Help finding new Head stud (problem solved)

[Nal0x0ne]

Bought a brand new torque wrench to make sure I fastened all my head nuts and bolts to spec... well either my wrench or the head stud must have been faulty because it snapped the head stud right in half. Now I am having a terrible time finding a replacement. Does anyone know the part number, or where I could find them?

Might want to check eBay. I believe that the VT500FT Ascot engine & the VT500 Shadow engine use the same head bolts. Sneak up on those final torque figures by about 5# to 10# increments.

Good luck

I think I have found it, or at least I am sure enough to spend $15 on it to find out. It was listed as a part of the crank case components, #10 on the diagram here. Its the smallest of the engine studs and it runs right behind the cam chain so I'm thinking this is it.

So in the end every company I contacted said they had the part, then after taking my money told me they didn't. 3 refunds later I am sure this part is now completely obsolete. I will have to find a suitable replacement. Does anyone have any suggestions?

U can always try making your own if you have a metric tap and die set. just use a good grade peace of rod when you thread it , a machine shop will make you one if you have one for them to look at and measure but will charge you big time

This stud is the same but 200mm long, the only difference is the threaded length will be longer on this stud even after it is cut down to size.
My biggest concern is strength, this is far from my area of expertise, it was a big leap for me to take the engine apart in the first place and its not going so well!

the tensile strength of the stud is 125,000 PSI. does that seem reasonable?
anything else I should consider when replacing this part?

Here's a long shot: http://www.arp-bolts.com

Perhaps if you contact their technical department with the dimensions of your original head stud, they might be able to source one, or at least provide some tensile strength data.

Good luck

Have you tried David Silver Spares in the UK?  They have lots of discontinued parts.  The Ascot wasn't sold in Europe but a very similar model - with the same engine as the Vt500 - was sold there.  I think maybe it was a VT500E??

So I ended up going with the generic stud I found on amazon and it worked perfectly. Now if I can only solve my carburetor troubles
