How to adjust chain oil

SOURCE: husqvarnar model no 345 oil feed problem

First thing check the feed hole through which the oil is delivered to the bar itself for debris,secondly the worm gear turning the pump shafft need only be slightly damaged to hamper full oil flow , next take the oil filler cap off, (with the bar ,chain ,bar plates, and oiler removed ) look where the oil pick up is in the case half and remove it and check for clogging and / or tears in the rubber hose,
if the cap is equipped with a breathing filler cap check make sure the cap breathes this will also hamper maximun oil flow capacity,
I stand by this , as I have dealt with product for close to 2 decades and know it intimately

hi cindilou50
check the oil filter from the oil tank,the oil line ,the worm gear and the oiler under the clutch.Clean the ways where the oil goes with compresed air.(after you fill out the oil tank)Also check the oil hose.

Replace the oil pump..Or just try to clean it out but I have been through this and it worked for about ten minutes and I ended up just replacing the pump and works fine now. They are not very expensive (35.00-40.00) and only takes about ten minutes. Get a beer and a table or the tail gate of you truck should be fine. Take off the side cover remove the bar and chain. Clean everything up... air compressor is best a paint brush and rag works good if you do not have a air compressor. Take the top plastic cover (three screws on top of the saw). Pull the spark plug and feed a piece of rope into the cylinder. This will bind up saw so you can remove the clutch. I use a pull start rope from my old lawn mower and keep it in my saw box for this reason. This size and kind of rope seems to work best. Now you need to remove the clutch. There is an arrow on the clutch that tells you which way to turn it to get it off. This can sometimes be tricky but don't give up. I'm sure there is a tool for this and I keep saying that I'm going to make something. I use the handle of a good strong pair of pliers and turn the plier with a pair of vice grips. When you see the clutch you'll figure out something to use to loosen it and spin it off. Un-spin the clutch and remove the clutch drum by just sliding it off the spindle. Be careful because there is a bushing with needle bearings. The bearings are in there pretty good and wont just fall out. If you want to replace that you can 14.00 or so. There is also a plastic drive gear for the pump that just lifts out , replace it too 6.00 or so. Take off the metal cover I think it's just one screw. When you remove the cover you may see a lot of saw dust and oil all packed inside. If you have an air compressor just blow it all out. The oil pump is right there and is simply removed with one screw. clean every thing up put the new pump in put everything back together and you should be back in business.

SOURCE: Where is the bar oil adjusted from on husqvarna 345

Turn the Hus 345 chain saw upside down, you may see a little Icon of a oil droplet and a + - arrow by the chain. THe adjustment screw is not pictured in any of the standard user manuals,. but it is a small black slot headed screw over a rectangale metal tab by the chain. I believe if you turn it counter-clockwise, it will give you more oil,, It did for me. If you have the bar off, you can start the saw and see it come out the hole, that would verify your oil pump is working. Make sure the holes on the bar are clean also. running the saw at a fast idle for 1 min should oil the chain well enouth that it starts spraying off the end of the bar when you gun the engine.

If all you say is true and when revved up the saw oozes oil with the bar removed, then I suspect the bar is incompatible with the saw. Has the bar been replaced? The oiler holes in the bar must align with the channel in the saw. Oiler hole placement is part of the reason there are so many different part numbers for bars. The mount is only part of the requirement.
