MAINTENANCE ON CHASSIS AND ENGINE

Checking chain wear

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, bear-
ings 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.
