Post subject:  lose of hydraulic pressure on T900

machine number T9062
serial number C75570
hmr 56.3
This is Eric Myers from ISCO in martinsburg wv. I have this machine that we just replaced the hydraulic pump under warranty.
The problem is that after machine warms up we lose hydraulic pressure to entire machine and carriage.
start up pressure is 2300 psi
after 30 to 45 mins system pressure will drop to 300 psi.
have switched out hydraulic fan motors still have issue.
removed carriage from system and still have issue.
Can some one please give me some information if the replacement pump is defective or if I have a problem in the system past the pump, maybe relief valve or bypass valve.

thanks

Give us a call when you get a second. I am also suspicious of the diverter valve.

Was there a resolution to this problem? Curious minds want to know. :|
