The tires have rubbed the the underside of my Super Chief I'm afraid it may wear a hole in the lower tub. it's seems worse above the two middle tires. Can any one tell me what causes this and how to prevent any more wear. currently the original floatation tires are on the machine however I am in the process of converting to a new school rim & tire set up.

Boyle,

Move to a more sturdy tire. The old floatation tires flex too much under speed.

Thanks Pete,

I was think that might be the case too, kind of
similar to a drag car

I've seen that type of wear on Attex machines that have bad bearings/flanges that will let this happen. Check for bent axles too.

If I understand the question, I think your machine has had the body mishaped. I am assuming the body is plastic and the tread area is rubbing on the fender part of the body (that part that sticks out over the tires rather than rubbing on the vertical part of the body above the axles.

What I think has happened is a previous owner has tied the machine to a trailer with rope or strap going over the top of the machine and left it. A heavy load could also do this. When the sun beats down on the plastic, it gets hot and if restrained will change its shape in short order. If I am right, you will have to block the machine up at the point it has sagged the most allowing all the machine's weight to be held by about six/eight inches on each side. Use a heat gun to heat the area that has taken on a new shape - go a couple of feet past where you think you should stop. You should also put blocks under the machine so it will only drop so far. Let the plastic cool with all block in place. It often takes two or three tries to get it right. The plastic does have a memory and it will spring back (go a little farther than you think is right and it might stay where you realy want it. Be careful when putting heat on the plastic - you don't want to put any big holes in it.

This works for max bodies - but if your attex does not have a plastic body, please disregard this advice.

6x6 Friends:

Many cases of late model ATTEX's having holes rubbed in the upper body come after the original tires are OVER INFLATED. Once they have too much air they never seem to return to the correct size.

NEVER inflate the tires to more than 65" around.

If you just install hard tires you will bend axles or bust the body.

The ATTEX was designed to have soft tires, so never use any tire harder than a CHEVRON

Thanks
