New item 12/01/13! Standard 16 tooth jackshaft/sprocket assembly for 48" snowcasters with roll pin mounted pulleys. Replaces p/n C19732. Earlier models with keyed pulleys and sprockets also require a p/n C31953 pulley to use this shaft. Fits both the current RM48 model as well as the earlier 84 series. Measures 25-3/4" overall so the drive pulley must be install opposite of the original position on 84 series snow casters.
