help with bar oil pump

[Muddy42]

Thread revival / update! 

 

So by chance I managed to find a second hand high output oiler (part number 11286403250).  This is sometimes called a 1:1 oiler, meaning it uses 1 tank of oil to 1 tank of fuel rather than about 0.8 of an oil tank.

 

I used the saw for a few hours yesterday and I can confirm this was how much oil it was using.  I am a bit cautious about letting it run out of fuel/oil totally, for obvious reasons, but the saw was oiling even better.

 

It seems really odd that this saw needs extra oil for a 20 inch bar, but if thats what it takes to avoid the bar nose seizing up, I dont mind.

I've got some issue to investigate on the 372! If I hold the saw horizontal to cut a slice from a stem I was getting a lot of smoke and noticed oil was visibly squirting from the bar mount area, directly to the exhaust.

Cure was to flip the saw over. I didnt notice after that if it was still squirting out. The bar appeared to be getting adequate lube and cutting fine, though I didnt bother to test if it flings from the nose.

 

Its had a good clean and will try again tomorrow. Any ideas if it continues? I did have theboiler turned up to full, might need to turn it down.

Can you clarify what you mean by oil squirting "from the bar mount area, directly to the exhaust"?  For me the bar mount area is on the side of the saw and the exhaust is behind this.  Oil should stay on the bar mount side and it shouldn't be possible for bar oil to squirt onto the exhaust.

From the top of the bar area, a good squirt was shooting out every second. With the saw held with the recoil side downwards, gravity had it landing on the exhaust.

 

I'm about to fire her up, if its not cured by yesterdays cleaning I will try to get a video.

OK thanks I understand now. 

 

If its squirting only when the chain is moving, my guess would be there is nothing wrong here just excess oiling, which you could turn down. or oil is too thin.

 

But always worth checking.  Sometimes the bar or faceplate can get dirty or dented allowing oil to leak out in strange places. Normally though oil would just leak downwards to the chain catcher area

 

You can make a paper copy of your bar to check the alignment of the bar hole?

 

You could run the saw gently without the bar off to see where oil emerges from the body of the saw.  The risk is that the clutch flies off, so I do this outside, pointing in a safe direction and after the saw is warm so it doesn't require much revs.

Is this a genuine 372 or a Farmertech clone ?

All solved by cleaning, she is running great today.

 

Yes Stubby it is the Farmertec.

Irreavent what saw it is then ! Well sorted . 🙂

I lied about running great. Early on the recoil spring snapped, likely user error as I have had to adjust it before. Anyway after bending a new tang on the end and she was fine after that. I'll get a new one ordered along with spares for my 020t and 2511.
