you NEED a trans stand with the threaded tilt things on it. you need to remove the whole gearbox mount.
position the box on the stand with the gaerbox mount point at the front half of the stand. thats aprox the center of gravity. you need to tilt it over about 30 degrees to clear the startermotor hump on the bell housing from the tunnel
also to did engage the clutch fork use a long screwdriver with a small bend in it to wedge indetween the release bearing and diaphapm spring bearing retainer (holding the spring clip thing hard against the clutch cover) and give the fork a jerk and the bearing will pop out.
dont try to pull the pin on the linkage out. its just makes it more akward.
apart from that its pretty easy.
a good quality pair or 12mm open end spanners is a must for the front prop shaft. as they seem to get very tight.
