Regarding a 740 series;
I understand the Volvo wheel stud knurl is an odd-ball and I might be SOL but..

Has anyone identified a longer wheel stud that will work on the 740 hub from another manufacture that might be found at a local parts store?



Im going to run a 20mm spacer. The local availability is a sticking point because I was hoping to hit the road tomorrow. I've did some digging through the forums and found a few threads but i didnt see anything conclusive, though I might be using the wrong keywords.

I had to do the wheel stud project for an old rambler I put discs on and I remember finding a mfg'r chart comparing sizes, but for the life of me I cant dig that up again
 
I wouldn't care about changing lug nuts & running some goofy standard american size; primary concern is getting back on the road ASAP.
 
The 7/9 series utilizes 12x1.25mm thread pitch for the studs, which is a common stud. You can find these studs on many Subarus and other imports. If you can measure your current stud length, add 20mm to that and you will have a stud suitable to run. Autozone/O'Reilly's/Napa/CARQUEST should all be able to hook you up, probably gonna be $2/stud.
 
240's have unusual shanks, larger than the threaded portion (heh, I found this out during my brake swap when I broke a 960 rotor), that might be what you are thinking about? The 700 series doesn't have this feature.
 
Forgive the live posting but it's a lot more fun than working

Youll be happy to know that any and all turbobricks research on the topic always comes back to this link. Unfortunately, in the rush i was in, I had sparco spacers over-nighted and now im scrambling on the stud situation.

In the long term, i am going to get a set of kaplhenke's for the rear...Im thinking the vibe/matrix option is do-able in the meantime.

Thoughts??

edit;
55mm under head length
-20mm spacer
-XXmm bolt circle depth??
OH GOD

I was never good at math and it shows

Thats incorrect,

Its 12x1.5mm

Following up on this;

-vibe/matrix studs are far too short for 20mm spacers
-buy kaplhenke's studs (& spacers) because a) they work b) hes a great dude who came through in a pinch

I got the 240 set. Pulled the hubs and axles and used my HF 20 ton press. Simple and worked perfectly. You can spend a ton of time to get the same solution, or just buy Ben's stuff and be done next week.

Truth
For all the future-youse; kaplhenke is the way to go.
