[QUOTE="skidsteer.ca, post: 53549, member: 307"] I have a customers 328 here for some work, has @ 2800 hours, needs some pin work and tlc, but I'm more concerned about something he never really wanted fixed, but after discussing with him its clear it needs it. The hydraulic jerk on all joystick function, and the oil in the res gets foam in a heart beat after start up. I can't see any leaks in the suction side of the system and it should leak as the pump is below the fluid lever. How common is it for the sear around the pump shaft to fail, is it usually a seal only or time for a new pump? I have yet to dig into the manual, just wondering if anyone has any thoughts on this.
