valve cover damage

[ME 109]

OK, so here is another question. Is it possible to calibrate a torque wrench?

Companies do it for you. I don't know how one could do it oneself. Call up Snap-On or Mac, and, if they don't do it, they will know who does.

Who calibrates the calibrating machines?

Cylinder studs.........
My bowel nearly falls out every time I get up near max torque of each stud. Then it springs back when the torque wrench clicks.
Just thought I'd pass.... that on.

Well, I was going to make a cute response, but I have to pass this on instead:

When I read your post, it looks like this:

So, what's up with that???????

Edit: Now I see the whole thing. Must have been while you were editing your post.

P.S. Please let me never help you work on your bike and witness your bowel falling out...

I use my 3 torque wrenches checked against each other, beam, clicker and digital, all right on the money. I either have 3 wrenches that are all equally out of whack, or they're good to go. I torque to only 23 ft/lbs, oiled fasteners and all...

Sorry about that Major, not quick enough to edit/add to my post.

BTW, It's OK. I always wear pants when working on my bike.
Shorts do have their short comings though.

Twist,
This happened to my R90S. The studs did not pull at all. BUT the upper rear corner of the cylinder base was "bent" from compression enough to cause an oil leak when I fired it up with a new head, studs rockers, etc. I had .5mm milled from the base and used (2) .5mm shims (stock is (1) shim) under the left cylinder. The point is, it took a mighty whack on the cylinder and didn't pull the studs at all.

Yeah, that road grit really gets in everywhere...

...but maybe the hole in my valve cover was a little larger than yours?

Gee Rob, nuthin" a bit of rub'n buff couldn't have sorted!
This was the result of a 720 degree spin on the right cover. The cover came off, the bits were flushed clean and it was ridden home after the holes were taped up! It's still going strong, and the oil and filter change showed nothing untoward luckily.

I see your nicked valve covers and raise you some pulled studs :

Now THAT'S what I mean by the cylinder taking a hit.

I see the crash bars were removed so as to hide evidence.......
