Yes ot has a flat area on the motor shaftIs there a flat milled on the motor shaft for the grub screw to bite into? If so, is the pinion grub aligned so it mates to the milled flat? Is there any grooving on the motor shaft that indicates the shaft is turning inside the pinion until the grub leaves the flat and breaks? Are the threads in the pinion gear cut full length to ensure the grub screw fully engages the shaft? Is the grub screw the correct thread to match the pinion gear threads? Is the wrench used for tightening correct for the grub hex?
Just some thoughts based on personal experience. For what it's worth. Regards. 'AC'
Thats exactly what in trying now i also got stronger grub screws to helpClean the grub screw and pinion with brake cleaner, put pinion in position, put a drop of thread lock in the grub screw hole in pinion, put in grub screw and allow to dry for 24 hours.
