Jonsered 2159 oil output issue

[subhunter]

Hello all. Here is the story with this saw. I got it at a steal of a price recently and had to replace the clutch.That was all that was broken on this saw. After running several tanks through it I have come to realize that it just does not oil like I like them to. I have TRIED several things to address this issue.

So far I have swapped out the oil pump with two others,one off a 346 and one off a 350. I have used the 346's worm and used a .325 bar/chain and then also the original worm and 3/8 chain.(The oil pumps on both the 436 and my 350 had the exact same part # as the oiler on the jonsered) With the bar and chain off the saw does spit some oil and puke some out so it is trying. Once the bar goes on it ,it just is not up to par. Now I am fairly certain that it is the correct bar, I have had the {346} 18" and a different 20" on it. I then bought a 20" b/c just to run on this saw as it is the 'medium' mount husky. Still not enough oil.

Yesterday I took it all back apart and completely took the oiler apart and cleaned it back up. No change.....

edit:Also did blow air through both lines and cleaned the oil tanks pickup filter

What gives? I like to see the oil sling off the chain and this one is far from that.
sorry for the long post just trying to get my fleet back in operation

You are experimenting with both the pump and the bars and chains, but the first thing to do when dealing with an oiling issue is to determine which is actually giving you the problem. Easiest way to do this is to run the saw with no bar on it. Either it's pumping oil or it's not. If you are seeing plenty of oil, then it's a bar issue. No oil, then concentrate on the saw.

You've mixed a lot of different parts from different models. So I'd say go back to square one and get the proper 2159 parts on the saw. (The 346 and 2159 oil gears have the same thread, ID and depth, so that didn't hurt your experiment.) One thing you might do is to remove the oil pick up tube and blow it out and make sure the screen is clear. Also check the oil tank vent.

Thanks spike for your reply

I had to add that yesterday when working with this issue I did remove the pick up line and blow it out and the filter is clean. Also I am thinking that either oil pump would work as they all had the same part # stamped into them. The original pumps only defect was a small ear at the back of the pump, stops the adjuster screw, was broken off. The other pumps was not. With no bar on the saw it will puke out a small bit. With the bar on it you can see oil but not too much.

The only thing I have not checked is the vent but where is it. To my untrained eye it is not visable....

My research has found the 2159 oil pump is not the same part number as the 346xp or the 350 oil pump. Purchase an oil pump that came off a Husqvarna 357xp, 359 or Jonny 2159, or a Husqvarna 455 or 460 saw. The oiler gears need to match the oil pump.

When we got the 2159 some early ones had oil issues due to the oil line being improperly installed from factory. If memory is correct oil line needed to be rotated to match up. Been a long time ago, may be wrong. Will check IPL.

 

[Stihl Crazy]

If you look at the IPL for the saw you will see that the oil lines are "C" shaped at the ends to fit around the end of the oil pump. Some saws came out with lines rotated 1/4 turn not making a proper seal with the pump.

Thanks for doing some of my homework

My research has found the 2159 oil pump is not the same part number as the 346xp or the 350 oil pump. Purchase an oil pump that came off a Husqvarna 357xp, 359 or Jonny 2159, or a Husqvarna 455 or 460 saw. The oiler gears need to match the oil pump.

I never thought about it but I guess that some one may have cobbed it up before I got my hands on it. I never did research the real numbers for the 359, which is almost the same saw. I had just compared the three oil pumps I had on hand, which all do share the same part #. NOw off to get a new pump I guess.

Low and behold

I went to my neighbors,the guy who 'runs' a tree trimming company. Found a trashed husky 460 in his shed. It is about a year old. I robbed the oil pump off it.Can you believe that it has the same part number stamped into it. Now I have 5 oil pumps, 5 saws {2x husky 350, 1x346xp,1xhusky460 and a jonny2159}.

I also noticed that the oilers are actually oiling some on the Jonny2159. The problem is where the pick up hose and the out put hose squeezed together. The oil seeps out behind the plate that covers the oil pump only letting about half,maybe, come out. The newest oil pump even though it is stamped with the same part # actually has a tit on each side to allow it to seat in to pick up and out put hoses. I will take a pic later to show the tits :msp_w00t:

I find it strange that even though every saw I have ppulled a oiler off of has a differnt part # per IPL but each saw was holding the same pump. These saws vary from, well one of the 350's are from 1998 the other 2005. The 346xp is a NE from 2008, strange if you ask me.

Also I noticed that the only other difference is the 350 saws have a pickup/discharge that slip over the end of the pump. The others all had split pickups.

I left the 346's pump out of the picture as I didnt want to take it back apart. I plan on using it later as well as this jonsered to see if the 460 pump helped it out.

Just had a spare second and hit up chee bay and typed in 'husqvarna 460 oil pump'. Got a hit where we can see the part # on the ad and in the photo.

Crazy how they confuse us like they do. Seems like this pump has one ID number on the bag, but stamped into the part is a totally different number. Also seems like the same oil pump can be used on many many models of saws...

I have changed the angle on the pump piston and it works great on my 346xp

Yes thats all you have to do to get more oil out of the 346 pump. I used to just replace the piston in the pump with one from a 357. After you look at the two side by side its not hard to figure out what to do to the 346 piston.

I'm thinking that the number stamped on the housing is the part number for the housing alone, and probably only used in house. The guts of the pump are slightly different and that is why the assembly has different part numbers. Either way it sounds like you should have your 2159 pumping properly.

I'm having similar issue with my cs2165turbo saw. I've limited knowledge/mechanical aptitude. That being said do you know where a guy can find a schematic for this fix or a diy oil pump replacement video?
