early 1962 Ariens 10M-L35 Sno-Thro impeller/auger bearing replacement repair

when I engaged the auger on this Ariens 10M-L35 blower, it made a steady clunking noise as the impeller turned. At first it sounded and looked like another bent impeller shaft. upon removing the top belt access cover, something didn't look right with the rear impeller bearing. at first I thought it had an engagement spring that had come apart and broken, this is what I saw

these early machines come apart very easily, only TWO bolts on top, one on each side, and both halves split apart pivoting on a shaft across the bottom of the machine, left to right. nice setup. I really like this. obviously the engineers at Ariens knew WTH they were doing and designed it with service ease in mind. This is what separates a good machine, from a so-so machine !! a well thought out design.

upon pulling the chute assembly and inspecting the impeller bearing, I saw this

next removed the 2 clutch chuck set screws, the clutch slipped right off the keyway and key, and revealed this

rut-roh !!

removing the 3 bearing flange nuts and flange, revealed this. all the ball bearings were GONE from the impeller bearing, and fell out sometime in the past. The machine was being run with the innner race, laying on the outer race, with remants of the sides of bearing covers still there on the shaft, and the impeller shaft had fallen down and was rubbing on the floor of the impeller housing, and making the "clunk-clunk-clunk" noise. the machine was running in this condition.

to pull the impeller/auger shafts assembly and gearbox, had to remove the upper strap support bolts, and the auger shaft bearing locknuts and flange hardware. later the strap can be loosened on the gearbox when the assembly is out of the chute.

the impeller/auger/gearbox drive assembly was removed out the front, with the keyway still on it. the ball bearings being missing, allowed it to pass through what remained of the bearing, i.e. only the races.

had the bearing been intact, the keyway would have to be removed first.

upon removing the assembly, there's the inner race still on the shaft, and keyway.

tapped the key out with a drift and screwdriver, and the inner race slipped right off. I wish they were all that easy ! (a similar repair on the Gilson 55012 required cutting the inner race off the impeller shaft with a torch last March)

the impeller bearing was completely destroyed, but the 2 front auger shaft end bearings were intact. one side was rotating a little rough when the bearing was checked by spinning it in my hand, and it had a small gouge in the side cover plate. the other one spun almost like new. I kept them for spares. a local bearing/drives supply house had them in stock for $9 each. I bought 3 of them, figured now is the time to change them, as all 3 are the same part. it also makes the machine work smoother with less drag on the engine and throw snow further. here's the new bearing in the flange and what remains of the old bearing

I make it a habit to coat any bearing, even though they are sealed, with grease, and the shaft ends as well. the auger shaft bearings had rust forming on the outer race surface. anything not greased or oiled will rust quickly in the winter, the brine and salt they use on the roads is extremely corrosive.
