To All, I recently picked up a 79361 44" 2 stage snow blower and when cleaning it up I found the impeller to be in very rough shape. Surprisingly the housing is in good condition. My plan was to disassemble the auger system and remove the impeller and bearing to see if I could resurrect the impeller. It looks like it will take a lot of work to get the arms heated and bent back into the original position, not to mention maybe adding some material on the leading edge of the impeller arms. I am looking for a good impeller and while I'm at it see about replacing the auger end brass bearings with real ball or roller bearings. I never stop upgrading, I am also looking for the center support for the gear case assembly to the upper housing to relieve some of the gear case movement. I had seen photos of such a bracket system on other blowers but no idea if someone has put together a kit or it is a do-it-yourself bracket assembly. I would sincerely appreciate any input from members who might have a good impeller for sale and or any knowledge of installing auger bearings and possibly the support for the gear case. At any rate, Merry Christmas to all and Happy Holidays to those who prefer the latter. Best regards, Anvil

My 520xi mounted snowblower is vibrating like crazy. The collars on the jack shaft both came loose and cracked. I pulled the front half of the unit apart after taking the chain off and the jack shaft feels smooth and has no lateral movement. I noticed my chain is very stiff and worn on one inside edge. My impeller was bent a few years ago and I did my best to straighten it out on the maching. I didn't have a wheel puller and could not pull the sprocket fron the impeller shaft. It is my belief that the impeller is still bent enough that it is way out of balance.. could that be causing the vibration? Could the chain be causing the vibration? The chain was very loose. The vibration is so severe that the drive pully is coming loose and dropping its key. I have to tighten the set screws very tight and that makes me nervous. There is a very light bend in th ejack shaft as the pully does move very slightly up and down while rotating.. Any ideas? Where to start, what to eliminate? I think the blower has maybe 25 hours on it since new. Thanks!! Mark
