Hey, I ve recently acquired a NH 350 mixer grinder that has been sitting out in the weather. Looked it over best I could in the weeds. I spun everything by hand and nothing seemed sized till I got it home and found that the unloading auger was out of gear and slide collar was seized. Got it moving freely after lots of PB Blaster and beating to find that the lower bearing/bushing was seized and sheet metal started crumbling from being rusted out. So I took remaining bolts loose and removed auger shaft. I ve got bushing freed up, new sheet metal fabricated and tried to reassemble but I don t have enough clearance to install key in key way and slide shaft into drive gear. I m hoping someone can give me some pointers. Only way I can see getting enough clearance is to remove the drive shaft for the pivoting unloading auger. Thanks
