I am resealing the front hydraulic pump on a 3020. The new quad seal is really loose if placed over the shaft. But it seems to be the same size as the old one. The shaft shows no wear. It does not seem to me that the seal would get compressed when installed, and I am trying to imagine how it could work if this the the correct one. Also, is there supposed to be a small step-like lip on the face of output valves? Thanks for any help.
 
Thank you. I have learned a lot from you guys. Last year I overhauled the engine in my 2010. This year we are restoring a 3020 gas. The info is very helpful and much appreciated.
