[QUOTE="palmtree, post: 82178, member: 10256"] I'm the guy that has posted several times lately. The boom hydraulics were working fine when i bought the machine. The drive was not good. Really jerky, lack of power (especially with turning), hydro light would flicker on and then stay on. I was told that the pumps and motors were worn out. So I had both drive pumps and both drive motors rebuilt. Got everything back together then the charge pressure light didn't work. It was just a loose connection. Fixed that and then I followed the service manual for initial start up after hydrostat overhaul. Drained lines, cooler, cylinders. Cleaned chain cases. I cranked the engine without fuel a few times till the charge light went out (It turned off really quickly). then I ran the engine at half throttle for 25 minutes on jack stands, then stoked the levers for 30 seconds to bleed the air from the motors. All seemed fine. Charge light stayed off the whole time. It was late so I left it on the jack stands until this morning. This morning I brought it down to the floor. Fired it up (charge light went out after just a second or two). Pulled it out of the garage and it was kinda jerky. Seemed to get a little better as I drove it around for a couple minutes. Then it got much worse. Basically the same as it was before the rebuild. Boom/bucket works fine. Drive is jumpy, not smooth and turning is not good at all. Then while turning around the charge light started flickering then came on. I shut it down right there in the middle of the driveway (I still need to move it but though I would ask for any help first). Where should I even start? Seriously my wife is going to kill me. I can't keep spending money like this. I already spent $3000 on the hydrostat rebuild. What else is there? Thanks for any help. [/QUOTE]
