- 2007 Kioti DK40se HST, Woods BH
Note: during Kioti visit the engineer did mention the possibility of replacing the pre-charge hard line between the cooler and the filter to further boost the pressure to the HST. My understanding from Kioti is the pressure at the HST in-port for my tractor is within specification, but since I don稚 have a pressure gauge I can稚 verify it. Since the in-port pressure was within specification Kioti didn't feel this pre-charge line needed replacing.
I am no engineer but am wondering if measuring the hydraulic pressure at the in port (or elsewhere) when the HST is not actually working (ie in the shop on a lift) might give a normal value because the pressure will be measured in a static state. If there is a restriction that would not affect pressure distal to the restriction unless there was also flow. Does it make sense that pressure might drop as flow increases?
