I use the special tool and an impact.

Put the clutch plates back in but not the pressure plate then use an impact wrench and a correct size metric socket to shock the nut loose.

You can make a tool out of two old steel plates plus a handle bent out of 1/4" or 5/16" steel rod and a welder

Ok, update, here is what I am looking at. Thoughts? Things is, everything moves very smooth and transmission gears look spotless. All of that rust residue wiped rightout
of the bottom the case  ??? The other bummer thing is, i cant get my shifter rod all the way out because its bent at the end where the shifter lever ties on.

I would find another shifter (I may have one to sell) and just cut the bent end off and not take any chance on messing up the case half by trying to straighten it or anything else like that. Did you happen to loosen the primary nut before you disassembled the engine? It is a whole lot easier to do with the clutch basket in where you stuff a rag or penny the lock the gears and keep the crank from turning. I usually hit the primary loose then hit the clutch nut after. Looks like a lot of rust on those inners if the crank, I wouldn't trust those big end bearings. Don't give up, mine was in just as bad shape or worse!

Thanks Clem, what process did you take in restoring your crank? Did you rebuild it completely? Did you simply replace it all together?

Normally crank rebuild means pressing apart your crank and rebuilding it with fresh bearings.Some people use RG500 bearings and other trick stuff.I will listen since IŽm soon the same way down.

Yeah I was curious as to where he sent it to get rebuilt or if he did the work himself or just replaced the crank with a new one. Im not sure I catch your last sentence. Are you saying you are in the same spot?

I sent the crank out to Lyn Garland in Georgia. I don't have the pics on me now (I'm about 200 miles offshore currently)  but it was crusty and came back looking like new. I have had a few missed shifts up to 12k and it's held up fine. I believe that he goes by vintagespeciatlies.
