Question about Poulan Pro Chain Saw 46cc 20"

1 Answer

Poulan Pro 42/18 gas Chain saw: The chain oil hole that feeds the upper slot seems to be blocked. Does that rubber assembly just pull out or does the whole area have to be taken apart. Is it gravity feed or is there a pump in there somewhere. Thanks GS

GS, there is a pump driven by the clutch sprocket/drum. Operate the engine with the bar off. There should be oil coming out.

a) If so, the hole in the bar is plugged with saw dust. This is very common on all brands of saws.

b) If not, then remove the clutch/drum assembly and inspect the worm gear drive of the pump.
*note, the threads on all chain saw clutches are Left Hand reverse threads.

Why won't the oil feed to the bar and chain

Good morning Jeremy.

I have a couple of thoughts, and pardon me if any of them might seem way too obvious. Most of them are based on my own wide range of trying to figure out why my old McCulloch wasn't working :-)
  1. Is there oil in the bar/chain oil reservoir? This is the easiest one to fix, fortunately, by adding oil.
  2. Is the oil outlet to the chain/bar clogged? Will likely require some disassembly to get there. The rear gear/drive area is a natural spot for wood chips and sawdust to clump together, bound with a bit of chain oil. With enough build-up, you'll get both more drag on the drivetrain, and possibly reduced or impeded oil flow. I seem to recall there being a couple of through-holes on my McCulloch where the oil feeds in from the side, and they have been clogged solid at times. This would likely be addressed by removing the chain and blade and giving them, and the junction area, a thorough cleaning. (Remember to properly tension the chain when you re-assemble)
  3. There is an oil pump listed amongst the replacement parts for the saw on the manufacturers site It's possible that the oil pump has failed, or the oil pick-up is clogged or disconnected, in which case there will be no oil flow. See items 49-53 in the exploded part diagram.
Those are my primary thoughts. You can also see a soft copy of the manual here Poulan Pro 115327926 Instruction Manual Page 16 to look at other tips on running the saw.

I hope this helps!

My saw simply will not pump chain oil. Iv'e run it with the bar and chain off and the pump works.Put it back together and nothing. Before reinstalling the bar I blew the saw clean. I had a Sears Poulin a...

Check that the bar oil ports are clean; there should be a small hole or slot on each side of the bar and these can become pluged with sawdust. Also clean the groove in the bar with a small screwdriver or bar cleaning tool every 8 hrs of operation.

If this does not fix the problem check the oil sump screen in the oil tank(usually on the end of a rubber hose); if no screen in tank: remove oil pump and clean(screen is sometimes in oil pump assembly).

Brand new poulan pro 4620avx--bar oil is coming out of oiler but not getting onto chain

Hello. Thin your bar oil just a wee bit with some kerosene. If you have a gallon of bar oil add 1/4 cup of kerosene, stir it up and you will be fine. For starters also, directly apply some bar oil to the chain so that you are always using a well lubed chain. Joe

Same problem here, only with an old 305.

Remove the bar and chain and clean the port where the oil comes out of the engine. Clean the holes at the back of the bar on both sides including the small ports that pass oil into the chain slot. Blow them out with compressed air if possible. Clean the chain slot and oil the tip sprocket if it has one. Make sure the mounting faces of the bar are clean and smooth finish.

Poulan oiler don't work

Common problem with Poulan and Craftsman gas saws. Take off the chain and chain guide and clean out all the saw dust etc. Start saw without chain and look for port where there are signs of oil. If port is clear of sawdust, then it is likely the pump which is located behind the chain break assembly. you can get the diagram on Poulan website and the replacement pump will cost about $15 - $20 to replace yours.

I have a poulan-pro 20" chain saw ... It doesn't seem to have good chain lubrication ... How do I check if the chain oil pump is working (or if there is a clog) ... The manual is poor ... Thanks ...

What I would do is remove the bar and chain. In the side of the bar are a couple holes that feed oil from the saw into the bar grooves. Make sure these are clean of any debris. Then look at the side of the saw where there is usually a wear plate and make sure the groove there is also free of debris. Lastly I would start the saw WITHOUT the bar and chain and look for oil coming from the groove area described above. If nothing coming out then you have a problem with saw motor and would have to go deeper into it.
