With regard to the two studs on which the bar mounts can anybody tell me if it is a left or right hand thread on the stud that screws into the body (not the end that receives the nuts.). They are awfully tight and I don't want to be forcing things in the wrong direction. (tensioner is bent and wear plate worn)Thanks.
 
If they were left hand you would unscrew them when you tightened the blade.

Shouldn't matter on any sort of proper saw, where they're flanges captive behind metal. OTOH, let's hope you're not dealing with a stihl 250, with bar studs threaded into PLASTIC. Whose idea was that?
Any such piece pressed or threaded into metal deserves a drop of Loctite. Plastic, fuggeddaboudit.
 
To clarify the confusion above, if they're threaded at all then it will be a right-hand thread, but on some models the stud is a bolt with a head on the inside of the oil tank. We'd need to know what saw you have before we could answer your question with any specificity.
