The auger bolt goes in to a short axle stub. This has a 3/4" hex on it and must be held to remove the bolt. You need a very thin 3/4" wrench ... like an old tappet wrench. When I first started working on these I found an old POS wrench and took the grinder to it ... thinned down and now used for nothing else.
As for the drive shaft bearing set screws, these are often rusted beyond consideration. New bearings should have retainers with them, and you won't easily get the bearing off either ... I go straight for the high speed cut off tool ... sacrifice the bearing ... why else would you be taking them off?
When reinstalling the chain and driveshaft, leave both sets of bearing clam shells loose until you have the chain tension set. Then the shaft sets up with no bow in it ... tighten them both after you like the chain tension.
