Adjusting chain tension
Warning
Danger of accidents Danger caused by incorrect chain tension.
–
If the chain tension is too high, the components of the secondary power train (chain, engine sprocket, rear sprocket, bearings
in transmission and rear wheel eccentric element) are under additional load. Apart from premature wear, in extreme cases the
chain can rupture or the countershaft of the transmission can break. On the other hand, if the chain is loose, it can fall off
the engine sprocket or the rear sprocket and block the rear wheels or damage the engine. Check for correct chain tension and
adjust if necessary.
–
Park the vehicle on a horizontal surface and shift gears to neutral.
