I have a manual.. I cannot find the torque specs for the 4 rocker arm bolts. Can someone help me while I keep looking. Thanks!

 

Found it 18-22 ft-lbs..

 

I know this is an old thread, but anyone have conflicting specs? I ask because I was just performing this at 20 ft lbs and snapped one of the bolts. Real nice way to ruin your day, and future days to come.

 

You are working on an M8, right?

Make sure there is no oil in the bolt hole before you thread the bolt in.

 

nah, 15 Ultra.

Bolts are all the same length.

I did get the broken piece out though. So I do have that going for me. Hoping that HD in town has a bolt on the shelf.

No oil either. Brand new Heads... Does this apply to blue thread lock?

 

Maybe your torque wrench is off or the last guy who tightened it was a gorilla? If they are new heads you might want to make sure the bolt isn't bottoming from a shallow hole.

 

All great things to consider. I'll check out the shallow hole when I get back to it. As for the Wrench? I'll probably just buy a new one of high quality.

 

One last thought - if you were using a torque adapter (dog bone), they have to be used a certain way or the torque will be off. On the shallow hole possibility, I would think that a healthy bolt could have handled 18 lb/ft though.

 

And if it's a click stop torque wrench, some have a very faint feel when set at such low weight. An inch pound torque wrench may serve you better.

 

No Dog Bone.

I was using a large wrench, which tell sme QC may have called it. I have an Inch pound but it only goes to 200 in. I believe 22 Foot pounds would be 240 inch pounds. Not sure how much difference 40 in pounds can actually make?
