I just pulled the pump are seals hard to change? And I thinking right that that is where its leaking? That was like 15 minutes to do a lot easier than the new stuff! Be back later. Greg

It could be the seals, but more likely that the bearings are sloppy and that ruined the seals. Pump center could be cracked too.

Thanks Brad, I took the three nuts off and one O ring looked compromised. I don't think it will be that easy. Greg
 
Greg,
At this point you should open the pump and measure the shaft to see if they are worn undersize. I have replacement seals on hand and I have rebuilt drive sleeves. I also make new idler shafts. Also when you take it apart, look carefully at the center section to see if it is cracked. Sometimes the crack is hard to see.
 
Centerplate, thanks or the info. When I got home tonight I put the pump back on the housing and set it on some sawhorses to see where it leaks. The centerplate looked ok but seals did leak when I added fluid. Haven't pulled pump apart yet. Do you also have the centerplate if I need it? Had to ask because of your handle. I can feel it wiggle where pto input shaft goes thru the pump so I figure that isn't good! What is the best contact method for you or do you rebuild them? Thanks ,Greg

If that hollow shaft wiggles, your bearings are worn and your shaft may also be beyond specs. I have the center section and anything else you need. 60eight-2 one 43852 I sent an email.
