The front stud is screwed into the plastic bar oiler container and has been coming loose since I first bought the saw. I have purchased an oversized screw and made the repair but this oversize stud still comes loose. My question is is there supposed to be a thin plate between the bar mounting surface and the bar? My 028 and 066 has this thin plate but I can't remember having one on the 029. I would really appreciate someone giving me an answer telling me if I need this plate which is very thin sheet metal. Yes I did strip the stud out of the plastic because of overtightening the bar nuts. As an engineer I would never have designed a stud to screw into plastic.

Why didn't Stihl warn buyers of this saw about this problem? They obviously understood that they had this problem because they designed and put in stock an oversized stud for a fix for this problem that they had to know about. They would not have a fix unless they knew about it. The oversized stud does not hold nearly as well as the original stud and I just tried a locktite product that is supposed to work on thermoset plastic and steel. I think Stihl should assist their customers with advise on how best to fix this problem. But they know that if they get too involved they will automaticaly have to accept some responsibility for something they want to keep hidden from the public.
Anyway thanks, Jim. You mentioned an over size stud.Stihl does not have an over size stud for this purpose. I suspect you have used the stud which comes behind the one in question. The one behind is a longer one and screws into the engine pan. Since it screws into metal, it has a finer thread. The stud with which you have problem goes into the polymer body and has a coarser thread.
This stud comes loose only due to the following reasons: 1. Using the chain cover nuts ignoring the inner and outer surface of the nuts.When put correctly the nuts turn freely. But they go in tight and come out or even tighter when put the wrong way.At times the studs come out with the nuts when this happens. When both nuts are not tightened evenly.The stud carrying the slightly loose nut gets moved around a bit and loosens in its thread. Over tightening of the nuts. Using the '2 nut' method to put the stud back into its thread.There is a special tool for putting in the studs. Tightening torque for the stud is 16 Nm.
Loctite 243 (medium strength) should be used when fixing the stud. Friend Joe Indi; Stihl does have an oversize stud as a fix for this problem. I don't know why you would say they don't have one because you are absolutely wrong. I have one which I had to buy from the Stihl dealer. The coarse thread is larger diameter and is meant to screw into the hole after the hole has been stripped from the smaller dia. Coarse thread. Why did you say they don't have an oversized stud for a fix?
Are you some kind of a spin meister for Stihl, lurking on this forum? Lets all be honest and we will all be better off. I will get the part # and post it if you continue to deny it. Maybe you just made an honest mistake but you came back as if you were a Stihl representative and I was a farmer mechanic who did not know what they were talking about. I hope you will answer this as I am curious as to why you made that statement. 16 Newton Metres. I have owned Homelite EZ4, McCullough, Mall, Stihl 031 & 032AV in the past.
1958 I was cutting pulp wood on the Ausable river between Glennie and McKinley, Michigan. I have worn out a few saws in my 72 trips around the sun on this beautiful space craft called earth.
I presently have a 066, 028 and a practically unused 029 that is practically unusable. I hardly have enough strength anymore to zip my fly let alone over torque a bolt.
I guess I did not realize all these years that I needed to use a torque wrench when taking the slack out of my chain. Seems all wood cutters should carry a torque wrench on their belt when working in the woods. Does anyone know the part number for the torque wrench I need so I can buy one at my Stihl dealer. Any honest advise will be respectfully appreciated. The Stihl technical bulletin number for this problem is: TI-14-2000 The part number for the o/s stud is: 0 The old stud is an M8 coarse thread The new (repair part) stud is an M9 coarse thread The bulletin advises locking in the new stud with Loctite # 648 The torque spec for the new stud is 16nm I have used this repair and it does work, but I can see where a much oversized hole might be so loose as to not grip the repair stud tightly enough.

I can think of a few repair ideas for this, but. It's always better to have seen the item first hand before offering a repair opinion I'm guessing that with the saw being an 029, it must have a few years on it. If it's in good shape otherwise, wold you consider buying a used housing and replacing the worn part? It would be an ideal time to reseal the crankcase and wouldn't cost much extra - just a couple of seals and a tube of Dirko. John (Stihl master tech) edit: Jim - you posted while I was typing (slow typer) - would you like me to see if my former customer/employee/partner/employer (whom I sold my company to) has a used housing?
My knowledge of saws is self taught, mostly through experience of the past 17 years, not through any formal degree or technical education. OK, I do have a degree, but its for Hotel Management!I did run my own restaurant for 6 years before I switched occupations. I liked to handle engines from my early childhood, and the present occupation gave me a chance to continue doing it. When I need to get information which I may not know due to my technical inexperience(deficiency) I check the Stihl parts list on cd rom (Mediacat).I have the most recent one. As per this spare parts list the only stud available was part no.1127 664 2400 i.e. The standard collar screw (stud).
Today I also saw John Bartley's posting. I did a search in the parts list for the over sized stud ( part no.1127 664 2410).It was not there in the parts list. But TI-14-2000 was very much there.Honestly I never knew of this alternative part.Since John too seems to be working off the Mediacat, he could do a search of the parts list to confirm what I've said. Since more of 660s and 460s are sold here, 029/0390 (MS290/390) are few on the ground. When they do come in with their engine housing thread stripped like in your case, I resort to installing a gun metal threaded insert which can take the 8mm stud of a 046. I hope this clears any doubts that you might have about me being a Stihl 'henchman'.
But if my postings seem to put you off for being too categorical,a habit picked up in my restaurant days when writing recipes, I do apologize.
