IIRC, the head bolts are 'torque to yield'. Tighten in sequence to spec, then 1/4 turn????

 

That depends on whether you use OEM or aftermarket gaskets.

Aftermarket gaskets are torqued in steps up to 42 ft lbs and OEM gaskets are torqued to 7 ft lbs then turned a 1/4 turn.

 

Update.


A pulled stud is the problem, none of them on that cyl seem to have thread inserts, certainly not the one that pulled.
So any more advice?
Can an insert be installed with engine in place, (I hope)?
Is a new stud required?
Any info is helpful.


I've already removed head and cyl.


Thanks

 

While I have not had to deal with this problem (knock on wood), most people have repaired this without pulling the motor further apart. Timesert or Helicoil it and go. Some of the usual tricks like using a vacuum, lots of grease when you do it would help keep the crud out of the bottom end. Your original stud should also be OK to reuse.

 

Yes it can be repaired but you might have to pull the case and bring it to reputable machine shop familiar with Harley case repairs..

 

Sorry to hear about this John. Good luck.

 

Thanks Chaz, it'll allow time for those other parts to come in.
