Sprocket life expectancy...

[spudulike]

So the problem with a few years chainsaw production is the metal the drums are made of.....it isn't like Stihl haven't made a few million chainsaws in their time

So what's the excuse with the MS362? I have had quite a number in now with the same issue! Funny that I have never needed to change a bearing on a MS200 and 066/MS660s seem to go on forever

Well Mick, bloody good clean , new tank  filters , poss new AV mounts, mebby a piston clean ( not usually needed with these cleaner 2/ oils ) an good check over , K

Don't know about any other model but this was the reason changing to a spur sprocket was effective if caught early enough ie before the drum destroyed the bearings and wore the crank.

My old rule of thumb is,

3 files to a chain

3 chains to a bar/sprocket

3 bars to an overhaul.k

 

( to guys who think the bar should last the life of a saw- but then in their hands that's usually 1 8months ;P )

Three chains to a bar? I think that is way way out tbh.

 

I have no clue what it is as I just change the bar when it is worn out but I guess it's closer to thirty than three.

Ok thanks, I can’t see that those things are necessary, if it works fine keep on keeping on.

 

Cleaning? Apart from blowing off crud what is there to clean?

AV mounts? If it ain’t broke don’t fix it.

Piston clean? Never done it.

 

Here is a thread I started on just this subject...

Near 30 chains? Really?! I average six or seven (not including the old playdough husky bars), chains last 3 to 5 weeks of mostly forestry based felling, but depends on species/ ground. (you using an angle grinder on the chains?)

Well Mick, if yr company is hot on HAVS, it's a good idea. Those mounts degrade silently. A worn bar wont cut well and in forestry snedding it kicks the arse out of the rails. K

Fair comment on the HAVs.

 

re. Guide bars, they get replaced as and when.

 

I suppose a lot of it is that real forestry and tree surgery (which is what we do) have different demands on saws. Ours don’t work half as hard (and neither do I!):)

Plenty of life left in this one!
