thanks for info. Dave. those bolts on inside bearing look tough toI just replaced the jackshaft on my Noma 10 hp. It will make it easier to remove wheel shaft that has large chain sprocket on it. You will need to insert new jackshaft and bearings all in one piece and then bolt the bearings to the housing. Not a difficult job but a greasy messy one. Good luck!! Dave
I know this is an old post, but I have the same problem. I don't want to totally dismantle the tractor.Post some pictures. I can almost guarantee you I've done this before on one of those machines.
