Nope,its from the PB4500 back pack blower.Ill have to go look but i believe its a cw engine.Doesnt matter,but the crank for the hub is long like a ryobi long shaft and it has a flat keyway all the way down the shaft.So ill have to make a hub that slides over the shaft,somhow make a flat keyway,then just use a nut on the threads.Its a large shaft also,at least 3/8ths.It would be nice to use the other end but theres hardly no meat or threads there,just enough for the starter pawls to bolt on and thats it.Ill get a pic up maybe.Have you tried[bocabearing],thats where i get all my stuff.To order you go my the dimensions.Say your seal might be a 15x35x4===15mm ID[shaft size]35mm OD,block size4mm-seal thickness.I just ordered a seal for my A$M sachs 3.2.
