Re-assembling
Press on the bearing inner races (1) using tool [3]
Refit
- The friction washer (2) (lubrication channel: the sun wheel side)
- The sun wheel (3)
- The planet cage (4 - 5)
- The cups (6 - 7)
- The shaft (8)
- The sun wheel (9)
- The friction washer (10)
Refit the flange (11)
Fit the crown wheel (12)
Fit the bolts (13) (tightening torque to 8.0 da.Nm)
Clip the speedometer drive gear (14)
Checking the sun wheel end float
Fit
- The tool [19] on the sun wheel in line with the teeth (side opposite to the speedometer gear)
- Dial gauge support (in kit 4123.T)
- The pin [20]
- The dial gauge [24]
- Set the dial gauge to zero
- With the aid of two screwdrivers, measure the sun wheel end float
- Take 4 measurements at 90 °
WarningThe minimum clearance must not be less than 0,10 mm
Fit
- The tool [19] on the sun wheel in line with the teeth
- Dial gauge support (in kit)
- The pin [20]
- The dial gauge [24]
- Set the dial gauge to zero
- With the aid of two screwdrivers, measure the sun wheel end float
- Take 4 measurements at 90 °
- The maximum end float must not be more than 0,10 mm
WarningIf one of the measurements is above this value, replace the appropriate friction washer
NoteThe friction washers are available in 8 thicknesses (1,94 - 1,87 - 1,80 - 1,73 - 1,66 - 1,59 - 1,52 - 1,45 mm)
Tool for adjusting the sun wheel end float [19]
WarningAfter final assembly, check the drive torque of the differential, using tool [21] the torque must not be more than 1.0 m.daN; if it is higher, increase the end float of the sun wheel on the side with the lower end float
