Remove the support plate by unscrewing 4 Allen
screws M8x70 (pos. 3).
Remove the gear cover by unscrewing 6 Allen
screws M6x30 (pos. 4).
Note: If the gear cover is difficult to remove, it
can be levered off at the separating
lugs.
Remove the primary drive gear (pos. 5) (screwed
to clutch drum) and secondary gear (pos. 6) and fit
the gear pair of your choice.
Note: To allow fast exchange of gear ratios
we recommend you to carry in stock
various pre-assembled clutch drums
with the respective primary drive gears.
At re-assembly proceed in reverse sequence. Tighten the screws at the following torques:
M6: 10 Nm (88 lbf. in.)
M8: 22 Nm (195 lbf. in.)
Note: To allow easier matching of primary and secondary gears please note: The sum of
the last digits of the teeth number must always be 7 or 17 (35 / 62).
