i picked up what i think is a 610 a while ago. it was pretty well stripped. so here is what i did. I repowered it with a 4 cylinder water cooled Kohler L654 from a generator. but i haven't found a way to put a hydraulic pump on the motor yet. plus all the hydraulics were missing from the machine like the pump, all lines. all valves, levers, rods, even the peddles were missing . so i bought 2 electric/hydraulic power units and mounted them on the back. works amazingly well. any way to post pictures of it in here ?
