Help a rookie out

[Terrence Jefferson]

Ok so I'm rite in the middle of building a Husqvarna 570 and I made a big mistake. I had a 570 and a 576xpg tore apart and I am rebuilding the 570. I have the lower end all together and piston and jug on and it's all glued and gasketed. I went to pressure and vacuum test it tonight and I can just hear air.... I'm not happy with this so I get to looking it over and decide it's my block off for the muffler. Replaced all of that with a new block off plate and still hear air and can't put any pressure in it. So as I'm pumping and looking it all over I see the crank seal on the fly wheel side looks like it doesn't fit the shaft. So I measured it and sure enough the seal is too big for the shaft. I removed the seal that doesn't work and try the other one on the crank for the 576xpg and it fits cause the crank is stepped up where the seal rides. I looked for a seal number and it's no where near the number I got so now I'm not sure I used the rite crank. I did have all the parts separate so I think it's rite but I need to know what seal to use for the shaft that measures .591 inches. Any help would be greatly appreciated so I don't tear this thing down and start all over. Thank you.

Oops. At lest you didn't forget the case gasket. LOL What are the years of the saws? You should be able to sort it out here if you have that info. I think there was a stretch where they used the same crank anyway. May be wrong about that, tho.

Thank you for the help. I went to the local dealer and he gave me the wrong gaskets to begin with. So with any luck I'll have it running tonight.
