Not exactly what you want to know, but early D14's had 92 teeth on the ring gear, and later ones had 116. But I doubt thats your problem, as when we had the 114 tooth starter in a D15 with 116 tooth ring gear (92 and 116 tooth flywheel/ring gear on D14 and D15 are the same), we just wiped the Bendix out on the starter.
The agco book shows the CA as having a 90 tooth ring gear.
I don't know about the D14, but on the D15 with the starter off, we found a way to use a big screw driver to slowly turn the flywheel, and count the teeth whale looking in through where the starter goes (mark the first tooth with something white or sliver (pen, paint, chalk)).
