No help yet? Well here goes , with the rear cover off I mark the rear of the rod with a small vertical scratch on the rod , I also mark the rear of the cylinder head the same way(it will go on 180 o out but this way you can use head gasket over). Remove the head & stick your thumb in cylinder & try to pull sleeve out , if your lucky it will come ( don't sweat location , has a alignment pin). If it don't come out , put a prop on crank & I use a old glow plug washer & drop it in cylinder & catch it in exhaust port , turn prop over & sleeve will slide up , should come out now . Don't force too much , may need to heat with heat gun & try again (wear glove) . With sleeve out rod will now come off crank pin . Remove prop & prop washer, tap on crank with wood block or wrap end of crank on bench top . Front bearing will come out with a wood dowel or brass drift & hammer( heat will help) . Large bearing removal is a little more of a problem , I have always got by with heating it with a heat gun & hitting rear of crank case on bench or wood block( glove again) . May need to repeat . Some put case in oven but have never needed this ( oven is for cooking & engines taste awful). Assemble in reverse , heat case & maybe cool bearings in freezer, line up with crank when installing. Don't force ! You can use gaskets over if you don't break rear cover one , put head gasket on in same position & it should work . Tighten bolts evenly. You probably have 6 answers by now ( one finger typer)Oh well , good luck & stay out of the woods , the bears will get ya ! MAX H.
