I need a final drive gear for a very old Buffalo hand blower (approx 12"). It is a helical gear, 1-1/8" dia. X 1/2" thick with a 1/2" bore. I haven'tdetermined the pitch yet. It has a cylindrical keyway for about a 1/8" rod. It is magnetic, so I think it is steel. Anyone know of any place where this gear may be obtained? Buffalo or otherwise. I know how to fix it, (not many teeth are bad) but I would rather get a new one, and have the vender identified, and available. It works but is noisy as heck (about 5 times per crank revolution) and has a limited life. . . . .Incidentally, out of curiousity. . .When I purchased the blower, it came with a 11" wheel, 5/8" flat rim, and has a 3" cylindrical hub that is bored and threaded on the outside for a set screw. And is center bored for a 1/2" shaft, same as for the hand crank. This hub has, on the inside, (about 2.5 "dia. X 1" deep), a sawtooth set of groves, longitutionally alligned with the shaft, set up for some type of a ratchet. The outer rim of this wheel is flat, as for a belt. Now, this blower does have its separate, adjustable, counterbalanced, hand crank. There was no ratcheting mechanism when I obtained the blower, and there is no hand crank handle on the wheel, or a place for one. I do believe both the hand crank and the wheel could be both mounted on the shaft at the same time. The handle would have to poke through the spokes. I'm wondering if the wheel is to make the blower free wheeling in one direction, when power driven????? any ideas ???? . . . thanks to one and all who may be of assistance.
