AGMA 9 Outside Diameter Tolerance

[GeneAinsworth]

Please help this rookie find out the Outside or Major Diameter tolerance for a AGMA Class 9 Spur Gear.
In particular, is there a certain specification covering this question? Or a formula?

Thanks in advance...

There is no standard but there are recommendations for each diametral pitch regardless of the AGMA Quality number. See AGMA 370.01 Design manual of fine pitch gearing. A newer version is AGMA 917-B97.

N+2/DP = standard OD
(#T+2)/diametral pitch = Do standard +/- .00x tolerance
