Stihl chain keeps coming loose

[Huskybill]

Just kidding bro. I heard rumors that the Stihl quality has changed from when they were made in Germany. Even huskys have there quirks, as long as the saws run when I need them.

I purchased a so called running saw that had more problems than what it was worth. Really abused but looked good, clean. Between the parts it needed and my sons time to fix it. It’s a keeper now, but I’m impressed with this low budget homeowners saw. Husqvarna 350. (13,000 rpm right up there with the pro saws)

Now I see what the guys who port these saws are talking about.

I love drilling holes in the magnesium, and putting a match to the drillings.
Pretty light show!!

Ive replaced the sprocket and the stud, after cutting 3 logs the chain is dangerously loose again. Any clues?

Is the oiler working? No oil = hot chain = longer. Don't tighten it when it's hot, when it cools it will place a lot of stress on the bearings and studs.

Oiler is working well, can see it coming out. Didnt tighten anything when it was hot, tightened it before i used it.

Hmm. If you just leave it to cool, does the chain tighten up again?

Negative

Odd. Either the chain is wearing extremely fast, or the bar is slipping despite the studs and tensioner. I can't think of any other way.

Actually looking at it the oiler does seem quite pathetic. How hard of a replacement is that?

The bottom drive links of the chain are damaged, and will quickly damage the new sprocket.

Mike this is a homeowner saw with only one stud so you can use the quick adjust. This may not be a quick adjust but one stud (in plastic) never the less. Maybe the owner could ad another stud, if the cover (again plastic) has two holes.

It is a 1 stud saw and doesnt have 2 holes sadly

I'm noticing that there may be an issue with the oiling gear under the clutch now. Seems like I fix 1 problem and 4 more appear. Not sure how someone can ruin a saw to this extent honestly

Take off the chain and take a good pic of it.

Try to remove some of that flakey **** off so we can see the metal.

Also, laying on the table, take a length of 10 links or so, and pull the length apart, then push back together, and see what the difference is, you might see a bunch.

Also snap a pic of the new sprocket, so we can see if there is any marring.

Have you gotten the side cover to seat properly?

Seems to, does seem like ive got some rubbing when I move the chain though, im going to take a video and some pictures that harley requested

It's always hard to diagnose at a distance, and from photos. I am sure that someone over there familiar with STIHL saws could take a look at it and tell you what the problem is.

But with that comes cost
