5 on 150 ?? Set me Straight

[landtech]

So I have 5 x 150 what? Is that mm thus it would be? Almost 6 inches for the circle?
5 1/2" from lug 1 to lug 3, but that is not the diameter of the circle?
"......5 bolt holes arranged around a circle which is 5.5" in diameter. This may also be commonly referred to as 5 on 5.5 bolt pattern."
Hers is my research
There are a few reason I could think off why they try the 5-150 bolt pattern:
-It would accomodate bigger CV joint
-Weight reduction although very minimal
-Ergonomic request from the assembly plant So I have 5 x 150 what? Is that mm thus it would be? Almost 6 inches for the circle?
What is more, the hub studs are 10mm and not 8mm, the splined length on the drive flange is longer and the front wheelbearings are bigger than the 80

Help ?

So when ordering hubs for my trailer what do i order?
5 x 150?

 

[1loudLX]

if you want to be able to run wheel/tires that can act as spares on your 100 series yeah, 5x150. 150mm between the studs like you said, 1 n 3 or whatever.

Not too many wheels out there to choose from...i hate the bolt pattern for that...cuz im one of those guys who wants some bling bling chrome.

 

[landtech]

It aint easy

I am not sure if it is diameter of circle or hub to furthest hub?

 

[landtech]

Cool

Now i see

 

[hoser]

What is more, the hub studs are 10mm and not 8mm,

If you are talking about wheel studs, the LC100's wheel studs are 14mm x 1.5 pitch.

It ain't easy being a rookie

 

[1loudLX]

maybe not, but your question is helping me learn about my truck too. Thanks Hoser...i dont knowif ill ever need that information but its good to have.

I always assumed that the 150mm was the diameter of the circle on which the lugs are centered...

 

[100 TD]

i think this is how you measure the bolt pattern on a 5 lug, please someone correct me if im wrong.

OK

WRONG!

5 x 150 =

5 studs centred in a 150mm circle

If there were 6, 7 or 8 you still don't measure between them unless they are through the diameter of the circle

 

[1loudLX]

ok thank you...editing my posts now.

 

[hoser]

Well, hold it. I've seen the 5 lug bolt pattern measured in different ways, center to center and similiar to how 1loudLX posted (and then deleted). I prefer it center to center as e9999 and 100TD know it.

 

[1loudLX]

ill put it back up, maybe someone can set my brain straight.

ill put it back up, maybe someone can set my brain straight.

Draw a line from the centre of one stud through the centre of the axle to a space inbetween 2 other studs and imagine there was a stud there to measure to.

In other words draw a circle 150mm round, then put as many studs as you want on that circle, the diameter always stays at 150mm no matter how many studs, you must measure through the DIAMETER or CENTRE of the circle

4 x 150 = 4 studs, 150mm = a 150 mm circle that the centre of the studs are mounted to.

5 x 150 = 5 studs
6 x 150 = 6 studs etc

hope this helps

 

[e9999]

as far as I know, the nominal "distance" (150mm, 5.5" etc) is the diameter of the stud circle. If you have an odd number of studs, obviously you can't measure that from stud to stud. If the definition I mentioned is indeed correct, then I imagine that what some people do is to measure from the center of a stud to the outside edge of the almost opposing stud, as a first approximation of the true diameter. Maybe that's what some of you are referring to?

 

[1loudLX]

i think i get it now. Thanks

Bolt Circle, Stud Pattern or PCD( pitch circle diameter)
The diameter of an imaginary circle drawn through the center of each lug hole. Also referred to as the bolt pattern.
Edit: You just posted before me!

 

[hoser]

Ah, I see now how people are measuring it differently. One is approximating it and the other way (100TD mentions) is more precise and also more difficult to measure. But they are all talking about the same thing.

Not stupid, just a little off. What you were referring to was the method for approximating the bolt circle. Hoser's link shows it clearly for a five lug pattern, it's from the center to the outside of the other stud. I crudely marked up your drawing but you can see how the two circles intersect at the opposite side, right on the bolt circle.

 

[LXPearl]

Therefore, the radius from the center of the axle to the outer edge of a stud is 75 mm (half the diameter), and the 5 studs are placed equal distances from each other along that radius/circle.
