Nik's Poulan Thread

[Kostas]

First i must say a huge thanks to all of you guys for your responds.Let me say how the things are.I was ordered 4 crank seals(2 to replace and the other 2 just in case) from ereplacementparts.com because they are the only who asking resonable shipping to Greece.Searspartdirect,Poulan.com etc asking 50$ for shipping to Greece if i order a couple of small things such as gaskets,seals etc.Ereplacementparts has not seals anymore because the manufacturer put them on Backorder with no ETA.

Anyway,this morning and after Mark's statement that replacing the seals are cheap insurance,i decided to replace the seals on my saw even if they looked like new from the outside.I must say that i tested the saw on vacuum/presure test and it was holding for joke.The only thing that made me thinking of an air leak was that when the saw warmed up,holding a little rpm's after the WOT and getting to idle after a couple of seconts.Well someone must replaced the seals before me because the clutch side seal lip was punctured with the spring outside of the groove.Really happy that i found it.

Hi guys,
I'm replacing the motor in my 2550t with a complete motor from a pp220. I had a wrist pin come loose on a new piston which took out the piston and the cylinder on the 2550. This rescue is getting expensive. Opps that going to leave a mark!

1. The crankcase cap on the 220 doesn't have the groove in the mating surface that the 2550 had so I'm wondering about the liquid gasket (permartex motoseal) whether it will still work OK. Or should I use the 2550 cap that does have the gasket groove. They have the same part # but are slightly different internally. It may not have the right clearance when everything gets buttoned up.

I've decided to just ask one question at a time. That way I can try to keep my head straight.

many thanks for opinions and help. Love this site, and a couple of others too.

Seems to me it should work okay. Fellas use sealant on their split case saws all the time and there is no groove between the case and cylinder. I would therefore think the same would be true for a clamshell saw.

Thanks for the info Mark. Since both the 4200-8500 Poulans and 288XP Huskys use 6203 bearings (on both sides), I'm thinking that the Husqvarna 503 26 02-05 seals could be used in Poulan 4200-8500 saws so long as the seal body widths are the same (as the housing bore and shaft measurements must be the same for the same bearings to work in both saw families).

That would mean that the National 471466 seals could also be used on the Husqvarnas (again so long as the width is compatible). Might be easier for Kostas to get the Husqvarna seals in his part of the world. Although with the internet, that's not as much of an issue anymore...

Well Aaron i thought something like that but i must say that the 306A also use a 6203 bearing on the flywheel side but the seal is way different(smaller on both OD and ID).

I'm thinking that your way out there with those ideas really.

Now I dont claim to be Swede saw expert but what I do know is that every Swede made Husky or Jonsered that have worked on were all metric saws incuding metric sized crank seals. Like 30x15x6 etc.

The old Poulan saws were inch saws including the seals if you know what I mean.

So I think your reaching there for something that probably wont be happening.

Right, bearing size has no bearing on the the seal sizes.

That happens when someone tries to install that clutch side seal without a seal protector on the crank to guide the seal lips over the step in the crankshaft.

I have posted before how to use a strip of aluminum from a beer or pop can to wrap around the crank before the seal is installed.

A piece of 1/2" copper pipe cut with a tubing cutter and deburred (tube cut end out) also works well, at least it does for the 3400 series.

Hi guys. Did I ever mention I really like this old green saw ??

Have a good day now

Well Mark i was really worried about how should i remove the old seals without damaging the housing bore or the shaft.It was very easy,so easy i couldn't believe it.With a flat screw driver i hit one side of the seal which went deeper in the housing bore and that force the opposite side to come up.Then with a spoon (not from the side we eat,from the side we handle it :msp_biggrin pushed gently the lip arround of the crankshaft.It was super easy.I am really curious on how the saw hold both vacuum/pressure with a seal like that.I must say that i used the saw a couple of times but fortunately without any further problems.

Yeah you're right. Got that hairbrained idea from the last saw that I searched for 'generic' seals for...............a 'unit block' yellow one. Bearing inner and outer dimentions are the same as the housing and shaft dimentions on those saws (same with most 'clamshell' saws).

On saws with seals pressed and bearings in however, the outer diameter of the seal body is whatever the saw manufacturer feels like making it. Only the inner measurement is the same between the seals and the bearings (because they must both match the crank diameter of course). I haven't laid an egg in a while. Was due for one...

4200 test cut

I think I've got the 4200 running pretty well. I had to do three takes to get a video because my camera is not working well so I finally used my wife's. The first cut went pretty well, it's running a bit rich. I had to lean on it a bit to get it 2 stroking. I cut so much off the round trying to get the first two videos that there wasn't much left so the clutch cover was hitting the bucking stand on cuts 2 and 3. Since I have nohing to compare this saw to, let me know if you think it's cutting as it should.
As per expectations, the diiference between the 3700 and the 4200 are more like 15cc apart than 9.
I think this will cut right with or faster than my Homelite VI922 which is 77cc.

83cc of poulan getting ready to go. Using a 066 piston in this one. Used my worst recoil as you can see and homemade 268/272 clutch cover to use on the poulan. Amazing the fun you can have building from extra parts. :hmm3grin2orange:

Cale had a good idea. I should have painted the clutch cover purple like a wild thing. :msp_tongue::msp_thumbup:

What's a Poulan Pro 4218A (vs 4218AV)?

I sort of accidentally bought a new 4218A off the internet the other night (don't ask) and wondered just what it is and if it's any different at all from the currently listed 4218AV? EPA sticker says 2013 compliant and owners manual was printed 8/2012.

Thanks. -WSJ

 

[WSJchester]

No, that's the one - no AVX foolishness. But it's distinctly labeled "4218A" and not "AV" which has me wondering. Oh, and it has a "color matched" bar! Really - it's printed right on the bar. Case, bar oil and PP synthetic oil included.

Well it didnt take you long to lay another egg it seems. :hmm3grin2orange:

Not all seal inner dia have to match the crank dia at the brg. There are some that can have a step on the crank (can't remember exactly which one I seen that on) while others can have the seal inner rideing on a sleeve over the crank, a Poulan 361 comes to mind on that example.

 

[WSJchester]

Interesting. I don't know much about these things, but I do know that you can buy a Poulan that is called a 34cc saw and you actually get a 42cc saw. They run pretty healthy for only 34cc's:hmm3grin2orange:

Yeah, heard about that. But this one is EPA labeled 42cc so I expect that's what it is.

You ain't right, but I like it......the saw that is......that starter cover will make it easy to check the timing on that saw.

Nice sign, seems I have seen that one before. Is that the same one that was at the Poulan GTG last fall? Looks identical.

 

[WSJchester]

yes many of them are...even when they say something else on the marketing decal on the recoil...

I need to put the 34/14 decal on my 8500 recoil when I have the 15inch Pro Champ bar on it and let my friends use it and see if they think it runs better than thier little huskies...yes I know it is heavy for a 34cc saw but it is 30 years old,,,,but it runs goon don't it?

Well maybe you ought to take those massive dawgs off it first . . . :msp_tongue:
