Hi, How did you make out with this. I have one too running well accept for the swing - ha ha. I'm working on it. Hydraulic motor is ok but teeth are shredded so I pulled it apart to replace the pinion gear. Would like to hear where in the world you found your part if you don't mind sharing...I picked up a scat trak 520v thats been passed from a few owners due to parts available. I got it home after i made sure it ran and had hydraulic pressure. The swing motor and boom cylinder were missing. After a 6month wait i finally got a swing motor from italy. I havent installed it yet because i need to track down another fitting for it. I have all the lines capped off. It tracks and steers, and the dozer blade works flawlessly, however i have no working cylinders on the boom. I pulled the lines off while its running and its getting hydraulic fluid without engaging the joysticks. Do they work as shut offs? So killing flow in either direction lets them operate?
I finally figured it all out. Im now a pro at this machine haha. I ended up just chasing the harness around and double checking everything. Ended up being a tempermental relay. Got a few bugs to work out but other then that im good to go. Parts are hard, italy and australia. The swing motor i waited 8 months from italy. It was brutal. I just found another machine that I bought and will be parting out. There was a few pieces i was needing which basically left this machine unusable. Let me know what parts your looking for and when i strip the machine down ill send you prices and pictures. Im located 20mins north of New York CityHi, How did you make out with this.
