Pfaff 545 Adjust Hook to Needle Distance

[friquant]

Is there a video on adjusting the hook to needle distance on a 545?

After my original hook broke, I am installing an aftermarket hook and the new hook bumps into the needle so I'm adjusting.  I have the hook saddle loose, but how to move the bevel gear so it still fits well against its mating gear?

Here are photos of the Pfaff 545, since they are somewhat different than what the 1245 service manual shows.

To adjust timing: loosen the two screws at A.

To adjust hook-to-needle distance: Loosen the two screws at B (to move the hook saddle) and also loosen the two screws at D and the two screws at E (to adjust the new mating distance of the bevel gears.)

As for the two screws at C, they do not need to be loosened. One of the screws at C is resting on a flat spot ground into the hook  driveshaft, so that's why you have to use the screws at A to adjust timing.
