INSTALLATION OF OVERLOAD
CLUTCH AND ENGINE WITH REAR
AXLE
NOTE
The overload clutch is the link between the en-
gine and the rear axle of the kart. In case that
the rear axle has been blocked by (e.g. break-
ing), the overload clutch is slipping slightly and
is not transferring the peak load from the rear
axle to the engine.
The plain bearings (pos. 2) are inside of the
overload clutch (pos. 1).
