Topic: Stuck tappet cover

[mashfu]

Those seem perfect to properly maintain the covers but for stubborn, abused, glued down ones, death by chisel is kind of  stress relieving  .

Yes the intent of the wrench was not to remove stuck ones, it was to not overtighten them on assembly and always be able to easily remove them.
 Plese dont try tobreove stubborn ones with it, it wont take it.

I won't do it again, but I got a set of really stuck ones off easy by gently tapping it with a mallet to knock them lose.  Didn't seem too fragile to me, but I'll do as you say

For stripped ones on a running bike, you can use a pick and slowly chip away at the tappet cover on the outer side of the o-ring (so bits don't fall in the engine). As soon as the seal is broken they come right off. And as someone already mentioned they're cheap and readily available -- I always have one or two lying around just in case.

I always use a 6pt 17mm wrench on mine. One hand holds the wrench on the hex and the other pushes down on the wrench. If your careful you can use a shallow socket. Don't use extensions, deep sockets, or anything 12 pt.

Fred has good advice.  Again, get a wrench such as the Craftsman or Snap On that has the geometry that puts the force on the sides of the hex, not the corners.

I sheared the top off of a tappet cover last week. When I looked up the torque spec for installing the new one, i was surprised: 07.2~10.1 ft lbs.

That's little more than hand-tight.

Hmmm...I disagree? Your wrench removes them without a nick, tapping with a (significant) hammer on the wrench. One side of your wrench fits them snugly and not sharply, and leaves no marks on them in the process. I like it!
