Checking the chain guide

Fig. 41 Example of a defective chain guide
Since the chain sprocket is usually replaced together with the chain set,
no further check is necessary under normal conditions.
However, if you notice any uneven or harsh running in the chain drive
mechanism, this may indicate wear.
The chain guide must be removed and degreased to enable the chain
sprocket to be inspected properly.
If the chain sprocket shows signs of wear from the chain or chipping on
its sides, the chain set must be replaced without delay.
The chain drive can move easily on the drive shaft, i.e. lateral play of
approx. ±2 mm is normal. A defective chain guide must be replaced im‐
mediately:
● Open the service cover.
● Check the chain guide for any damage, e.g. ruptured guide section
halves or loose bolts.
