Topic: APE studs too short, what am I missing? CB750K

[madmtnmotors]

For your reference mate, the stock stud lengths are
Long Stud - 195mm OAL
Short stud - 170mm OAL

Installed height
Long Stud - 170mm
Short Stud - 130mm

Below are stock studs on APE HD studs for comparison



Below are installed (stock studs) - 170mm and 130mm height from top of case.



The best thing to do now is to Loctite the studs into the case and set the heights (above) as evenly as you can.
It doesn't have to be a micro measurement, just get them as close as you can by eye with a steel ruler.
The warning here is, don't flood the stud threads with Loctite.
Lightly coat the threads in the case with a toothpick and then screw the studs into the case.

Reasons being that too much liquid runs the risk of "hydraulicing" the stud in the threaded hole and secondly and most importantly, there's every chance that the oil galleries that let oil feed the top end will be blocked solid.
If that happens, you'll be pissed off big time. 

Can you post the overall length of the studs you're using?

If you use Loctite be careful not to block the oil passage holes on the 2 studs that have them. I learned this the hardway. Check out my leak free oil thread for a bit of info on this and installing the studs.

 I'm not a fan of torquing a stud into it's hole. I was taught not to do that on my Chevrolet race engines.  I know, apples and oranges.

I agree. Would you consider 8ftlbs "torquing a stud into its hole"? To me its just a number to keep them all even. Not actually very tight.

Just curious what you think.
