Just a matter of removing everything that's connected really, i do it in this order:
lights/slam panel/rad/rad pipes (drain first) i remove these for easy access to remove the engine once it's on the crane
battery
clutch cable
throttle cable
wiring (make sure every single wire is unplugged and out of the way)
gear linkages
drain gearbox oil
remove driveshafts
remove bolts for exhaust downpipe (remove downpipe)
remove gearbox mount
Have your engine crane(or what ever your using) to take the weight and make sure it's not going anywhere lol
Remove engine mounts( i remove the mount that's connects to the gearbox as well, then once everythings free, slowly angle the engine and slowly remove it.
Anyone please correct me if i've missed anything
