Head Torquing

Well, they do flex side to side pretty easily, that's kinda normal. It is a very long stud.

That sounds more positive Twins. Well give the double nut a try tomorrow just to see. It’s really in no danger of letting go from what I see. Could well be flex. I’ll know better tomorrow or at best, when I take off #2 nut.

Thanks guys. Appreciated as always.
 
Oh yeah if it's just moving around in the hole that's completely normal. :thumbsup: The holes are loose by design several act as oil return passages. I took that it was TURNING loose.
 
If you're concerned with it possibly being backed out, measure how much stud is sticking out above the head and compare that to the others.

So ya, all eight studs were identical in mobility and length above the cap so I left them alone and refastened the acorn nuts to 30 Ft Lbs. Note the swapped out washers on 5,6,7 &8 as advised. Did have a real problem getting the torque wrench on 9,10 & 11 even with a 1/4 inch wobble joint but fastened firmly by hand. They likely make a mini torque wrench but I don't have one.

Thanks again to all for the advice/knowledge. Tanks going back on this afternoon to see what I got.

Good job!
I got a 3/8 x6 wobble extension with a 3/8 17mm 6 point socket, and can now easily torque those inner 4 :thumbsup:
don't forget to hand snug the 6mm over the cam chain tensioner. Usually involves a chain of 1/4 drive sockets, wobble extensions to get on the head
 
You need to take the chrome covers off the points and advance housings for better access to #9 and #10, those two bolts under the spark plugs. You still need the wobble extension, but they're much easier to get at with the chrome covers removed.
 
Ya, saw that and removed them but still difficult to get my torque wrench operating, even with 1/4 inch wobble connector. All the rest are good, think I’m ok with the hand firm.
 
Well just had a crazy idea for torqueing hard to access nuts.

Can you access them with a double box end wrench? Do you have a fish scale?

Just measured my Craftsman 17mmX19mm box end wrench and center to center it is 9 inches. That's just .75 of a foot. So if I was to put the 17mm end on a fastener and hook a fish scale to the 19mm end and keep the fish scale pulling at a 90º angle to the wrench and pulled on the wrench with scale reading 40 lb. that would give me a 30 foot pound torque on the nut.

With a little imagination one could use this as a test of the accuracy of a torque wrench!

Math is fun... :smoke:

Impeccably timing, thank you all for great information. I’m going to be doing this procedure as soon as my new washers show up. This forum is invaluable to the xs650 owner.
