jonsered not oiling enough

KUBOTA OWNER · Nov 4, 2010

I was wondering if any one has come across a problem with my cs2145s jonsered, saw is like new but does not seem to oil enough. I have removed the bar and it is not plugged, ran saw with bar off and it seems like a good amount of oil was coming out. everything looks like new. With the bar on it seems to run off the bottom, but not a lot makes it to the bar. even without cutting (semi-loose chain) the bar seems to get warm, cutting after ten minutes its too hot to touch. Looking at a parts manuel a 2150 has an adjustable oiler is it possible to replace my pump with one from a 2150?

Bars will get too hot to touch very quickly even with good lubrication. Is it smoking, etc?

Also you're saying that there's oil dripping down/out the clutch cover when everything is properly mounted??

How much of a tank of oil do you go through in going through a tank of gasoline?

If you hold the saw above a flagstone surface or something similar (maybe a drier stump), and hold it like 2/3 throttle for 15-30 seconds do you see overspray????

You can replace the 2145 oiler with the adjustable one from a 2150.
It sounds like either the bar is wrong or the the bar groove/oil hole is plugged.

Screwed around with it again last night, bolted on the bar no chain or cover.
Run and watch and the oil channel will intersect the unused adjustment screw hole in the bar slightly. When running oil will run out of the hole rather that feeding to the bar groove. --problem solved right? plug up the adjustment hole that is not used until you flip the bar over. So I made a small rubber plug that I can switch when flipping the bar. --the saw is second hand but is so new that you can still read printed jonsered part no. on the bar.
--getting late can't fire it up. --So when trying to sleep I keep thinking about my fix. Then it dawns on me that it does not make any difference if the "extra" hole intersects the oil groove because the clutch cover will close
off the unused top hole. -- back to page one???

It would be much more effective to make shure the bar oil hole lines up good to the supply channel. I had problems with a few Stihl ES bars on my Stihl saws, the oil supply holes needed a little modification to make them align properly. Running them just thge way they came and the bars were getting too hot, burning the paint off the rails in from the edge about an inch before I figured out what was going on. Your bar may be an original one but it would be best to check out that oil hole alignment.
