CAUTION:

Danger of damaging the drive chain because the bolt thread is too long.

Use bolts with a 22 mm maximum thread length -a- to attach the T40049.
If only longer bolts are available, then the bolt head must be installed in such a way so that thread length is still 22 mm only.

-- Install the T40049 with 2 bolts -arrows- on the back of the crankshaft.
