Murray (Brute,J.D., Snapper, etc.) Disc Drive Wheel

Hi folks. Just wondering if anyone knows what would cause the drive disc (the metal platter) to move backwards toward the rear of the blower. I can"t disengage drive no matter how slack I adjust the wheel drive cable. I see the outer edge of the metal disc is touching the frame and causing some swarf buildup, so something is off. So close to the end of the season, now I got to be breaking out tools in the cold and trying to get this done. Currently have the neighbour"s driveway to do to, as he is off on vacation and I said I"d take care of things while he was away. I knew a Brute/Murray was a cheaper machine, but most winters here I need to use it maybe 4 times a season. I have had it for about 4 years now, and I"m not impressed that something like this would happen with maybe 15hrs of running total. Works quite well when I"m using it though.

Have you ever greased the spines? It sounds like it might be stuck, although it should not be rubbing on anything. They do require some routine maintenance, I check mine over every fall before Halloween, I will never forget that storm!

Found the problem. A bearing in blind hole was creeping out allowing the drive disc to move backwards, permanently engaging the rubber wheel. I used a hammer and a wooden drift to force the platter forward back onto the bearing. It now has about a quarter inch of clearance and the shifting has returned to normal. I"ll probably remove the assembly in the spring and put some Loctite bearing retainer on it, or drill through the disc into the shaft the bearing sits on and install a countersunk bolt to hold the platter to the shafts more securely.
