Check that the chain is correctly positioned on the front and rear sprockets.
The chain open ends should be in the lowermost portion of the chain midway between the sprockets. Overlap the two ends and slide the master link pins in place from the inboard side outwards.
Locate the link plate to the pins.
Fit the clip (1) to the pins.
Warning! The master link clip (1) must be installed with the open end pointing away from the direction of chain movement.
