3120 filter cover vibrates loose

[U&A]

3120xp ported

Is it normal for this saw that the filter cover keeps unscrewing from vibration? I mean I really really have to crank this thing down tight to get it to stay put. I’m afraid I’m going to hurt the threads over time. Been doing this for quite some time. I just figured it might get better after use but it hasn’t

Usually if it comes loose it’s within the first 1 to 2 cuts after the filter cover been off. And it comes off so darn quick when I’m in the middle of a cut it’s darn near almost falling off

Anyone else have this happen?

As often as you remove and replace the cover, use thread lock?

I get it, purple and blue are the lighter duty thread lockers. Guess ill try it.

Thank you sir

Dont need a lot, just a bit in one spot to stop it coming out.

After you use it a few times, residual locker will hold it in place. May have to reapply a few times.

Its the demons trying to come out.

Make sure the 2 bolts in the tray and 2 under the foam are tight. Tighten the muffler bolts too. Maybe something else rattled loose and is causing it

Cylinder bolts tight? Locker?

No gasket. Motoseal with some residual in the bolt holes. Doubtful, but entirely possible

Try dropping the tune down 500 rpms maybe. See if there’s a different feeling in the hands

That Motoseal is some sticky stuff. Use it with a gasket and may not need bolts.

When I first tried it, I thought it was too runny. But it works, so....

Check them often too. All good


EVERY BOLT that can be reached with all the plastic and such off gets checked after a full day of use.

I let it cure for 24 hours, what is your process? Also clean both surfaces with parts cleaner.

Ill bring it down a bit and see if it still does it.

I clean both sides with carb/brake cleaner, apply sealant to 1 side, and bolt it down ASAP. Then I do carb, ignition, and muffler mods. So probably 3 hours or so after bolting the cylinder down I start them up
