I have a stud kit available now for any year 13B. The studs are made from aircraft quality forged steel. The threads are hot rolled, not cut. Then tensil strength is 195000 psi, and they are beyond a grade 8. I am not sure what they will be torqued to, as I don't have a set in yet, but 80-90 ft lbs is my guess. No maching is required, price is $320+ shipping.

Are these just engine studs?

Interested in studs.

We are talking about the studs "keeping the engine togheter ", right ?,send me an pm . interested.

No answer?

Have you determined a proper torque value for these?



If not I propose the following solution:



1. Obtain some Pressure Sensitve Tape (used to verify torque values)

2. Torque together a stock keg and disassemble to measure the values

3. NOW, install the suds and experiment with different torque vlaues to obtain the same pressure tape reading as a stock tension bolt setup.

They aren't finished yet, the company making them is going to test them to determine the correct amount of torque.



Comitatus, yes these are engine studs. Instead of the Stock Tension bolts, its a stud kit.



Studs provide better clamping because instead of twisting bolts, you actually stretch the studs at each end. Not to mention engine fasteners should be replaced after each use.

Mint!



This is for the entire engine round correct, and the front iron is threaded, right?



So I take it you thread the studs in by hand and then use nuts on the opposite end? Or am I completely off base here..







Excuse me I don't do teardowns as often as you to say for sure how you would assemble this kit.. Forgive any misunderstanding on my part...





Let me know though!

lets see some pics homeboy.

I would imagine the torque bieng alot less then on a bolt.

Which is why Pressure Tape testing should be utilized to duplicate the correct torque values

Correct.

Okay so how can you be sure each stud is threaded into the iron all the way before you torque the outer nut?



It might sound silly considering there isn't alot to get in the way of the threads being dirty or something..





But can you assure there is a very minor chance anyone can make the mistake of partially threading into the iron and torquing the outer nut? You won't have the full thread strength although your torque wrench will click to spec, that can be disasterous..





I might be off base again but these are things I've run into problems with aside from engine building, other applications in life.. I'd want to be 100% on it when putting an engine together.





If it were me I would snug each stud into place by double lock-nut on the tip of the opposite end, then undo the lock nut and torque the proper nut to spec





Are people going to be aware of this type of procedure for assuring proper full threading or is it a no-brainer type of install?

FYI I'm pretty interested in picking this up should you be able to attain sufficient torque specs..

You should use a bottom end tap to clean the threads with this kit, and use it to cut several more MM of thread in the front iron. After cleaning the threads you should run the studs in by hand, and you shouldn't have any problems with not having the stud in far enough.

I have 7 kits in stock currently available. I am currently assembling 2 motors of my own for testing, and possibly 2 motors for customers over the next month or two. Torque specs are 120 ft lbs. If anyone is interested PM me, and I'll give you the shop phone #.

I just got the rest of the hareware in and I should have a motor done with them next week. I believe I am going to goto 85 ft #s, and start with that. I know it can goto 120 ft #s safely.

I thought the idea was not to overtorque...



So these aren't to be torqued to 120, they can just handle 120?



What's the OEM torque value offhand anyways?

OEM is 23-29 I believe? Something close to that.



I am assembling them to 80 ft #s.

I just did a test on a motor since people are so worried, and

the rotor housings did not crush at all, even down to the .001" ...



$350 shipped is the price tag.
