Yep that is the one I put in.    We will see how it holds up, but I would not consider the crank case pressure to be high.

Sounds like same seal but half the total price shipping etc?  http://www.ebay.com/itm/Oil-Shaft-Seal-15-x-35-x-5mm-Price-for-1-pc-/201247726172?pt=LH_DefaultDomain_0&hash=item2edb4c9a5c

I am surprised that the pressure rating is only 7 PSI.

Thats why I am wondering about crankcase pressure running and cutting. Dont people test with mini vac to 10?

The test pressure is 1/2 atmosphere

Which is 7 lbs pressure soap bubbles for leaks

or

15" vacuum to double check seals 15" intial vacuum - wait 30 sec and there should be 10" vacuum left or the seals are bad.

I was going to check the squish on my 3500 before I take the cylinder off and I cannot find my solder.   I will be so glad when everything is organized again and put back where it belongs.
