I have a sk 70 kobelco that the bucket and arm will run start moving then slow down halfway or stop through the stroke and the takeoff again. I pulled the hoses off the cylinders and no matter which way you work the joystick fluid flow through hose. seem to me that the cylinders would deadhead. any help would be great. thanks shane
What are your tracks doing? If track is also poor common fault with sk70 -1 is pivot for swash plate wearing groove in back of swash plate. Also carry out case drain test on Hyd pump
