you said that it is usually the closest one that goes when there is anything left.

Just some of that heat tape, hey?

Thank you,
Keith

The best solution is the hi-temp tubing.

To install the tubing you have to take off the exhaust pipe.

You can install hi-temp 2" wide wrap on the existing pipe, without removal.

Here is the 1400° wrap we have found to work best:

Larry,

Found a crack in my exhaust pipe and took it in for an estimate to replace the whole pipe. I would do it myself but looks like a major pita. (depending on the price I might still do it)

When they order the pipe i'll do one of the things you mentioned above.

Meanwhile I think I am going to try to tighten them (belts) see what happends. When I put on the new belts I slip them on like a bike chain. I was showed that by the mech. in town and I have never adjusted or moved the blower at all. Maybe they are slipping. What is the rule of thumb for how tight they should be? The mech. told me "little looser then a fiddle string." wtf does that mean?

Thanks for the info,
Keith

Try using industrial grade belts,and if those belts are near the exhaust,ya,use the exhaust wrap.

Belt tightness depends on the style of belts used.

Our TM's use 3V & 5V belts on a short span.

Midway between our sheaves, you should be able to push down about 1/2" with your thumb.

Longer spans will more down movement.

Keith, When you replace the mainfold be sure and wrap it before its installed. Its alot easier and you'll get a better job. It also be a good idea to have some sort of shield to protect the wrap when the belts come apart again. Without it when they start thrashing around it will make a mess of the wrap. Make sure those belts are tight enough. I know they say you can over tighten but them I have never found that to be a problem. All that being said, my guess is that there is too much restriction in the blower plumbing. This causes a lot of pressure against the blower and that makes the belts slip no matter how tight they are. Call me sometime and I can show yoy how I fixed the belt problem on my PowerClean unit.
