Stihl BR800X fan nut torque value ???

[ZeroJunk]

Can somebody with access to the Stihl specifications advise me what the torque value should be for this ???

They did away with the threaded hub and went to a taper like a chuck. I have one that the fan slipped one time, or hub broke. Not sure. But, the replacement literally wore the taper off the crank shaft. So, I am having to replace the motor and the fan. May lap the mating surfaces a little.
Anyhow, I really don't want to poke a hole in the top of a piston.

30Nm. The tightening area on the cranckshaft has to be completly clean and oil free.

Thanks brother. That is a little over 22 foot pounds which is the unit of measurement of the type torque wrenches I have. We'll catch up eventually. Maybe.
