I got so fed up with things loosening that I now have a $5 tube (Lowes) of blue loctite in my tool bag. This stuff works!!!!

I am guessing here, but your friction disk rubber wheel is sandwiched between two metal plates, held together with 3 bolts and those are what is coming loose?

If so, buy three new bolts, long enough to accomodate Nylock nuts, and replace the current nuts and bolts with the nylocks, or try the Loctite method.

Work fascinates me.

Friction discs do not take kindly to shifting while engaged and moving. Any chance you've been shifting it while it's still under power ??

Looked up your machine and it isn't the sandwiched style where it's two plates squeezing on a rubber ring. You still don't want to shift on the fly but it sounds like something is damaged in there. Either the bolts or the holes. Maybe a little locktite is in order to hold it together.
You can get some Loctite at an auto parts store and they sell it in packets for a buck or buck fifty. More than enough for this application. You want to get 222 or 242. Just a low or medium strength.


Is this the disc for your blower ?

Thanks much, just rechecked the machine, there is supposed to be a 1/8" key, part 71203 that slides into the shaft and the friction wheel hub, apparently got ground up when the bearings on the hex shaft broke. Of course I cannot find the part.

Is it just a straight key or is it the half moon style ? Might try auto parts store, big box store or hardware store with pictures and measurements.

I think you can find them at either Lowes or Home Depot.
