It depends if you prefer to work on the engine on the bench or in the frame. I prefer the latter if for no other reason than it is held in position. I remove the head and barrel first I then remove all the timing side and then the clutch side. Because the barrel has been removed its easy to lock the engine to allow the shaft nuts to be undone. You are then left with the crank and crank case which can easily be lifted out single handed. Also with this method there is less damage to such as chips to the frame etc. All the best with it.

G'day John,
                I agree with Goldy. You can take the g/box out by it's self but much easier with the motor out.
Looking at your pics on the other thread either your head gasket or ex valve guide needs attention. The oil on the underside is more than likely from the breather due to wet sumping.
Cheers

Hi John,

And a welcome to the forum from me too.

I tend to remove the rocker box and cylinder head but leave the barrel on after slackening the nuts and making sure it's loose.  This way I'm protecting the pistons and rings whilst handling the lump.  In fact I would leave the barrel on until you get it to your mates place.

Oh, and make a note as to where the pushrods come from so they can be put back in the same places.  I put 4 holes in a piece of cardboard, mark them inlet n/s & o/s exhaust n/s & o/s and keep the pushrods bottom down in those holes.

Beezageezauk.
