Loose Chain Problem Stihl

[Fellin Feller]

I have an old Stihl MS362. It ran fine last week. I sharpened the chain and ran it today. The chain gets real loose after a couple minutes of cutting. I tightened it several times and still gets way too loose very quickly.

I'm trying to figure this out. The sprocket seems to have some side to side play in it, is this normal? I am about due for a new bar, but am doubting if the bar would cause a chain to get that loose. Any ideas?

Put up a pic of that sprocket. It sounds like your problem.

is the tensioner still in good shape? It sounds like the threads on the tensioner could be worn and slipping.

I will check that, but don't think it was slipping.

And the bottom tangs of that chain.

Put up a pic of that sprocket.

I will when I get a chance.

would bad needle bearings cause this?

I was t sure if it was “still” a problem or if the “Stihl” had a problem.

Okay, now to suggest the cheapest, easiest possible solution.

have you tried putting a block of wood under the bar nose ?

Put a block of wood under the bar nose when you adjust the tension, and tighten the bar nuts. Use a block big Enough to put pressure on the bar nose, this will put the bar in the position it will be in when being used. It may not seem like a big deal, but it can make a difference. I had a couple saws doing the same thing, and a Logger told me to try that, PROBLEM SOLVED.

Later when I LOOKED, I found that some of my Husqvarna Owners Manuals, said the same thing. Hey, I’m a Guy, and don’t need no stinkin’ manuals (SMH)

chain oiler working ok ?

Remove the bar you may have dirt between the bar and case/clutch cover. Scrape it clean.

Always tip the saw forward on the bar nose when adjusting and tightening the chain

A wore out sprocket is the most likely cause.

Adjuster does not keep the bar tight, that would be the bar nuts.
