We installed a new R6 rototilt on a 2005 hitachi zaxis 200lc. It now has alot less hydraulic power for all the functions and the power boost doesn't work anymore. We removed an old thumb setup and solenoids. The aux pressure was increased for the rototilt. We did cap a port on the aux solenoid spool on the right side of the main valve block that was plumbed in for the thumb controls.. I will post a pic of it asap. I have hydraulic and electrical schematics , but can't id the aux spool ports. If anyone know these machines please help. Thanks
