7/16 to 1/2"
Question, currently upgrading the front brakes to disk on my 70 1/2 ton. The new disk in front use 1/2" lug bolts while the back is still the original. I was thinking about drilling out the back hub and changing out the lugs bolts from 7/16" to 1/2". Am I nuts can anyone think of a reason why I cant or shouldn't.
Give me some feedback I would appreciate it. Thanks, |
Re: 7/16 to 1/2"
If you drill the out by hand the Bolts will be loose and not a press fit.

Re: 7/16 to 1/2"
Did you go 5 bolt rotors ?
Yes the proper way to install is to press them in Problem on installing a press fit lug drawing them in using a lugnut pulling them through puts far more stress on the stud possiblely stretching and weakening the stud You also have to figure out the correct size of a hole for the stud too small won't work or a smidgen to large you can have the studs turn in the hole while you try to tighten up your wheels Might be best take to a machinist or phone up an axle company like moser |

Why bother with it ?
You're wasting time and effort by doing something to gain no real improvement or benefit. Just carry two lug sockets in your tool kit or a 4 way lug wrench that fits both. Let sleeping dogs lie. If it goes well, you're out time and money for studs and machining and likely axle seals and certainly gear oil. If it goes poorly you'll get to do all that plus buy a pair of new axles for your trouble. |

Did you phone up Moser and ask them about what he size to drill and what 1/2 studs to buy ?

Re: 7/16 to 1/2"
I agree with post 5, but...if you want everything the same, I'd just call Moser andhave them make you 2 new axles with 1/2" studs, have the studs installed, also. THey did have a deal on "C" clip axles, $260.00/pair. Other folks might be cheaper, but I've known of several folks that have bought the Moser axles, with NO problems.
IF, IF you want to modify your stock axles, it can be done, but a using a machinist would be the best. The stud holes in the axles has to be precise so that the shank of the wheel stud fits with a tight interference fit, AND NOT too tight...just drilling holes may not be a good thing. You can buy studs with different sizes (and length) of shanks. THere may be a specific drill bit size to be used with a specific stud, I'm not sure. It needs to be done correctly, though! THis is not a job that can be done easily by a lot of folks. I know how to do all these things, BUT I'd buy new axles... |

This is off the Summit website.
https://help.summitracing.com/app/an...wheel-studs%3F Drill Size for Press-In Wheel Studs To determine what drill size you need, you will need to know: The axle hub material, and The wheel stud knurl diameter. If your axle hub material is cast iron or steel, your drill size will be 0.005 in. smaller than the knurl diameter. If your axle hub material is aluminum, your drill size will be 0.007 in. smaller than the knurl diameter. **When installing knurled studs, use liberal amounts of a quality Assembly Lube on the threads of the stud, nut, and washer (if applicable). This will prevent damage to the threads.** |
