needle cage (pos. 10). The plain bearing has to be pressed flush into the bore of
the chain sprocket with chamfered end leading.
If not absolutely necessary on a certain track try not to use a chain sprocket with 11
teeth because of the heavy wear of the plain bearing (pos. 10) used only with this
sprocket.

teeth or on plain bearing (pos. 10) for chain sprocket with 11 teeth.

 Apply LOCTITE 243 on the thread of hex.nut (pos. 14).
 Note: A smaller thrust washer (pos. 13) is required for the chain sprocket with 11 teeth,
than when using the chain sprocket with 12, 13 and 14 teeth.
