aslomp 373734 26 Lug nuts either
Lug nuts
Since about October I've replaced 11 lug nuts and studs.:-( They snap of at the nut and it is happening on all four axles on this manure tank. The other two tanks, we have never replaced one.
I can't find anything wrong,so if anyone has any ideas I would love to hear them.

Re: Lug nuts
Is do always the same driver work with this tank?

Perhaps the steering needs to be calibrated.
Or, you tighten the bolts too hard with a pneumatic wrench.

Re: Lug nuts
Possibly the nuts are either too tight or too loose. I believe they should be torqued to 450-500 ft/lbs.

Re: Lug nuts
Hmm.. I would say they are Either overtightened or the hub is defective.

Re: Lug nuts
Maybe the tanker isnt leveled when connected to the tractor, and one axle holds more weight than the other, and in turning one axle holds more load than the other.

Maybe there are oversized tyres on there, and when turning bolts snap because they are the weakest link here.

Better to snap bolts than rims...

Frank: 90% of the time I drive this tank and I have been operating these type of tanks for four years. I have checked the steering and everything is aligned and working properly.

Russ: I always tighten the lugnuts to 500 ft/pounds by hand and they never seem to run loose.

Bobo: That's true, bolts are alot cheaper than rims. I have checked and the tank seems level. The axels have hydrolic suspension so the wieght should be equal on all axels. We run 28X26 Goodyears so they are not that big.

Thanks for your time guys:-)

Re: Lug nuts
One more thing...

Do you often drive on slopes? That might be the reason for nut breaking... Because the most of the weight is on lower tires, and when tanker wiggles a bit, the nuts get much more pressure and break...

Re: Lug nuts
We have a lot of hills around here, but why wouln'd the other 2 tanks have this problem. The other tanks have over 5000 hours on them. One has even been upside down in a ditch.

Re: Lug nuts
Is this a new tank aslomp? Something you could check is too switch a tire and rim from one of your other tankers onto the problem one. If the studs break on the other tanker, then the problem is with the rim. Just a suggestion to narrow the problem down.

Re: Lug nuts
I bought this tank in May and didn't have a problem till October. I could try switching tires

Re: Lug nuts
What came to me just now...

Did any od the bolts you replaced break, or just the original ones break?

Maybe they had some issues with bolt quality and thought that they will hold...

Just an idea...


@Russ: I don't see how changing one tire and rim will help, but you need to switch all 4 of the tires to get the wanted effect. Changing just one tire, or one axle is like doing nothing...

@ aslomp: I wnat you to fix your problem soon, because this isn't a small thing to have in mind...

Re: Lug nuts
So far it has just been the original bolts. I used the tank all day today and not one snapped:-D
