R1200RT Valve Cover Torque

[Jeffrey]

What is the correct torque specification for the four valve cover bolts?

 

Thanks for your help.

Jeffrey,

 

Not being a hex head owner, I haven't any specific data yet feel compelled to issue the following warning, namely, VALVE COVER FEMALE THREAD STRIP EASILY (hmm, that sounds salacious). Oilheads have 7 newton meters (that's something like 4.5 foot pounds) as torque value.

7 nm is correct for the hexheads also.

Just "snug" - with a short wrench. These bolts are shoulder bolts - with a shoulder that bottoms out when they are deep enough. They compress a rubber donut that actually presses the valve covers into the rubber gasket that seals them.

 

Tightening them more than snug doesn't make it any more leakproof. And it is way easy to strip out the threads in the head.

 

As you turn them - one finger on an allen wrench end - once you feel them get to the shoulder - a tiny "snerk" on the allen wrench is all they need. This is a case where anything but a very expensive torque wrench will have you ripping the threads out. A cheap clicker wrench is almost certain death to those threads.

Ah, so 1.0 Snerk = 10.0Nm. Now I understand!
