yoke, and turn this yoke ear to the bottom.
3. Insert cross into yoke so that the trunnion seats
freely into bearing cup as shown in figure 4A-14.
4. Install opposite bearing cup part way. Make sure
that both trunnions are started straight and true into both
bearing cups.
5. Press against opposite bearing cups, working the
cross all of the time to check for free movement of the
trunnions in the bearings. If there seems to be a hang-up,
stop pressing and recheck needle rollers, to determine if one
or more of them has been tipped under the end of the
trunnion.
6. As soon as one bearing retainer groove clears the
inside of the yoke, stop pressing and snap the bearing
retainer into place as shown in figure 4A-15.
7. Continue to press until the opposite bearing retainer
can be snapped into place. If difficulty is encountered, strike
the yoke firmly with a hammer to aid in seating bearing
retainers. This springs the yoke ears slightly. See figure 4A-
16.
