Anyone have an idea where the oiler breather is? Reason I ask is saw keeps putting out oil after saw is off. Quite a bit at that. Even with oiler adjuster closed is still leaks oil. Oil just keeps oozing out of outlet hole. Wondering if breather is plugged and not allowing pressure to release. I see there is a black crankcase plug near the outlet but don't know if its a breather or not. Bob

I would like to know that also, Bob. My PP380 does the same thing. The thing oils great, with the adj. oiler. But it likes to puke oil out when just sitting also. Other than that, I really like that saw.

Hopefully someone knows. Maybe its just a weakness we have to live with. Wonder if there is any pressure in oil tank seeing as how pump doesn't operate by impulse action?
Bob
 
Have you tried 'burping' the pressure from the oil tank by unscrewing the fill cap after shutting it down?

Thats a thought! I never tried it. But, this fall, just before our GTG we had, I filled several saws with fuel & oil, including the 380, that I thought i would use, but didn't. Saws just sat in the back of the truck, without being run at all. It dumped a good amount in the bed of the truck. And was never started. So it hadn't built pressure from that. Beats me...LOL

Gregg, I did remove the oil cap and put it back on and the leak stopped. That will work, but I and I'm sure you, would like to know what is plugged, thereby not letting pressure release on its own.

a couple of my poulan models just leak after shutdown... some kind of feature rather than a defect, I'm sure...! I gutted and replaced everything (hoses, check valves) on my small 2300CVA -- same feature-full puddle after use. Venting the chain oil cap works for me. I'd love to hear about a 'real' fix, but I don't have my hopes up.

Gregg,

--as nice as the old poulans are, they didn't suspend the law of gravity. If you have a tank of something with an outlet, and the outlet is open somehow, even a little, and it is filled with a liquid, chances are pretty good it will drain until the outlet is above the level of the liquid in the tank.

Just a guess

Gregg,

It built pressure from setting in the sun, or the fact it was warmer than when you filled it. Seen more than one saw flooded out this way. I had the 3450, and used the Aaron method of a plastic wrapped box from water bottles to confine the slick. If there is an oil tank vent, I forgot where it was.

There isn't a vent.
Those saws oil from a pressurized system and are therefore not vented.
If you leave them with oil in the tank every time the temp changes, just like your sealed gas can they will expand and contract, albeit to a lesser degree.
Each time they expand and contract they will "pump" out a bit of oil until the reservoir is dry.
The greater the temperature change the more oil will be expelled.

went thru some of gramps old dealer stuff today.......

Hi All,

Took the 4200, and 8500, rained too hard. worked on splitter cylinder instead. We had a fire going in the saw room, it was great.
(see previous post). I leafed thru some of the Poulan info.......

I found a 3 ring binder with color advertisement for the full poulan line. I think you guys will probably have the most interest in that.
grampa has it dated 1985, but It looks to be older stuff than that. I think it might be from the 1st year of the 3400. here is what it
covers (as best as I can remember). The pages are as new, glossy & flat.

Micro's/25's
3400/3700
42,52, & 6000
woodsplitters
water pumps
alternators
string trimmers
construction saws

I also found a type-writer print "sales aid" from 1979
It compares all the manufacturers saws, in a price bracket format.

It also appears we have a full set of service manuals for saws, trimmers, generators

I didn't get thru everything.

oh, and we have a 25 that dad says is an "alden" saw.......its orange.
Dad said that saw was what sparked the dealer idea.

That's really cool that your grampa saved all that stuff. Certainly will be appreciated by all here I'm sure!!
 
I know Mark and I will be drooling!!!
Gotta see...gotta see!!!LOL


Mike

Darn right I am always excited to hear of finds of documentation like this. I'm still glad that Bo Lowe went through the trouble of shipping that bunch of stuff he had to me to examine and copy before I sent it back to him. Were all still passing that stuff around and its a gold mine to us collectors and saw buffs.

I'm also surprised to hear of the find of another Aldens branded 25. I only have seen one other and its in my shop!
 
Further 4000 exploration

I started digging into the 4000 a bit more with the removal of the clutch cover and the muffler. Here is what I found................

Sure looks like the PO didn't have much run time on this saw and I'm thinkin' this cover had not been removed before;

Everyone needs a home and when something sits idle long enough..........this is what I found when removing the muffler.

I've since rinsed out the loose stuff with WD40..........is it safe to presume that when it gets fired up that any/other looose "stuff" that might be in the crankcase will get evacuated out with the flow of air/mix ??

Mike are you referring to the 3450 when you state its a pressurized oil sytem? Is this a result of the oil pump being gear driven and not operate by impulse air? I guess then the only way to remove the pressure is to take off the oil cap.
Bob
 
Great pics of the 4000 XPLRN. I would agree that it wasn't used much. I see it still has the Poulan branded chain on it also. I think once you get it all cleaned up and gone over, its gonna be like a new saw!:msp_thumbup:
The 4000 is my favorite saw. I know everybody here must get sick of me saying it, but its true! LOL

Has to be a vent, Mike; there's a pump. Without out a vent the pump would only work so long before the vacuum would be too great to allow oil out. Then they wouldn't leak at all.

No. HeRoze brought up the pressurised tank of the micros to muddy up the waters some but the 3450 is a completly different gear driven setup.

There is vent on that system and the micro system as well.

Most people dont realise how well most of the poulans oil and alot of times just residule oil running of the bar tail gets mistaken for a leak.
