12.29 Checking the chain tension
Warning
Danger of accidents Danger caused by incorrect chain tension.
– If the chain is too taut, the components of the secondary power transmission (chain, chain pinion, rear sprocket, bearings
in the transmission and in the rear wheel) will be under additional load. In addition to premature wear, this can cause the
chain or the countershaft of the transmission to break in extreme cases. If the chain is too loose, however, it may fall off
the chain pinion or rear sprocket and block the rear wheel or damage the motor. Ensure that the chain tension is correct
and adjust it if necessary.
