M620IE Timing belts

[Andyt]

I just took delivery of a pair of timing belts for my recently acquiredmachine. Think they might be the wrong ones as they have printed on them M750. does it matter? is it the same part for both models? can anyone help ?

As far as I recall the 600 and 750 share a common belt, the 900 is one tooth longer. Count the teeth on your existing and new belts just to reassure yourself though!
