What have you done to your 5 ton this week?

[8madjack]

Had some fun changing a tire along the road.

Then once back to the shop, switched several around to get those XL's off the front axle.

which of the super singles are these? This is not the first time I've seen a post on this and now I'm concerned, are these a problem?

Michelin XLs. Some go bad. Mostly cause of age. I have had blowouts on a 95% XZL. This is my XL blowout at 60mph

That looks like it was fun

Howdy Josh,

Years ago I found a recipe for homemade Kroil and I have used it in my shop since with great results. It is especially cost-effective for jobs that require a lot of fluid.

Interesting information​

Machinist's Workshop magazine actually tested penetrates for break out torque on rusted nuts. Significant results! They arranged an test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Penetrating oil ..... Average load

None ............ ......... 516 pounds

WD-40 ............ ...... 238 pounds

PB Blaster ............ ..214 pounds

Liquid Wrench ...... 127 pounds

Kano Kroil ............ 106 pounds

ATF-Acetone mix... 53 pounds

The ATF-Acetone mix was a "home brew" mix of 50 - 50 automatic transmission fluid and acetone.

Note the "home brew" was better than any commercial product in this one particular test. A local machinist group mixed up a batch and all now use it with equally good results. Note also that "Liquid Wrench" is about as good as "Kroil" for about 20% of the price.

You will have to keep the mixture in a tightly sealed container and shake it vigorously before each use but it works!

I have also found that heating the bolt rather than the surrounding area and then letting it completely cool seems to swell the surrounding material and loosen the bite on the item to be removed.

And lastly, I use a heat gun to heat the part for very rusty parts before I apply the penetrating fluid (lots of fluid repeatedly).

Good Luck!

Tom

My $.02 for broken bolts and badly rusted bolts I weld a nut to the broken bolt and it usually backs right out after cooling. I've had great results with that.

Good to know, thanks, I've got Goodyears on mine, guess I'll stick with them.

Yes, Michelin 14.00R20 XL.

Yes, these tires are getting old but, I believe I overheated the tire that day, 95 degrees outside, around 34,000lb on rear tandem, 55mph and only 85psi in the tires.

I've had many uneventful loads on those tires running up to their max rating of 40,000lb on the rear with the max air pressure of 100psi in the them.

The only thing different was that someone pointed out to me that my wheels are only rated at 85psi, so that day I only aired up to 85psi and loaded a little lighter. Then about 20 miles down the road... boom!!!

A lot of people claim that the XL's where bad from the factory new. I'm thinking they weren't designed to handle the heat of being run at lower pressures, and I have never been able to find a load chart for them, like a lot of other tires have, telling you the max allowed load for certain pressures, lower than the max pressure.

Hey Jbulach, I find your comment interesting as someone who might be picking up a XL-equipped M927A2...granted, an auction truck that sat for who knows how long. You say that other than the 95F 85PSI BOOM you've had no trouble?

 

[big block 88]

I've seen the goodyears fail also... These tores are getting old. **** mine look brand new and around95% tread left as the truck only has 5k miles. But looking closely there is dry rot around the lugs.

That being said we build the goodyear at2 tires here in topeka. The plys in that tires tread is unreal... The side walls and shoulders look more like an earth mover tire than a radial truck tire.

I ran a 2" stump through one other while aired down, playing in the woods at Haspin.

Biggest thing I think is so many of these get run low or parked flat, due to o-ring or wheel valve leaks. Low tire= heat, will kill any tire, I just think some may handle it better?

I no longer have XL's on my steer axle, and the blowout on the intermediate axle was not too dramatic, even with 11 ton in the bed.

Real funny part, I was passing my friends house, he was out in his driveway with his back turned, the second my hand touched the horn button the tire blew. Fortunately he had some new underwear for both of us!

You won't find a 927 A2 with XLs unless someone just ran out of tires and used them

So it would have XZLs then? Wes, want me to PM you the listing so you can take a look, maybe you could tell me? 98G looked at it for me and them PM'ed me with his thoughts.

The two fronts are Michelin XZLs and the four rears are Goodyear AT2s.

This is what the XL tread looks like

Built a crew cab over the past few months, wasn't thinking about how tall my garage door was compared to the cab. Had to cut the roof off of it, so come spring ill be re mounting the roof again and putting it on my 923. Came out a lot better then I expected.

 

[71DeuceAK]

So did I maybe avoid the tire nightmare, for now anyway?

Towed a half track home yesterday with M923a2. Flat towed, in the snow. It was interesting. Could have used some chains.

What kind of snow do you all have in your part of Utah; talking inches, or FEET?!

 

[wadefreedomvehicles]

like 6 inches.
