Poulan pro 44cc 20" chain saw - chain oil not feeding
willshak
oil is not oiling the bar and chain. I took the cover off the bar and
chain adjustment compartment, took the bar and chain off, cleaned the
whole compartment out, and looked all over for a clogged feed line or
something, and couldn't find where the bar oil was supposed to come out
to lubricate the chain. I think the oil may come out onto the drive gear
under the centrifugal clutch.
The saw is full of regular bar oil. Unfortunately, I can't find the
manual either. Any ideas, or a web location where I can find out what's
wrong?

Check the oil holes on the bar itself. That's what I have to clean most
often on my (non-poulan) saw.

I'd be surprised if the manual isn't available at www.poulan.com

Oil pump failed in my Poulan Wild Thing and was repaired under warranty.
Plastic gears stripped or something like that. I think it is a common
failure. Wild Thing is not a professional model but others may not be
all that different. Authorized dealer was out in the boonies and I
should have just tried to take back to HD where I bought it.

Thanks, but there are no holes on the bar, other than the holes the bar
adjusting rod goes into.

I found my manual after I posted the message. Under Bar Maintenance, the
manual says 'Clean the oil holes after each 5 hours of operation', but
doesn't say where the oil holes are, or how to clean them if you could
find them. The manual doesn't have an illustrated parts list either.
The manual on line is the same as the one I have.

Thanks. I have had this saw for 8 years so there is no warranty.
I think it might be the oil pump that failed. Unfortunately, I messed up
the chain, bar, and sprocket when the oil stopped flowing. I was too
busy looking at the saw in the cut and didn't notice right away that the
tip started smoking and the chain guide teeth turned red going around
the tip of the bar, when the saw just seized up. It chewed up the teeth
on the drive sprocket, and the guide wheel on the bar tip. The chain
tooth guides probably got so hot they lost their temper (as did I!).
I'm looking at about $100 in replacement parts; pump, chain, bar, and
sprocket kit. The saw costs around $200 new.

On an old Norelco saw I had from years ago, the chain lube went from the saw
body into the bar near the drive sprocket, then existed through holes in the
chain track on the bar. Don't know if Poulan uses a similar setup though.
Used a piece of stiff wire to clean the holes. Used to test the oiler by gunning
the saw near some clean wood or newspaper. If I saw oil spray, I knew it was
working.

Thanks.
Like I told another, there are only two holes in the bar and they are
both for the adjusting screw to extend the bar to tighten the chain.
There is a small hole on either side of the tightening bolts slot for
the single adjusting rod, and thats because the bar can be mounted
either side up. There is a worm pump under the sprocket/clutch and
that's probably what failed. Apparently the worm gear pushes the oil up
through the sprocket assembly which then transfers the oil to the
sprocket, chain and bar when the clutch is engaged.. What is unusual
about the chain oil operation on this machine was that when storing the
saw over the past years, I had to put a large disposable aluminum baking
pan underneath because the oil dripped out and made a mess on the shelf.

The first thing went out on my Poulan Pro was the oil pump, so I went with a
Husqvarna but it lasted only 5 hours before the engine died and Husqvarna
won't fix it under warrantee. Funny Husqvarna suppose to be the industrial
version of the Poulan Pro. Anyway I'm looking at a Milwaukee electric
chainsaw and have the old Poulan Pro as a backup when electricity is not
available. I usually test the oil pump, it draws a line of oil when the
engine is speed up. before I do any cutting. BTW, 18" electric Poulan Pro
under $100 at Amazon.com.

I know this is an old post, but maybe you're still there or others will benefit:
I have the Poulan Pro PP4620av model, but many others are similar.
On the Poulans of this same type, the bar adjusting hole on the bottom engages with the bar adjuster pin, but the top hole is open & used for the Bar & Chain oil to flow into the bar under pressure.
When you flip the bar to even out the wear, the top hold will be the oil hole.
To test if your saw oil pump is working, remove bar & chain, leave side cover off & run saw, let idle & rev up. Leave on for a couple of minutes - you should observe bar oil flowing from the upper groove / slot in the upper portion of the 'bar plate' - [(the metal plate held in place by the two bar bolts (studs, actually)] if the bar were installed, this would flow into the bar to lube things up.
The oil should be flowing readily down this plate & pooling as saw engine idles & flow increasing with engine speed.
If your saw flows the bar oil, then your bar groove likely has a build up of saw dust & chips that are blocking oil flow.
Take a thin piece of metal, thin screwdriver or even the end of a medium zip tie, and run down the bar groove from tip to the rear end - you will be amazed at how much organic wood material & oil gunk comes out !
This should restore the oil flow to the bar & chain.
I make a practice of 'aiming' the saw bar at a piece of wood, etc, and revving up strongly to check & see if oil is flung off the tip & makes a stripe of residue, confirming bar is being oiled. I'll do this every 2-3 long cuts.
The only other helpful hint I have is if it's cold winter weather, thin out that Bar Oil with some ATF.
I find 22 oz of Bar Oil (Huskvarna brand) to 10 oz of ATF (Quart total) to be a great mixture, when the temps are averaging 50 degrees & lower. The thick oil just doesn't flow well at those temps & the bar & chain starve for oil.
It's also got to be easier on the oil pump to not try to pump the thick syrup like Bar Oil at low temps.
I've learned all this by servicing my Poulan Saw. It's going great after 3 seasons & probably 40 hours of runtime.
