CAUTION:

Always replace the intermediate sprocket. Otherwise the backlash will not adjust itself and it could result in engine damage.

The new intermediate sprocket has an anti-friction coating that wears off after a short period of use, which automatically adjusts the backlash.

-- Tighten using a new bolt, in four stages as follows:

Stage	Bolts	Tightening Specification/Additional Turn
1.	-1-	Tighten to 10 Nm
2.	-1-	The intermediate sprocket must not have any play. Loosen and tighten it again if necessary.
3.	-1-	Tighten to 25 Nm
4.	-1-	Tighten 90° (1/4) turn further using a rigid wrench.
