We shouldn't worry if are chain is hot
After all most cram them in the ground at wfo. Lol
A sharp chain that self feeds will be cooler.
It's easy to tell what kind of chsin the owner keeps when you take his saw apart.

Explain further Jason. What is different? Bad bearings of you put lots of down pressure on the bar? Vice versa?

 

[TreeLife]

Probably evidence of overspeeding the engine, when the chain is ground properly the saw will work at a much lower rpm. Cylinder/piston wear would be evident

 

[jmssaws]

The plastic around the clutch is melted or discolored and the clutch and drum are blued and the saw is covered in dust.

 

[jmssaws]

The heat from a less than sharp chain soaks the bar and passes it on to the crankshaft and then the bearing and so on.

 

[RI Chevy]

Interesting. Thanks for the explanations.

Its like a little F truck
Hire car while I wait for my new work truck to show up

Man pics of the truck please

And speaking of derail the HF temp guns work good at close range ie at 5ft and less and for looking at the internal of motors $11 shippedfrom ebay its pretty slick

I'd like a boroscope. Faster than taking muff off to check for scoring.

What temp should one be looking for on the muffler with IR thermometer to start worrying about scoring going on inside?

Clutch bluing and plastic melt I solve that by running sharp chains.

First thing you should do is learn to sharpen when new at this. It's a good skill and can be done quickly as you get better at it. Make sure you are able to do it on site / in the woods. I take two chains for each saw and 2 or 3 saws the second chain is for total chain failure,. Multiple saws so you can stop once if sharpening needed. It's the 2 or 3 saw plan so you can have a productive day cutting.

If you can't sharpen then you have to take many more chains when doing yard trees!

I've seen 650° on the cylinder side fins.

 

[RI Chevy]

Yikes.

 

[mdavlee]

Yikes.

They get warm after 6 minutes of cut

 

[RI Chevy]

I bet. I am surprised that the thin mufflers can take it repeatedly, over and over.

They do Crack eventually.

Sounds like you had it happen a time or 2. Lol
I guess that's why they sell parts.

 

[mdavlee]

Got several that are cracked and I've welded some up. They all wear out. The 660 dual port ones will Crack the bracket off the front after a while.

 

[RI Chevy]

Wow. Is that why you put the exhaust port in front to help rid the heat?

 

[jmssaws]

Hottest I've seen is 400 degrees on the fins
That was a 235lb 066 after a 30 second cut.
In a few seconds it would cool to 200 idling.
They cool way faster than I thought

Temperature drops very quickly. Less than a minute and it wouldn't melt the 400° temp stick.

I use a front outlet since it's the most direct way out.
