Komatsu PW 110R-1 auxilary oil flow stopped working

KRMOTO ยท 2021-09-01 05:24

Hi guys, my PW has breaker and grab options with a manual valve lever for single or 2 way oil flow, this was working fine using the buttons for a rotating timber grab 12 months ago, since then had a digging bucket on, just put grab back on and no go on buttons, with inition on can hear the solenoids clicking on both buttons, with engine running can feel more of a thud in the cab when press buttons, would be very grateful for any pointers, cheers.
