I ended up not having to split 475 or 505 in the end. My bearings in the 475 that was feeling rough cleaned up after flushing them out.

The 425 I have split I was able to keep case gasket as 1 piece and will re-use it.

The 415/475 on feebay for $109 plus shipping. I wasnt interested after talking to seller in emails.

Well I got the 475 all tore down.   Cranks bearings showed signs of rust.  The crank case showed some signs of mag rot where the bearing press in.   I had to drill the heads off of 5 of the case screws to get it apart.  Someone had rounded them out.   I have the crankcase gasket and clutch side seal on order.  The piston was scored on both sides and so I am going to replace it with a meteor.   So we will see how it all goes back together.

PP 505, 475, 445.

Alright so I removed the seal and took some measurments.

Shaft           .688
OD.             1.375
Width max.  .250

found SKF 6814.   Looks like it might work.  I ordered one should have it in a week.   

When I removed the seal the bearing looked very dry no oil at all from what I can see.

What happen with this idea?  To wide depth wise?  http://www.rocketseals.com/catalog/o-rings-and-seals-for-u-s-measurements/oil-seals-cr-skf-speedi-sleeves/oil-seals-cr-skf/rotary-shaft-oil-seals-cr-skf%3B7330

  barneyrb = Guys I went back today and there are no more seals for the PP475. The owner of this shop told me that the new bearing/seal assembly (505) will replace the separate seal and bearing without any problem. He convinced me enough to where I went ahead and bought the assembly to replace what I had.

He also told me the reason for the change is this, Jonsered/Poulan had a problem with the separate s/b spinning in the case thereby trashing the case. The JRed fix was to replace the that assembly with a bearing with built in (replaceable) seal and it had a wider outer contact patch with the case and stopping the bearing spinning in the case.

I am building a 415 and using a 505 setup and will report back my findings.

I screwed up Kevin on the measurement.   The shaft is actually .588.   I had already ordered one of the others and did not realize the mistake until it came in and I put it on the shaft.   So I started looking again and cannot find a seal with that shaft size.  I also took metric measurements and it is. 
shaft  15mm
OD.    35mm
width  6mm.
I did find a single lip seal that was close to that but it is out of stock until march.  So I am thinking that it is probably NLA also.   But if I have to do some kind of improvising I will to get this thing working again.  I have the case gasket on order and everything is in place except that seal.  Too much time and money to quit now.
PP 505, 475, 445.

Yeah I just seen this post. Thought hmmm 2 different specs.


Quote from: 3000 FPS;4103252
I am working on a 475 and have been trying to find the clutch side seal.   I was told that it is NLA and have tried several places with no success.    I also tried to find a replacement seal with no success.   Have any of you, who have worked on these particular saws, ever find a replacement seal?   The Poulan part number  503422201.  I believe the 505 uses a different seal on the clutch side.  I could sure use the help.   If I cannot find the seal I guess I will start improvising.
The dimensions
Shaft   .588
OD.     1.370
Width   .250

If a seal can be found with the correct shaft and OD.  the width could be modified easily.

Everything I tried in the metric size came back NLA.
