[QUOTE="Tazza, post: 99318, member: 82"] Ok, so i have been lazy for the last 10 or so years. I got a machine that had a small engine bay fire and the pump/engine were removed by the previous owner. FINALLY the day/week/months have come to actually get it going again. Sadly i didn't take as many pictures of current progress as i should have. I had the chain case hung up by my S250 so i could blas it with a pressure washer. The tag line was going to be, how do you wash your skid steer? but sadly the picture was not taken, oh well. Back to the build, as the engine/pump was was out when i got it, the pump ports were not plugged up. I didn't notice this till it was home and i could see brown fuzz inside the fittings, after opening it up, the rotating groups were toast. I have pictures of the pump that i will dig out too.
