ABSTRACT:
A method of assembly for a planetary gear train wherein long front gears of stepped long pinions are applied with markings on the end surfaces of tooth forms, the middle grooves of the second and third stepped long pinions are respectively provided with an assembling pin hole in the position at an angle 180 degrees opposite to said markings, and the long rear gear of the first stepped long pinion is provided with a spot facing on the end surface corresponding to the marking, the process comprising preparing an assembling jig composed of carrier-fixing plates at an angular interval of 120 degrees on the center of a boss portion, a spot-facing plate provided in the direction rotated 15 degrees on the center of the support shaft located between said carrier-fixing plates, and control pins supported on pedestals; assembling the stepped long pinions by inserting the control pins into assembling pin holes so that the markings on the second and third stepped long pinions are pointing to the same direction as that of the marking of the first long pinion positioned by the spot facing plate.
