Found an exhaust header nut ~ finger tight when I check today.
Was doing a coolant change, so have all the plastic off..... but cannot find the ft lb torque value in the service manual.
Help ! 8)

The 2010 Service Manual shows the required torque @ 13ft/lbs. I can't see any reason why it would be different between model years.

Thanks! Strange I could not find a torque value in the 2008 service manual. Can you share the page number in the 2010 so I can check me eye again ....
Funny that only 1 nut was finger tight and 2 where just loose. The other 5 were tight and no header had 2 loose nuts. Lucky me.
Doing a radiator flush on a hot day was a mistake .. I am beat ..
-
Look on 2-12 at the bottom of the page "basic torque for general fasteners".
-
I foind the "Muffler Body Mounting Bolts" torque apec listed at 25 ft/lbs. is that for the header nuts or the actual muffler body at the back of the bike? Couldnt find the actual header bolt spec. Ill check again.

The only way to go.

13 ft/lbs I believe.

Guys, have you seen the gaskets that are used in this application? They start off about 1/4 inch thick. I'm probably exaggerating, but they are thick. They get crushed down to abotu half this when installed. So, once they get hot, your left with the end of th pipe butted against the crushed gasket.
Does that torque value still apply being they are already crushed?
-
Dunno.
-
I'd say yes, that is the correct torque.
I am currently establishing torque ranges and standard assembly values for our shop here at work, and looking at an 8mm bolt, which is in essence equivalent to a 5/16 size for torque, a 5/16 grade 5 bolted connection is spec'd @ between 157 to 209 in/lb, depending on the K factor (lubed bolt vs dry steel, with plated in @ 188 in/lb.)
this equates back to 13 ft/lb or 156 in/lbs
personally I think trying to apply a specific torque on these nuts is pretty ridiculous, I suggest using the "turn of the wrench" manner on them, tighten till snug, and apply about 60 degrees more rotation.... that is all they need.
::) ::)
some people tend to do more damage trying to achieve a set torque, that is a bit erroneous....
:nuts:
kinda like the torque Kawasaki spec'd for tightening the oil filter.... :stirpot: :stirpot: :hitfan: :rotflmao: :rotflmao: :rotflmao:

Man of blues, dumb question here, but we can basically ignore what the fastener is holding??? In looking at a new gasket vs used, it appears they coudl be overly compressed and end being a thick washer. I ask because I ended up removing my header at some point. One of the pipe connections refused to re-seal without a new gasket. At that point, I replaced all four fearing a repeat.
-
I can only relate my personal experiences with re using existing header gaskets, in 40+ years of owning and working on bikes, I can't ever recall an instance where I had to replace a gasket upon reassembly. This applies to the soft, thick compressable copper, and thinner copper gaskets. I guess I was just lucky, but then I never used a torque wrench on any of those nuts either. I have not removed this header yet, but I do have a set of gaskets that came with a header I bought a while back, I would have no issue re using those again.

I need to order fugi nuts for this assembly. I added those to my sv 650 when it kept coming loose. Never again once those were in place.
