Stihl MS391 Cover Screws

[deminin]

Yes it is. Those idiots are on more then one forum also. I'm sorry I couldn't be of more help, but when I posted some pictures of my saw, fish just started to get on my last nerve and pulled them. There is a moderator on here that is one of them, starts a thread that he knows will get people going and sits back and lets the abuse happen. Again I hope you get your saw the way you like it.

Yup, I got my saw under control and new parts should arrive any day. For now, I just put a couple of 6MM bolts in the empty holes, and that could probably hold forever. I've got a neighbor who is clearing a big plot to put in a huge workshop, so he is giving me all the wood for helping. I will probably have 15 to 18 cords of good oak by the time we're done. Needless to say the saw has been getting a workout...and me, too. By the time we're done, I should have almost a 2 year supply for my outdoor wood furnace.

I think I know where Fish gets his "self tapping" screws idea from. He probably saw a T after a bolt in an IPL, and assumed that meant "tapping". He probably doesn't know that Stihl uses #27 TORX bolts for nearly all its fasteners...heck he probably doesn't even know what a Torx bolt is.

No, if you morons would bother to look at the parts lists that I put up, you would see that STIHL calls them "self tapping screws".

Are you kids serious?

Yeah, just for giggles, I had my local Stihl source for my e-bay store print this out. He hasn't ordered a ms311/391 yet either, so I have not really seen one, but it sounds like the parts will move well, so I will probably get some this fall. But anyway, looking at it, the screws are not included in the starter assy. which would indicate that they are not "captive"..... Also, looking at the reference number 13 for the cover screw, the description even actually says "self tapping screw"......

It is getting real hard to find an actual machine fastener on any still unit, as they are zipped together at the factory quickly. And if someone removes "said" fastener daily, he is askng for trouble......

Look at the description of part # 13 and #15

OK, here is an ipl copy of the Top cover.

If you get the top cover by ordering it, it comes with the left front screw only!!!

But you will notice that the screw is Stihl a self tapping one.

The other two are generic/likely and included on another lookup, but I may be wrong, of course.......

As you all know full well, I usually am........View attachment 22077

# 5 describes itself as a self tapping screw here too.

You absolute moron, the T-27 is the tool that fits 99% of the modern fasteners for Stihl, but the threads and pitch/and whether self tapping or what, are totally different. I am sorry, but you are a moron.

Something must be up here.....This is the most inane discussion that I have ever been drug into... I know Carsacw, but he isn't that intelligent....

OK...If you were smart enough to read the IPL, you would see that item #5 IS a self tapping screw...and it mounts the air filter housing to the base. That is the ONLY self tapping screw shown on your IPL...and it is NOT a normal user service screw. However, if you look at ALL the other screws, NONE of them are self tapping, and any screw that might be in a normal user or serviceable position is a 6MM Torx bolt, which mounts into a steel insert in the frame. Your analysis is 99% Wrong.

Still dwelling on the wrong cover and wrong bolts.

Your pic # 4 shows a screw with no threads left on it, can you take a better pic?????

 

[Fish]

How about a pic of all of the threads???????
