The Stovebolt Site Forums The Parking Lot Big Bolts Dayton Studs

I sripped a stud on a big bolt dayton wheel hub.(1 of the 5 there) How do you get those studs out for replacement? Mert

I don't know if your Dayton wheels have press-in or thread-in studs.
This may sound too obvious, but press-in studs will press out. You just need a suitable support to avoid distortion of the hub and a big enough press. Don't expect them to move for a love tap from a tiny tack hammer.
If they are thread-in, you might get a stud extractor/installer to do the job after a repeated soaking with penetrating oil but you might have to resort to more forceful methods. If kindness doesn't work, heat may help. One way is to get a nut that is meant for the stud (can have threads in poor condition or stripped) thread or shove it a bit less than half the depth of the nut onto the stud and weld it solidly in place filling the hole in the nut as you work out. Once it has lost the cheerful red colour but before it is fully cooled apply some more of your favorite penetrating oil at the wheel/stud joint that will at least partly go up in stinking smoke, place your socket and impact gun that you thoughtfully placed near by before welding onto the newly made hex on the stud and have at it. Many very stubborn studs and sheared bolts have come loose with this method. It works better on short studs as the heat cycle has less distance to travel to free the rust. Applying heat to the parent metal the stud is threaded into by another way should have the same effect but for a big lump of steel you will also need a big torch. Sorry if it seems I'm stating the obvious here.

Hy gto57, could you tell us what year and size of truck you're asking about, that way we can give you the facts on stud removal, rather than guessing.

Thanks. Your response is much appreciated. Mert

Hi. The truck is a 1965 c-80 chevy. Thanks. Mert

Hy gto57, according to my Canadian parts book that stud should be threaded on each end, 5/8" x 11 x 2 3/4" GM p/n 2162150, Napa p/n TWD WA1281 $1.29 each at the store I checked, hope that helps.

Thanks. Mert

I did find your PN at our local NAPA. Turns out though that my studs are 3/4 inch. Do you happen to show a listing for that on a 65 chev c-80 with daytons? Mert

At this point pull one out and compare at NAPA they are pretty comon/standard.

Early on they used 5/8" studs and later transitioned to 3/4" dayton studs.

Thanks much. Mert

Hy gto57, the GM p/n for a 3/4" stud with almost the same dimensions as the 5/8 stud I already gave you the p/n for is 2066639, I can't get the Napa site to come up this morning, but maybe the guys at Napa can cross that number for you, hope that helps.

Hy gto57, I finally got the Napa site to wake up, their number for stud p/n 2066639 is TWD WA1282, hope that helps.
