First time posting. I am a firewood guy. My first (and only) saw was a 450 rancher. Bought it in 2012 and have cut about 50 cords with it. Have always run 50:1 ethanol free and generally taken care of it.

Stopped oiling this spring and a new oiler was only $50 (parts and labor) at the saw shop.

Now it has a different problem. Oil pours out (from the correct place on the saw) as fast as I can pour it in.

Not sure if I will try to tackle this myself or go back to the shop. In fairness to the shop I have cut 3 cords or so since the repair, so i am not blaming their work.

My larger question is what is considered "high miles" for this saw. I don't mind a little maintenance, but if its time to bite the bullet (and get that 50cc pro saw) I would like to know. Is there a rule of thumb for normal life?

Thanks in advance.
 
Many saws if cared for will run 1200/2000 hours. Just run good oil/gas keep air filters and intake boot, and all fuel lines and seals (crank specifically) functioning as they should. Your little husky has tons of life left just be cognitive like you appear to be already, about how it’s running. If it starts idling funny, bogging or hard to start then diagnose the issue at the moment without continuing to run it. Grease the crank shaft, replace the needle bearings and rim and sprockets when they wear.
 
Little update. Confirmed that oil poured in is leaking from two places. First, the correct place (and it gushes out) and second a hole near the bolt for the clutch cover. So probably there is a line disconnected.

I read about removing the clutch to take a look, and everything I read (or watched on YouTube) showed that force was required to loosen the clutch. Well, my clutch can easily be spun in the off direction...but it doesn't come off?

Confused newbie. Ideas? Or should I give it to a professional?
 
Not sure how the oiler on a 450 is set up but bet the oil pump is leaking plus the output line is split. You'll need to pull the clutch and sprocket to het at the pump. Once these are off replacing the pump and output line is fairly straightforward.
 
Just how do you do that? I have been working on saws since 1987 and have never done that. Maybe I have missed something. Mike
Eeeek I meant to say clutch bearing or the drive sprocket! My bad. Use a bar tip grease tool.

Here’s what I ment. Sorry for my jacked up terminology Rupe.As you can see, it is in fact the crankshaft.

 
Well, my clutch can easily be spun in the off direction...but it doesn't come off?

You are turning the crankshaft with clutch. Crankshaft needs to be immobile. 2 ways:
1. Rope in plug hole to stop piston. Wrench clutch CW.
2. Air impact hammer with socket turning CW. Don't even need to stop piston.

Search youtube - remove a chainsaw clutch.
