Lifespan of a saw engine

[quantico]

I have no saws that I bought new.. and none of them have high hours. I am careful to clean the air cleaner and saw even on a 35cc homeowner special.

I am just a homeowner, not a pro... but i like using pro saws and the power they provide. Dont know the reasoning of having ten or 20 saws unless your just collecting.. any more than five in my opinion and your not running the saws enough to keep them around.

I am guessing 2 or 3 hours a day of revenue time on a chainsaw is average for professionals.. but if you carry 6 saws on your truck your still only getting 2 or 3 hours a day.

The electronic autotune saws may wake folks up when they can see actual hours per year.. it will be far lower than people think.

If you can really get a few thousand hours out of a chainsaw engine without a rebuild, that is really amazing. It's typical for an aircooled 4-stroke engine in a small tractor to be getting tired at that many hours.

The life span of a saw has little to do with how long will a saw run under ideal conditions. I fail to see a point. I like clone saws and older rebuilt saws because they are the most reliable. Having a running saw when a batch of logs comes up that matches the size for size is priceless. After such job is completed throwing the saw away and starting over is some times the way I look at it. Every body know that there is a high likeliness a climbing saw will fall a falling will get pinched or a production saw will get crushed by a tractor. Thanks

Twelve year old thread indeed. It is tax time and I'm not a full timer, just an ole' timer. This saw and another went through 50 gallons of fuel this year and this one did the bulk of the work. I keep up with my expenses and time.

1995 046 magnum full oem except for piston and only had to change piston because it had a intake flange nut inside the case that broke the piston skirt. Dont know the hours on it but its been getting weekly use since i got it.

Stihl 661 cm computer data:

1,010 hrs, started 12,*** some times, etc, died.

replace with a new saw.

I find the 660’s to be more reliable but none have hour meters to prove it.

I got mine used and it’s well used looking.

It's nice to see some real data.

How does doing a drop start harm the saw in any way. ??

It doesn’t. I have two 100CC super 1050’s with no decomp. My Dad bought them new in the early mid 70’s. I’m 64 and still drop start them. I like the idea of all that weight falling away from me helping to crank it over.

13 year old thread. Good job!

And all of the saws I had running then are still running!

Will normally last a very long time, really depends on how well you take care of them and operate them yourself. (even if not stored properly can do them in)
I have couple that are 40+ years old (one of them was bought new)

 

[Wood Doctor]

A Poulan Wild Thing might last 100 operating hours. A Stihl professional saw will last 2000 hours. Note that the Stihl saw also costs four times as much but lasts 20 times longer. Something to think about...

 

[ammoaddict]

But I don’t run the saws for eight hours straight non stop. I don’t think anyone does.

He was joking Bill.

That's funny. I hadn't even noticed. I rarely look at the dates on threads.

I like the way some guy's add hrs up on there saws- I work 8hr days 5 days a week and only have 2 weeks off a year so that means my saw gets 2,000 hrs put on it a year.
WTF really none stop for 8hrs? Ok yeah we believe you LOL
Don't know why I'm even bothering but say you get 20min out of a tank of gas that's 24 tanks in 8hrs but no time is taken off for refilling the saw? Or sharpening or time taken to walk move to cut timber no time to do anything but cut.
They must just stand in one spot all day with someone dumping logs in front of them to keep cutting every minute of an 8hr day and not to forget the magic gas tank that never runs dry lol

Yeah my 661 usually lasts for 40 to 45 minutes per tank of fuel...??

You must put 3000hrs on a saw a year then?

 

[rogue60]

I stand by what I said you will never see any pro Mtronic saw ever hit 2000hrs in one year It’s physically impossible!

Once manufacturers started using plastic caged bearings the life hours went way down, these newer auto tune saws have hour meters and start cycle counters. I have seen a few examples of the auto tunes that show around the 900-1200 hour mark its time to install a new piston.

My guess has always been for larger saws above 60 CC to be about 1500 cords. That would relate to about 2500 hours. For smaller limbing saws 1500 to 2000 hours. For the last twenty years I’ve only cut firewood full-time. I have a few 056s that have been going for forty years. Often during that time some thing will happen so it gets a bearing replacement or some rings. I have always had numerous saws so one saw never gets used more than twenty hours a week. So if a quality saws gets used heavy it can accumulate 1500 hours in ten years but not more. I remember I had some smaller saws like a Stihl 011 that completely wore out with about 1200 or maybe a little more over a fifteen year period. It was very well cared for. It was used heavy because it was not a high RPM engine which was more comfortable. Thanks
