Alternator mounting studs (1964 N15CS)

Alternator has packed up. Upon dismantling, I find that the three mounting studs are 3/16ths & the holes in the stator are 1/4 inch. Are these studs correct? I expected to find 1/4 inch shouldered studs which would fit the stator holes snugly. Is this a previous owners bodge to get some adjustment in the stator/rotor air gap?

The stator is located by it's outer diameter in a recess in the primary drive cover. This cover in turn is located by two dowel pins.

Nope not a bodge. On the later models the reduced studs were used to allow the air gap to be set.

Thanks you Gents. So I presume it's tape round the rotor, fit outer case with stator nipped up, hope rotor centralises stator, remove case & fully tighten stator?

Yep that's how I centralise mine.
