I am replacing the seals in Hydro pump...HELP PLEASE!!

I am going to replace the "Housing O-Ring" in my Turf Tracer HP hydro pump because that is where it is leaking from. My question is, do I need to take the whole pump off the mower, or can I leave the pump on the mower and replace the O-Ring with the pump still on the mower?

Any helps, tips, or advice would be greatly appreciated!







Here is a link and the O-Ring I am talking about is schematic number 10

Well you've got balls for sure! This isn't for the faint of heart!
Take it OUT!! This has to be CLEAN CLEAN AND CLEANER!!
BUY THE WHOLE SEAL KIT!! Don't try to save a buck, not on this and not for $20!! Buy a tube of white lithium grease and use it to lube the seals.

OK, it looks like if you put it with housing 6 on the bottom, the drive shaft down, then you wont have to mess with the "cylinder block set". It's a georoller and you don't want to mess with it anymore than you can! Sub group 46, really bad if it get dirty, really bad if you get the pistons in the wrong holes (yes they are all the same but they wear differently). Sub group 23 appears to be a gear pump to charge the georoller and swash plate assy. That is where I would start with disassembly. If you are lucky (and it LOOKS like you would be) it wont have to be "clocked" for timing, then remove bolts 19 and 20 and remove cap sub group 16 off the housing.
Now I know you are curious, I know it all looks cool inside and we all want to see it. BUT LEAVE IT ALONE!! DO NOT MESS WITH THE GEOROLLER ASSY!!!
Lube the seal and put it back together!
Now I do not recommend this without some knowledgeable help there, it's not hard, but there are a lot of little parts, and a lot of ways it can go wrong! Keep it as clean as you can and change out as many of the seals as you feel you can safely get out. "Once one goes, they all tend to follow!"
And keep it clean!

Now you hurt my feelings. I was just asking a legitimate question. Maybe there are pumps out there with multiple swash plates and georollers assy's.
