Yes you have to raise the loader frame up about 4" to clear the crossbeam,remove the three bolts on each side where the loader is bolted to the crossbeam,also remove the two bolts either side from the bracket on the track frame to the loader frame in front of the sprockets and then jack up the front and put a 4" block in either side between the crossbeam and frame,the pipes going into the cooler will pull out when the clamps are removed,I used to have a custom made piece of T bar for removing the engine,there is threaded holes in the cylinder head for fitting a lifting bar,as far as I remember it is important when fitting the engine to have it at the correct angle so the sealing rings on the torque don't get broken.
