4944HST wheel with the bolts

Doc_Bob · Dec 10, 2006

Here is a Montana 4944HST wheel with the bolts. Notice that two of the bolts have nuts on them, the rest are just bolts that go into the wheel. So why do they have this pattern? Is it part of the assembly process? Is it better engineering?

I would have to search to find the exact mechanical reasoning, and data to prove why bolts holding wheels are stronger. The germans did this for the Porsche, and Volkswagen autos. I am friends with several technicians who work at the Audi/Volkswagen dealer near me and the said that in their factory tech training classes, it is stated still by the factory trainers that bolts have more holding power than just studs. I believe that the two studs are helpful, but not necessary for getting the wheel up and onto it's "perch". Two is plenty, and the other four are bolts. My New Holland TC48DA has all 6 bolts on the front axle. Seems abit of a reach to believe bolts over studs are stronger, but I've seen it, and heard of it from two sources now. Would be an interesting web search. You would think they are just being cheap by using bolts.

Not really. The machine is so nice in every way.

Having two studs really helps when installing the wheel on the tractor. Not a big deal on a front tire but when working with a rear wheel, it's easy to get one hole over a stud,start that nut,and swing the wheel in place to get the other stud in the wheel.

I have no proof that this is the reason they do it this way,but I'm sure it is at least part of the reason.

I like the explanation.

As I understood that is the reason. At least this is what I was told.

I though that's what I stated. The NH has a hub rim which helps, but not as good as a stud to hang the wheel on.

Yep, exactly the same idea. The NH is still going to be easier than lining up a wheel on an axle with 6 or 8 studs.

I would have to guess that strength has nothing to do with it at all. Most high performance engines use studs in place of bolts for the heads and main bearing caps so I think that puts a pretty big dent in the bolts are stronger theory.
