If you knew the size of the seal, you could get one at the local bearing supply business?

Seal pocket size?
Crankshaft size?

sold out now but a member had them.  http://www.sawagain.com/jonsered-450-455-510-520-525-535-crankshaft-seal-504146204/

Looking at that seal a drywall screw and pliers to pull screw redneck method would work.

thanks for all but what is the redneck method?
do I have to drill and screw the drywall screw into the seal and use pliers to remove it pulling the screw?

I use small now to poke hole screw in drywall screw and then jerk out with pliers. Can be tough at times and need to pull several times, some do pop right out. Some times might need to make 2nd hole. 

Yep all above equals Redneck Method IMO.

so I'm looking for seal 35x15x7... any idea to find one similar...
Title: Re: CRANKSHAFT SEAL 504146204
Post by: 660magnum on February 11, 2014, 06:41:57 am
You are looking for a seal 15 X 35 X 7.  This is a companion seal that goes along with 6202 bearing applications

Using these three numbers you should be able to find a seal supplier in France or where ever you are located?

Here's USA Ebay

The Nitril will be fine and is what the original seal was. Viton will work too but generally costs more.

The original seal was a single lip but you can use a two lip if you want as it would be better.

You could try warming up the area with a electric heat gun?

If you have a big soldering iron you could try warming up the bolt head with the soldering iron.

Well you could call it big I suppose .FWIW I have two American Beauty irons,vintage .One is 400 watts one is 750 .The big one I can solder a radiator tank with .The copper tip is an inch and a quarter by two inches long .It will melt bar solder like it's butter .

Yeow! Al, my wife makes leaded glass windows and the biggest iron she uses is 150 watt. I have never seen a 400W iron let alone a 750 watt! Good on ya!

They still make them ,Mac Master -Carr is one place that sells them .I got those things at an estate sale for next to nothing .It takes twenty minutes before they heat up .

The largest "pistol" type I have is a 200 watt Weller .Takes it about 5 seconds .

i finally find one in a moto shop in Italy! it was the last of a new old stock!

for the iron 100w is big when you sold electronic parts, but if you re a plumber it s small... in France we use big solder to do the waterproof of the top of the houses.
