Husq. 281 locktite

[JohnAlbers]

I have a Husqvarna 281 that I just took the muffler off to clean the screen. Now that it is cleaned I want to reinstall the cover over the screen. The screws seem real hard to get off the first time. I talked to one person who told me that I need to use red locktite on it. Do you really use locklite on your saws? Thank you for your help.

Look at the threads on the screws, if they have red or blue residue, they probably had locktite originally. There are different strengths of locktite, I've been told by old timers that the lowest strength will hold but also function as an antisieze, so you can get things apart later. I just lost 3 of the screws from the starter cover on my Husky. I probably forgot to tighten them, but if I loose them again, I'll consider locktite.

Be careful, there is some locktite that needs to be heated to 400 F before you can take it apart! I had to get that for a wobble box on a John Deere mower. It was on 3/4" NF grade 8 bolts, they want it to HOLD and watching it vibrate, it needs some help.

The screen is bogus, first thing to do with a new saw, before the screws are heated on tight is to fling the screen into the bush, worse than useless, you don't need it.

If your talking about using loctite on the muffler or anywhere above the bottom of the cylinder, forget it.


Loctite will not stand up to the heat. 300f is the max temp and this is only for short periods.

Unless you are cutting on USFS property. Then you have to have a screen to pass inspection durring fire season.

So I save the screen from a new saw, so when inspection time is here I can install it. After they put that little sticker on your saw, put the screen back in the toolbox.

There are hundreds of Loctite products. 222 is purple and for small fasteners, 242 is blue and medium strength, 243 is the same strength but works on oily threads, 262 is high strength for locking pins etc, 271 is very high strength for large capscrews, 290 is cool as it is a wicking solution for locking fasteners that are already torqued or for sealing porosities. It goes on and on. I use 242 on muffler fasteners. The cylinder temp should not exceed 260 degrees F unless it is plugged up with sawdust or the flywheel cover is restricted etc.

I use either red or blue on anything that can rattle loose and have never had any issues.
As far as your screens, regardless of what some people say keep them in.

yeah........

.........lose the spark arrester. hateful little fellow.

....now if you're cuttin' in the heat of summer, well, it's a judgment call, i'd guess.

...if you're working where it's required, use it. you need not locktite or torque the crap out of these. when ya get home and do your maintenance, give 'em a twist. fore and aft. keep the little bugger clean. hateful. absolutely hateful.

....i reckon these would work, but their surface area is way too small. my old 65 has a huge spark arrestor, kind of a bowl design, has not had so much as one little hole blocked. ever. no need to defeat it.

You get fined around here in "Cullifornia" w/out your screens. Besides ever read in the news about the poor bastard who accidently started a forest fire?

 

[cord arrow]

yeah........

........i read that. turns out dude was drunk and started a bonfire.

my account shows no chainsaw was involved.

I was refering to a few dif. instances not one directly. Regardless the only thing that keeps fire from breathing directly out of three ports of my mufflers is screens.

 

[JohnAlbers]

It was a real pain to try and break those two screws free. It does look like a red material was on the screws when I was able to remove them. Maybe that was the locktite?

[cord arrow]

look sling'r....

......what i'm sayin' here is that conscientious use of a tool in which you're familiar with poses much less of a risk than your average joe in the woods with a book of matches......

......need we google the results, or will you take my word for it...........

i personally would NOT advise using locktite red on anything other than bearings, thread inserts and flywheels. blue covers everything else on a saw. red locktite is some hardcore stuff!
