combat wheel info

Hi all, i'm working on an F60L cab 13 and i need to replace a few of the studs and nuts that hold the two halves of the wheels together.I was wondering if anyone had specs,or a source for a suitable replacement/part number or what have you.
A friend of mine says they look like 7/8" British Fine thread, is this true?
I'm going to need ten of each.

I really want to get this one rolling...

thanks

My measurements say your friend is correct, that the thread is a 7/8 fine Whitworth. Unfortunately, I haven't found a modern source for the studs or nuts. The nuts are sometimes available from people who are scrapping a rim that would be unsafe for use. If I were scrapping a rim, I would also recover the studs since I don't know another source for them (but it would be an effort to remove and clean up the studs). Even cleaning the threads isn't as easy as you might think because the taps and dies seem to have pretty much disappeared too.
Have you tried contacting LWD Parts?

I know this is not 100% original , but why could a more modern fine metric thread or a SAE thread be used as a stuff ?, the average guy would never know as well there may be a modern source to get new ones for a newer truck ?

sure would be easier dont you think ?

Does anyone have a pic and measurnments of a NOS one to see exactly what the measurments are ?, I bet if you do enough searching a person could find a replacment and save alot of hard work ??.......... maybe

I've considered turning the appropriate studs from modern bolts (SAE so that the same set of wrenches fit everything on the vehicle) or using modern studs, if suitable exist, for the 20 inch wheels. You've probably seen and measured enough to know the studs are different on the 16 and 20 inch wheels. (not the threads, just the heads, different welding to the whhel half as well)
If you go to modern threads, consider doing enough so that the whole vehicle, or your whole collection, are the same so you don't have to remember which nut fits which wheel.

A quick web search reveals many suppliers of BSF wheel studs. Here is just a couple of examples.
They also tell me that Scania trucks use this thread form.

Is BSF the same as Whitworth Fine 7/8-14? (don't the Whitworth threads have a 55 degree form instead of the more normal 60 degree?)
The shortest knurl length I saw on the Alko page for 7/8 BSF is 17 mm, much longer than the thickness of the two parts of a CMP rim. But the web sites do make a starting point. At least the wheel half joining threads are all right handed.
See Tony Smith's note on the thread below - I was working from (presumed faulty) memory when I wrote the above.

Corey Myronuk · #7 22-01-10, 04:01

ok i have a source for the bolts that hold the wheel halves together

,7/8"BSF,9 threads per inch, in 1 3/4" and 2" overall length.grade 8. PM with your needs.
still working on the nuts...

will let you know what i turn up.

cheers

Bob Carriere · #8 22-01-10, 04:26

....are you sure of the thread count........ 7/8 BSF should be 11 t.p.i.

Keep looking for the bolts the TPI will ot matter if we can find matching nut to the bolts.

Strange discovery at the barn.... Grant has some 20 inch rims that have the tappered/recessed bolts similar to what you would find on a 16 rim..... usually the 20 inch rims have a flat mushroom head bolts welded on the insed back rim.

Has any one seen that before...??

Corey Myronuk · #9 23-01-10, 05:49

i'm not up on the bsF thread count but what i have here sure looks like 9 per inch unless im counting it wrong...

Thats what they have waiting for me...i'll take a couple of nuts with me when i go to check them out.

I managed to straighten out the windshield and get the roof back on today.
sorry for the lo res pics.Seeing the windshield laid back like that really bugged me.They bent the roof to fit their crazy plan too.

Bob Carriere · #12 03-02-10, 22:46

.... that certain employees of the Big three were making some on the factory CNC.....apparently in there spare time..... the big job is writing the program.... then you just feed the machine with free raw stock......

I got 8 of them..... and they are not cheap....and they are almost too beautiful to install on a CMP..... and have asked for 100s more on behalf of all of you.... If they become available I will let you know..... or if you see GM going broke you will know why.....

I am thinking of welding mine on so they can't be stolen....hihihi

Bottom line ....yes they can be made......

You can torture me .... but I can't say anymore....

So! I had better send this to Presedent O!! NOW we know the truth!

lendlease · #14 05-02-10, 10:29

I think the Champion brand is JAPANESE. Many CMP (blitz) nuts and studs were made in Japan to supply the local market after supples of war surplus had dried up. Also, the DKK brand is JAPANESE. Does this qualify for NOS???

Max Hedges · #15 03-02-10, 22:47

The Bolt with the round head is 2inch long

The other is 2 3/16 inch long

Each wheel has 2 starter threads that are slightly longer than the other six (in both styles, Countersunk head and Mushroom). The long studs are 2 3/16" and the short are 1 7/8".
