Hitachi Seiki hT20 frozen hydraulic chuck actuator bearing???
Hey guys, was running my HT20 and loud bang and hydraulic fluid everywhere!!! It appears the bearing in the spindle chuck actuator froze up and spun the actuator and ripped off the 2 hydraulic lines. Does anyone have any experience with this? Got everything cleaned up, but have not taken the hydraulic chuck actuator off of the machine yet. Hoping for some more information or experience with this. The spindle spins just fine, just now the spindle and actuator spin together.
thanks for any information
