Trans/axle
Here is a picture,there is a enclosed trans assembly that covers the rear axle,I haven't had this apart,but,there must be an internal chain from the top where the engine belt go's to,down to the axle that must also have a sprocket on it,this is all enclosed in a straight 30 weight oil bath that is fillable near the top part of the assembly.The top part has a bearing with a shaft coming out of the assembly,this has the pully on it.One of these complete assemblies was recently on ebay:thumbsup:
