Stihl ms231 oil to chain

[aidank]

My Stihl seems to be leaking oil rather than putting it in the oil hole in the bar and onto the chain.

 

I saw the chain give a puff of smoke last time I was using it so said I would investigate.

Is this a new saw, or one that you’ve been using for a while without issues?

 

Don't ask me how I know…but if it’s new and you’re not getting oil fed to the bar, your oil is too thick, like the Makita crap that caught me out when I bought an MS391 after running Makita DCS prior. 
 

If it’s an old saw or you’ve not changed the bar oil type I can’t help you brother. Guess would be a blockage or something. Check out my thread when my MS391 gave me hassle right out of the box.

Long story short, put some piss thin bar oil in and try again.

Plastic gears stripped that runs the pump ?

Its 7-8yrs old, not a lot of work done, 300tanks of fuel gone through it.  Most needy item I have ever come across in my life, carb seals, difficult to start, pull cords, difficult to tune the carb, its been back to the repair shop a few times.  Fine powerful machine however.  No advertisment for any brand, I wouldn't buy it again, I would buy a Japanese saw.  

Japanese hedge trimmer and leaf blower here, much easier to start, never give any problems.

 

 

Nothing wrong with oiler or the oil, both are functioning perfectly.  the oil is leaking rather than going into the hole in the chainsaw bar.

I have marked up my photos with a red line.  To the left of the red line the plastic chainsaw body housing seems to have been eaten away by the chain somehow.  

 

And Im looking for suggestions on how to repair.  Probably not the first to have this problem.

Repair not really possible as it's eaten the plastic housing.

 

Most likely cause is a loose bar/chain allowing the chain to wander left/right on the sprocket.

 

It's one of the reasons they moved towards rim/spur to limit that wobble, well in my hours on saws that's what I found.

Clean it up and build up with JB weld or similar or some hot melt glue.

Something I have done is make a paper or cardboard copy of the bar, to help see what's going on, whether the holes line up and why its leaking.  Clean out all that oil first. You could try opening up the oil hole on the bar to persuade the oil to flow.

 

The whole white plastic clutch cover looks like it comes off with hex screws.  That will help you see underneath and whether the black oil line can be replaced

I had trouble with my MSA 220 oiler a few months ago. Search my threads here. See if any of that seems likely. If it does, @ tag me in this thread. I have a 230 here. Can probably walk through it with you.
