4.3 Sprockets
• Usually Ridder installs sprockets onto the two basic output shafts (BOS) of most models (general
designaon: RW).
• Some models (such as RW-LK, RW-D, RW-LD) have:
• One special output-sha (LK) plus one basic output sha (BOS)
• One special output-sha (D) plus two basic output shas (BOS)
• Two special output-shas (L + D). (The L-sha is for installaon of a drum.).
• Some models or shas (BOS and/or special shas) are supplied without sprockets.
Thus it is possibly necessary, if applicable for the conguraon, to:
❶ Install necessary (oponal) sprockets on output shas or
❷ Interchange sprockets with necessary (oponal) sprockets on output shas.
Refer to the illustraon (step ❶ and ❷) that follows for the conguraon of sha keys (a, b),
retaining rings (c) and ring (d).
For more informaon on item numbers and models refer to the Ridder catalog or website at

* Sha LK-model: Installaon of a drum is also possible. Refer to §4.7/4.8.
** Sha L-model is for installaon of a drum. Refer to §4.7/4.8.
