The auger runs on a solid shaft that runs the full width of the blower. If you take the chain off and remove the large bolts from each side, the auger/axle assembly will come right out. I’ve found on the few machines I’ve had apart that the bearings are seized to axle. Unfortunately, you have to remove the shaft from at least one of the side bearings to get the axle out of the auger. I ended up using a cutting torch to blow the balls out of one side, allowing me to remove the axle. Once it’s out, it’s much easier to remove the bearings. I’m sure our suppliers can furnish the replacement bearings. I’m fairly certain they’re common enough, you could get them from a bearing supplier. I believe I put sealed bearings in the blowers that I have worked on. Nick From: Hank Ralston [mailto:Hank RalstonAgency com]

Subject: Re: (ET) Snowblower issue: Pivot bolt bad? Hm. What's the way to get the auger off? Take off one side of the blower?
