MS441 front AV grinds hole in case

[irhunter]

I have a 441 project. The front AV spring has ground down an area of the case...headed for the oil tank.

I am shopping for a case for this saw. For reasons other than the one I'm posting about. All of the cases I see for sale have similar grind marks.

I suspect running the saw with pooched front AV causes this. But, it seems common.

Anyone see this while running with good AV? Maybe it is the nature of these saws without the stiffer wrap AV springs?

Either the wrap handle is bent, AV screws are loose, or the spring is worn out

So, I have my case, one on Chainsawr, two on ebay...all have the same damage.

I guess one might say, People with saws which end up being parted........

Anyway, maybe what I am asking: correctly-maintained, stock 1/2-wrap-front-AV, won't end up causing this?

That being said, I wouldn’t think so. The springs must be a little bit soft. I’m not certain, but a 462 or 661 front spring may work

Stihl makes a stiffer spring set for this saw which came with the full wrap version.

But, if the stock springs, but with new bushings, will not cause additional damage...I'll go that route.

The av bushings wear out pretty quick, I actually used a black rubber one in my full wrap 441 to keep it from rubbing.

Black rubber ones from some other saw?

New AV springs and quit pushing so hard. Let the saw bar and chain do the work.
