Hmm, was not able to align the punch marks as described in the workshop manual.

If I follow the procedure, the spring on image 3 is way too loose. If I turn it all the way around it will be too tight. Got advice from guys on FB and will ignore the punch marks. Mounted as on pic 1 and after the case is closed I will rewind the ratchet wheel 3/4 of a turn to give the correct tension. The rachet wheel is outside the crank case and can easely be adjusted. By the way, the punch marks were also wrong on my GT750 engine.

Don’t forget to mount the gears for the oil pump and tachometer:
