SOOO, with the monsoon rains subsiding, I finally got to get under the bus to look at the pump "weep".

Observations:
- It truly is a weep, no noticeable loss of fluid, still at the same tank level
- The cavity is empty and stays empty??? Huh!!! How do I know that, well there is an inspection "port" / line hole not used in the back of the PTO flange you must put a plug in. I removed the plug, used a dental mirror and high powered flashlight. I can see all the way into the cavity and the shaft splines not in the pump, cavity is dry
- The weep oozes out between the PTO Flange and Pump, where it bolts up.

I will FIX this when I get home in the fall as the next walk about will be a very long one.

Questions:
Does the wet spline conversion have a different PTO flange from the grease version? to better seal the PTO and Pump cavity???????

If you convert to wet spline and the pump seal eventually lets go as other owners plus myself reported, are you now mixing hydraulic fluid and pumping it into the transmission as David suggested????

I am not berating anyone's decisions on how to upgrade the PTO/Pump...We are all adults and in the end we call our own ball and live with our decisions. I just want to report what I see going on in my new grease setup.......... new pump AND new PTO
FWIW my 18 year old no grease, no wet setup NEVER leaked a drop of either fluid and the splines would have lasted another 3-4 years...They sure don't SPEC and make things like they used to!!!!!

Pete,

When switching from a greasable PTO to a wet spline; what happens to the grease in the PTO? It gets mixed with the transmission fluid;doesn't it? I doubt that it is enough to hurt anything but it may be prudent to flush out the grease by removing the end cap (the one with the grease fitting) for access. Also the grease fitting should be removed and the hole plugged or replace with a new end cap with no holes.
