11. Install the thrust bearing (9) on the output shaft.

NOTE: Use petroleum jelly to hold the thrust bearing in
place.

12. Align planetary pinions.  Each pinion is marked with

double points to indicate the master tooth space and
exactly opposite with a single point to indicate the
master tooth.  The markings on the planetary carrier
consist of double lines which are to be lined up with
the double points on two opposite pinions; the single
lines are to be lined up with the single points on the
other two pinions.

D

After all four pinions are lined up, slide on the third
clutch assembly. Rotate third clutch and check
mark alignment. Considering that the ring gear
tooth between the double points of one planetary
pinion is tooth number 1, count the teeth to check
that the single points on the two adjacent pinions
are between teeth 23 and 24 of the ring gear, and
that the ring gear tooth between the double points of
the opposite pinion is tooth number 46. If the ring
gear and pinions are not lined up, remove and
realign them.
