Any best way to apply the Loctite 648 for glueing the pinion on the motor shaft ? Do you have to slightly sand the shaft ? Need a primer ? Alcohol ?
I just ordered it, but now I am reading that Loctite 680 is a better fit for this specific use … Dôh… Super expensive though !

Loctite® 680 Retaining Compound - Gives best resistance to dynamic, axial and radial loads. Recommended for retaining shafts, gears, pulleys, and similar cylindrical parts
little sanding on the shaft , acetone clean and dry
pinion : acetone clean and dry
measure the distance between the bottom of pinion and the bottom of the flange screwed to the gearbox , in order that the top of the pignon is flush to the gear of the gearbox
put glue on the Shaft and in the pinion
twist the pignon on the shaft at once no stop allowed, all the way , stopping at 2-5mm from the motor depending of the thickness of the fange
