Loosening screws

After rebuilding my 365 into a 372XP, I got maybe 10 minutes of operation before a couple of screws came loose.

I'm inclined to reassemble with Loc-tite 248 (blue paste) since the threads are small but I'd like to hear your individual recommendations.

I use blue locktite ... Seems to work just fine !

 

I use blue loctite all the time.

 

Yes, blue loctite is anything with a motor's friend. Even small screws. Just don't use red on the small screws, unless you're a sadist and like drilling and retapping and swearing a lot.

 

I always use rtv silicone, never a problem.

 

I like the silicone idea.

As for loosening screws its a husky. Hideing under the table now. I have a husky and it chronically looses bolts. The recoil assembly seem to be the worst offenders.

 

I forgot about the pink stuff. On the small screws I only use a tiny amount of blue applied with a toothpick to a small area, and I don't coat the entire way around the screw. That method works the same as the pink stuff that not many people have. But if you have pink, use it.

 

Never heard of pink. But I am not a guru in the various goops and such you get for various tasks.

Thats good to know though.

 

Pink/ purple, nearly nobody knows about it or uses it. I learned the trick with using a tiny amount of hours through work, but I've also seen "blue threadlocker" on tiny motorsport screws on carbs linkages sensors etc , that had full thread coverage of locker, but those screws are usually torx or better head types than phillips.

I've heard about folks using silicone sealant on items like this, I've just never used it for that use.

 

Ive never heard of the silicone idea ! Does it work good ? How bout when its time to unscrew ?

 

I have used the blue rtv on bolts and not just on chainsaws. It works fine and breaks loose fine but it can be a little gloopy on the threads and takes a little bit to clean them off to reapply. Good in a pinch. Usually use blue locktite.

 

I use red loctite in stick form on all my Huskys... It's a steel to magnesium thing... I've not had a problem getting them back out..


Yet...

 

I just went over the saw using a bit of the Loctite blue 248 goo stick. Hopefully tomorrow i can get back to cutting.

 

You don't have your screws tight enough if they are backing out. Look at the screw when it comes out. If it had some sort of retaining compound on it, then you probably need to re-install it the same way. But save the cylinder bolts, very few saws will have anything on any of the bolts.

 

Replace all screws with T-27 torx (like a proper Stihl). Thereafter, if you need it, Blue Loctite works great.

 

Huskys dont like being screwed by a Stihl

 

You are mixing a Torx head which simply means the type of tool needed to fasten/loosen with the fact that Stihl fasteners are serrated on the underside.

 

Glad to see a sense of humor around here.
