Chipper model help

[fireball33]

Recently purchased a chipper not sure the model any help appreciated…. It has a ford 300 6 cylinder and 12 inch wide drum. It a chuck n duck style chipper. I took the clutch out and seems the pilot shaft bearing is bad I ordered a new one seems a little loose inside the flywheel. Anyone have experience replacing the clutch and pilot shaft bearing? Or anyone have a chipper that looks similar the belt guard on most is straight across the top this one is on an angle?

Thanks for looking
