Bernina 830 cam gear cracked
Nylon cam gear on Bernina 830 (old 830 not new) is cracked from center to circumference. machine seizes once per revolution of this gear until manually crank through the rough spot, then runs until rotates enough and seizes again. How do i replace the gear and how do i ensure i have the correct part? Also, while i'm "in there," should i replace anything else? i'm willing to invest in the machine, say new belts, replace any known problem parts, etc.
