Allowable tooth to tooth spacing error shall be for coast side of tooth. , A. .001 for drive side of tooth. A.

.00065 (for 40 teeth or more). B. .00065 to -.001 (for 9 teeth of less) where + indicates the direction which produce a maximum material condition. Total index variation shall remain as stated in spline data.

Verification of tooth to tooth spacing error inspection is the CC.

Existence of the silver plate is the CC or Existence of silver plating on split cone journal and external splines.

For -102, -103, -105 AND -106, verification of acceptance of the spline, concentricity requirements to diameter Datum -D- is the CC or Concentricity of spline pitch diameter to 3.2460-3.2480 diameter.

For -102, -103, -105 and -106, verification of acceptance of the , concentricity requirements between diameter Datum -D- and -H- is the CC or Concentricity of 2.991-2.989 diameter to 3.2460-3.2480 diameter.

Nicks, dents, scratches, and tool or scuff marks within the CC area shall not exceed the acceptance limits per SS9208, para. 3.1 or Nicks, dents, scratches, and machining tool or scuff marks within CC area shall not exceed 0.0005 inch deep.

Shot peen coverage and verification in area identified as -g- is a CC. I.D. area requiring shot peen coverage shall be inspected in accordance with notes 26 & 30 or shot peen coverage verification of internal 1.00-inch radius.

The rc 30 minimum core hardness measured on the surface specified in the CC.

Verification of acceptance of parts by nital etch inspection for grinding burns per SS8705 in the area identified as -g- is a CC or Surface temper etch inspection.
