Dennis,
thanks for the reply - even on a holiday like today!
I did loosen the charge adjusting screw a bit while running and did not see any oil leak...I may try to crank the engine with the plug removed to see if any oil comes out. If nothing comes out, could this indicate there is some internal blockage internally?
I was going to cap off the drive motor after I did the adjustments, as no one seemed to have the M26-1.5 caps or anything can cap it off for short money. I will go this route to see if I can determine where the problem is, as capping off the pump is simpler. Either case it looks like it will be lots of money as drive motor is ~$1800 and hydrostatic pump is a lot more...and neither are readily available.
I just want to make sure I am not doing something stupid and overlooking something. I will go through the procedure a few more times, and really make sure I have the pressure gauges in the right locations...as there are many test ports/plugs on the pump and the pictures in the manuals are not 100% clear.
Another question for you:
You said the pressure when the motor is capped off should be 3600PSI. Where is this measured, on the Charge port or at the output from the pump to the motor...or are they internally connected anyway?
Thanks again for all your help.
