if it were me i'd release the engine lift it and swap clutches over
i love working on ohv lumps cos they are so small and you can pull them out in under an hour, i wouldnt bother going underneith when its so easy from above
remove all hoses and wired and then th ebolts and lift it up, if you dont have a crane more hassle i know, we used to lift them out 1 on each turret

i also have fookin gearboxes and all the other fragile crap that will go tits up while you are doing it like cv's ball joints and bushes
