Mein Duff

Hi Gang, I recently picked a older Saito FA 45. I need to replace the bearings, have it stripped down but can't get the prop driver to budge so I can remove the crankshaft. There is no Woodruff key, just seems to be some kind of brass or bronze sleeve type insert between thr Prop Driver and shaft. I heated the whole area pretty well and tried a gear puller...still wouldn't budge...this thing has probaly been on there 10-15 yrs.

This is my firts Saito attempt and I can't find any help on Youtube..or any forum help so far.

any tips would be apreciated..Thanks !
