Spread the rollers (6) with grease and set them c.w.rings (4)
in the seats of planet gears (5). Set the planet gears (5) and
relevant thrust rings (3) in the spider (7) and use a feeler gauge
to check that backlash of gears is 0.10 to 0.70 mm.
In case of different value, replace the thrust rings (3). Fit the
pins (2) in the spider (7) and set them so as the ”0” marked
on the pins is turned to the spider holes for springs caps (1).
Fit the spring caps so as they are bedded 0.5 mm lower than
the spider, then calk.
Fit the bearing (2) in the support (3) by making use of suitable
driver (4).
Fit in place the spring retaining ring (1) and check that the axial
backlash is 0 to 0.1 mm. In case of higher value, select the suit-
able thickness ring out of those supplied spare.
Fit the support (3) in the crown gear (2) and lock with spring
retaining ring (1).
Fit the coupling element (2) and relevant synchronizer ring (1)
in the support (3).
Heat the hub (1) at 85
°C for 15’, then fit it on the support shaft
(4) by making use of suitable driver.
Fit the spring retaining ring (2) and use a feeler gauge (3) to
