Urgent: The hydraulic pump is working well, it lifts the blade but will not push it back down. Have tried 2 different rams. Rams are ok. Pump will push oil out the hose at good rate but when reconnected to the ram/blade it seems to jam. Have dismantled control valve, no broken or damaged parts and no foreign obstructions. One O-ring on control shaft(diverter shaft) seems to be too narrow for the size of the recess. We're stumped! Please reply, Pete.

Have you checked the pressure relief valve?, this can cause similar problems with attachments.

Also check auxilary hydraulic lever is working properly sometimes they can be obstructed and jump shut under laod
