Husqvarna oiler problems

My Husqvarna 450 rancher is still having oiler problems. I replaced the ring gear around the shaft, the oiler pump piston and pump cylinder and oiler hose with husky oem parts. When i spin the clutch drum fast I can see a little oil come out. When I put the bar back on ant run it no oil sprays off the chain. I have blown air through the oiler hole on the bar and it is clear. After running the saw I have a little puddle of oil underneath but it doesn’t seem to make it to the bar. Any ideas?

 

Is your oil tank clean? Maybe poor a little gas in empty oil tank to thin things out and swish around before poring out. Might have wood chips/dust monkeying things up.

 

What I would do in this situation, put the bar on the saw without chain. Start the saw and with a good flashlight, look down in the groove where that oil hole is and rev the saw a little and see if oil is coming into the groove. What I have done in the past, clean the bar really good and the rubber hose area that touches the bar when it's on the saw. Then smear a little fresh oil on just thr rubber and carefully press it to make a witness mark to confirm where on the bar the oil is being pumped. I've attached a pic of when I did it.


This will confirm oil has access to the bar hole.

 

Have you cleaned the groove in your bar? I take a flat spatula patching tool or anything thin and sturdy and make sure the groove is clean. Also make sure the hole for the oiler is clean.

Also to double check make sure the bar you have has the correct mount for your saw. I learned this recently on an Echo CS-4600 that requires a specific K041 mount.

 

I will check the tank but am thinking since a little oil comes out when I spin the clutch drum that the oil tank is probably not plugged.

 

Great idea. I will try this and post the results.

 

The oiler hole seems to line up and you can see from this video that the oil pump seems to work https://youtube.com/shorts/Wa2y7GixieE?feature=share

 

How does the drop in oil tank level compare to drop in gas tank level when used? You might be getting proper oiling.
Very little oil comes off the end of my chain when I hold it near something and rev it but the oil tank is just about empty when it runs out of gas.

 

Advice from a pulpwood cutter once: cut the bar oil with wd-40.
There is a screen in the oiler reservior I believe, that could be checked
Bar oil too thick? Cold?
I do not recall if there is an air intake port/vent to the oil res. Same idea as the gas tank....so exiting liquid does not create a vaccuumm.

(Never can spell that word properly)

Does that metal plate sit above the black rubber piece that the oil goes through to get to the bar?
It looks in the first picture that it might be oiling but not getting to the bar??
Perhaps it has been flattened out over time and not sealing on the bar and letting oil just flow out around it.

 

I tried running it without the chain and I did not see any oil coming out of the slot in the bar

 

It looks like oil is pumping but just not getting to the bar. Should the rubber oil to bar supply piece be sticking above the sheet metal cover?

 

Maybe the junk in the clutch cover is preventing the bar nut mechanism from tightening down enough to make a good seal

 

The next thing I've done, if that rubber isn't pressing up against the bar tight, it could be leaking out and down instead of into the hole. I've pulled that rubber "cup" part up and put a little saw powder behind it to get it to stick up a bit to make a better seal to the bar. Definitely not ideal but got me through until I bought a new rubber piece. Too much and you'd crush or squeeze that part of the oil line and prevent flow, so go conservative (if you decide to try it). I'm leaning towards you needing a new rubber line right there. That rubber has to seal against the bar or it's just weeping out the side.

 

With that vid, the plastic oil pump drive worm gear shouldn't be spinning (which in turn spins the oil pump itself) unless the clutch is engaged and, under normal cutting, the chain is spinning. So with bar on, you shouldn't see oil coming out into the groove unless you revved it enough to lock up the clutch and spin that drive gear.

 

I tried putting a little sawdust under the rubber outlet tube and I still get no oil coming out. I have replace that tube and the gear and pump. I can see oil coming out of the rubber tube when I spin the gear by hand. I am running out of ideas to try. Anybody else have any ideas?

 

Maybe MasterMech can give a few ideas?

 

I may have figured this out. I think I might be using the wrong bar for this saw. I replaced it a few months ago and it seemed to fit allright but think I started having the oiling problem about that time. See the pictures of the new and old bar and how different the oil holes are.

 

Paul Dokken, I guess at this point I’d try running the saw without a bar or chain to see if you even have oil being pumped. Should be quite obvious whether the pump is working. Although there appears to be a difference in the size of the holes between the two bars, the orientation of the holes On the bar seems to be the same. Also, if the saw has Oiler adjustment, I would turn it all the way up, so you’re getting maximum oil through the pump. Hopefully this will help you figure out what’s wrong

 

I think this is the bar I should be using . Will chains that are 80 links work with that bar says it is for 78 links?
