A split sprocket assembly mountable on a shaft comprises a pair of substantially semi-circular sprocket halves, each of the sprocket halves having a mating face joined at a split line between the sprocket halves and having a concentric bore. Each of the sprocket halves further has a plurality of teeth provided about its periphery and a series of tooth pockets also formed about its periphery between each pair of adjacent teeth. A hub having a throughhole disposed around the shaft is disposed in the concentric bore. The sprocket halves and the hub include two sets of diametrically opposite, aligned apertures, each of the aligned apertures extending radially inwardly from one of the tooth pockets on the periphery of the sprocket halves and into the hub. A fastener is provided within each of the aligned apertures for joining the sprocket halves and the hub together to form a split sprocket assembly readily attachable and detachable from said shaft.
