NOTE:

There is a risk of destroying the toothed belt by bending too sharply. The toothed belt is made out of a fiberglass cord webbing, that can be damaged by bending to sharply.

Never bend the toothed belt with a radius less than 25 mm.

The bend radius -r - on the toothed belt -2- must for this reason not be under 25 mm (approximately half the diameter of the toothed belt -1- on the crankshaft).

-- Install the toothed belt -1- on the crankshaft toothed belt sprocket -2- from underneath.
