A method for synchronizing multiple generators includes positioning a pilot feature of a shaft of a first generator positioned at a first angular position that is substantially aligned with a first predetermined reference point located at a predetermined angular position relative to an axis, locking the shaft of the first generator at the first angular position, aligning a pilot feature of a first shaft of a second generator with a second angular position that is substantially aligned with a second predetermined reference point located at a position relative to the axis that is substantially equal to the predetermined angular position, calculating an angular difference between the two angular positions, and rotating a second shaft splined with the first shaft of the second generator about the axis in another direction, based on the calculated angular difference.

We claim: 1. A method for synchronization of multiple generators in a gas turbine engine comprising the steps of:locking an input gear and an idler gear, wherein the input gear engages the idler gear;rotating a drive gear shaft, the drive gear shaft comprising a helical generator drive gear and a fine pitch spline, the drive gear shaft rotationally mounted on a thrust bearing assembly and coupled to a gear mounting flange via the thrust bearing assembly, wherein the generator drive gear is engaged by the idler gear;positioning the drive gear shaft to a desired degree of alignment with an intermediate shaft, wherein the intermediate shaft is connected to the drive gear shaft through the fine pitch spline;advancing the helical generator drive gear axially by varying a thickness of a shim to fine tune the degree of alignment, wherein the shim is disposed between, and engages, the thrust bearing assembly and the gear mounting flange;clamping the generator drive gear in position; andrepeating all the steps above for each additional generator to be synchronized.
