Checking the shock absorption rubbers in the rear hub *
LC4 models have a damped rear wheel hub. For this purpose, the engine
power is conveyed from the rear sprocket via 6 shock absorption rubbers
5
to the rear wheel. These 6 absorption rubbers wear with increasing
operation time, and should be checked for wear whenever the rear wheel is
dismounted.
For this purpose, lie the rear wheel on a work bench with the rear sprocket
upwards, and put the wheel spindle in the hub. Now hold the rear wheel
firmly and try to turn the rear sprocket. The rear sprocket may not turn
more than maximum 5 mm (0,2 in) measured on the outside. If the play in
the chain wheel is larger, all 6 shock absorption rubbers are to be replaced.
Check the shock absorption rubbers for signs of damage and dirt.
!
CAUTION
!
IF THE SHOCK ABSORPTION RUBBERS ARE NOT REPLACED IN GOOD TIME, THE REAR
SPROCKET CARRIER AND THE REAR HUB WILL BE DAMAGED
. ALLWAYS REPLACE ALL
6
ABSORPTION RUBBERS, NEVER SINGLE RUBBERS.
