There’s a small trick; if you have another O/D apart and can examine the guts. You need to line up the etched marks on the planet wheel (three small gears) with those on the planet carrier, before fitting the sun wheel to the carrier. Here goes:
Turn the planet gearwheels to align a punch mark (small round mark on the edge of one tooth) with one of three corresponding etched lines on the sunwheel side of the planet carrier. Then insert the sunwheel in the carrier, taking care to keep the gears in the proper position. Then fit the sunwheel/planet carrier assembly into the annulus; the sunwheel can then be withdrawn, if required. Then note the alignment of the eight splines in the center of the planet carrier (the unidirectional clutch, actually) If the carrier must be removed, then the gear wheels will need to be reset. Keeping all this aligned properly, in a vertical position, will permit the mainshaft to be inserted easily, without having to deal with that "last 1/4 inch battle".
