the direction of the thrust faces, and press
the new bearings on the shaft, pressing
against the inner races only. Press against
the thrust ring, locking it in its groove. See
the illustrations on the next page.
5. To install the seals, install the inner seal
retainer ring first. Place a light film of
grease on each surface before pressing in
the seals. The round spring of each seal
faces outward.
6. Install the outer seal retaining rings before
pressing in the outer seals; align the notched
ends of the retaining ring to straddle the
small vent hole drilled in the ring groove.
7. Grease all seals. Fill the cavity around the
spring in the seals with grease and install
the outer seals.
8. Grease the two O-rings and install them, in
their grooves, in the upper seal housing.
Apply a thin film of grease inside the hous-
ing bore to ease entry of the bearing(s) and
O-rings.
9. FOR 40 AND 50 MODELS ONLY:
Slip the bearing housing over the shaft. Heat
the housing slightly again. It is important to
slide the housing on squarely, and do not
use a hammer, or in any way apply impact
loads to the balls. If you use a hand press,
press only against the outer race of the
bearing. Only a light press is needed if
everything is lined up properly.
FOR 90 AND V4/V6 MODELS ONLY:
Slip the bearing housing over the shaft.
Support the bearings and driveshaft, using
Yamaha special tool #YB-06205-2. Heat the
housing slightly again. It is important to
slide the housing on squarely, and do not
use a hammer, or in any way apply impact
loads to the balls. If you use a hand press,
press only against the outer race of the
bearings. Only a light press is needed if
everything is lined up properly.
NOTE: When using special tool #YB06205-2,
the housing will slide on only part way; therefore,
remove the tool, slide the seal housing into place
as a spacer, reinstall the tool, and continue press-
ing the housing until it fully bottoms out; remove
the seal housing assembly.
10. FOR 40 AND 50 MODELS ONLY:
Install the spacer washer.
FOR 90 AND V4/V6 MODELS ONLY
Install the backup washer against the upper
bearing, with the dished center section fac-
ing upward.
11. Install the upper seal housing assembly being
careful not to damage the O-rings as they
pass the snap ring groove. Only finger pres-
sure should be necessary here.
12. Install the beveled circlip bevel-side upward.
13. Fit the driveshaft assembly into the jet drive
casing, and fill with grease. If using a hand
gun, pump very slowly so to not build up
internal grease pressure and damage either
the seals or the housing.
