If that suction system is not air tight, you will not get proper charge pressure. (Very important) And if charge pressure is not within recommended specs… Full stop!!!!! Don’t even look at hst high pressure.
For whatever this is worth, maybe it will help someone in the future. The 25 psi charge pressure was resolved, now I have 95. I took the darn hst apart 3 times All it was is the 2 o-rings that are on the suction tube assembly.
Thanks for quick reply. Are you referring to the charge relief valve having debris? And when you’re talking hst relief poppett Is that for the high pressure?
Hi Aurthuritis.. I have a 2007 Kubota 900 RTV...The assist motor housing broke, (had been cracked for a while) and I lost all the oil...I was moving along 5 mph when it happened and I shut it down right away... I replaced casing with a new one, replaced both filters and fluid with all Kubota...
