About those barrels
I just ordered barrels for my 3185 - I foolishly drove it with the shaft making noise back to the shop. Stupid. It broke and damaged several other hard-to-find parts. It also lost a set of the barrels. They are not plastic, they are rubberoid things. There are eight of them nested inside the adapter - held on their outside. The shaft has a end that looks like a cog, but isn't. It fits in the middle of the barrels tightly and all the rotating force is carried through that joint... And the 3185 has the barrels at both ends of the drive shaft. I see it as a joint that allows some slight bending without a u-joint, and that probably absorbs some of the shock of sudden stops and starts. They apparently rarely give trouble, but are hard to access. I had to remove the engine and am awaiting several parts - and two barrel kits (cause I dropped one from the complete set and can't find it). Actually the job itself isn't all that difficult and, since I don't live anywhere near a Cub Cadet shop, it's a do-it-yourself job.
