250-500cc Secret tool for Cylinder Nut inside the power valve cover?

You fluppin tell em big timmy!
I bought into the itallian husqvarna so im techincally an infidel!?!

too informative

Good post Timmy!

Cheers for that Timmy!!

Folks, please read the Service Manual before attempting any serious maintenance work on "anything" really. Not torquing the cylinder bolts evenly might be a good way to crack a cylinder. Some equipment manufacturers specifically instruct to torque certain bolts without any lubrication, at other times to use lube. It can alter the applied torque dramatically, so good idea to follow the instructions, if given. If not specified, I would assume dry torque, less likelihood of over torqueing the fastener.





Power on regardless

I'm a big fan of 3 in 1 oil, anti seize, marine grease on any bolts and nuts that don't need loctite or dry torquing...just as l like to copper spray just about every gasket.

Cylinder gaskets both sides OMG? Shits me to tears tryin to get gasket material off the case halves during a top end. Absołute worst part!

Yep, l find it easier to remove the gasket after copper spraying it, use a razor blade in between the gasket and the surface and it will pry off with no drama's ....l had to make my own base gasket in the latest rebuild after the OE gasket decided to imprint itself, on the 360 l've reused the base gasket in 2 top end rebuild with no issues.I don't use the tube version (too messy), just lightly coat, wait about 10mins to touch dry and then install, too easy.
In the past, aviation form-a-gasket was my sealant of choice on engine rebuilds especially headbolts and threads but you've got to be careful as it can distort torque figures if too much is applied and can block galleries is you spread it like it's peanut butter.
2T dirt bike motor's are piss easy compared to V8 rebuilds...l haven't tried my 4T yet

Am I the only one that just removes the PV cover/arm, then uses a socket/torque wrench?

Maybe they don't fit the bigger bikes like they do the 125...

No i use a socket, dont tell timmy i only own a 1/2" torque wrench.
But i was once told by a rolls royce engineer "a good man knows when its tight enough"
Course we wernt talking about fasteners then but i figured thats what he ment.
