[QUOTE="anitel, post: 3344, member: 535"] It's really quite easy to pull these sideways mounted engines. Just disconnect the hose and steering linkages going into the main pump under the cab. You will need two large wrenches and lots of patience to do this but it is the best way. When you put the hoses back on later use new O-rings from bobcat dealer or suitable substitute. Then disconnect engine wiring harness from back of the under side of cab near hyd tank (oh yeah, drain hyd tank). Then drain coolant lines and disconnect them. Disconnect battery, remove coolant holding tank and bracket, disconnect exhaust and remove muffler. Then you have four bolts at the four corners of the engine and pump sub-frame. Remove those bolts (3/4" drive) and the engine will lift out from the rear with the pump still attached. This is the bobcat approved way and written up in the service manual. I can pull one out in about 4-5 hours with the pump hoses being the biggest pain. Installation is easier once you get the engine back in and lined up. Bobcat suggests building a engine pulling frame but I just use one of the forks of a forklift and a very short chain. The v2203 has two loops for lifting on it, one is near the breather and the other is near the intake opening. Don't worry, just take your time and label your hoses for reinstallation later.
