Note: For the chain sprocket with 11 teeth, use the plain bearing (9) instead of the needle
cage (9). 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. 9) used only with this
sprocket.
Apply grease on needle cage (9) at use of chain sprocket with 12, 13 and 14 teeth
or on plain bearing (9) for chain sprocket with 11 teeth.
Fit the assembled clutch drum with the selected number of teeth.
Apply ERGO 4052 on the thread of hex.nut (item 15).
