This will release the shaft, which can be lifted or driven out upward. This instruction applies equally to the removal of any one of the parts mounted on spindle 427, except the lower gear, which may be removed by merely following Instruction No. 23 and driving out the taper pin in its hub.
No. 28.^To Remove the Upper Sprocket, 443, P. 3, drive out the taper pin in its hub and pull sprocket off its shaft. The shaft may also be removed by driving out taper pin in gear 444, P. 2, having first removed the sprocket, of course.
