To measure rolling force:
-
Refit the planet gear carrier - DO NOT FIT THE SUN
GEAR. Use a spring balance and cord wrapped
around the planet gear carrier flange as shown. Pull
the spring balance so that the hub rotates and
record the reading.
-
To get the rolling force, subtract seal drag rolling
force (see step 14) from reading obtained at this
step, the result should be 64 to 117 N (14 to 26 lbf).
-
If the resulting figure is outside these limits check:
the seal is fitted correctly; and/or renew bearings if
necessary; and /or new fitted components.
-
Remove planet gear carrier.
17
Press the drive shaft thrust pad
C
(chamfered side
lowermost) into the recess in the planet carrier.
18
Fit new planet gears in place of any that were removed.
(See step 4 in 'Dismantling'). Secure with circlip.
Note:
Make sure that the SMALL radius on the gear bearing
internal diameter is facing uppermost, that is at the circlip
end of the planet pin.

Fit spacer and slide the sun wheel onto the driveshaft
and secure with circlip

.
Note:
Some machines may have an ‘ O’ ring instead of
sealant - where appropriate fit a new ‘O’ ring.
Note:
The sun gear must be fitted with the 1.5 mm (0.060 in)
x 45° chamfer inboard.
