I have a Bolens 4021 24"-snow blower (Red one) , with Techumsa engine, I am attempting to rebuild. The engine is good, but the prior owner took out the shear pins and put in bolts, and hit something. The front spiral box gear,  a brass spiral gear is eaten away. The auger shaft gear is steel and ok. The gear measures 2-1/4" dia. the shaft is 1" diameter, with a 1/4" keyway. The gear is 1-1/8" thick, solid brass 20T. I have looked at the MTD-Troy built sites, they seem to use a similiag gear, but their shaft size is 3/4". with a 3/16" keyway.  I am sure of the model number, since that is what is on the plate on the back of the unit, Model 4021, ser. no. 0100826. I even have the users amnual with that number, which does not seem to corelletate to anything else. All I need is this one gear. Anyone have one or know where I can get one. I tried to navigate the MTD site, but they only have the smaller shaft gear. Email me at hager15@juno.com.

I bought (on ebay) a Cental Machinery one, almost exactly the same as the Troy Built one, all I needed as a hydrolic line from Northern Hydrolics and it was fixed. I used it with a generator in the woods, thing worked great! it is noisey. only part I don't like on the electric-Hydrolic is you have to hold the motor button down, while you hold the trip lever with the other hand. this sort of leaves you leaning over the log that's being split. I really don't like my face that close to that much force, even if it moves very slowly.
