REMOVAL - REFITTING DIFFERENTIAL BOX
1 - PRELIMINARY OPERATIONS
Stripping the gearbox .
2 - REMOVAL
Remove :
Retrieve :
Remove :
NOTE : the differential housing (7) has notches (A) - (B) making it easier to remove .
Place a screwdriver (8) in the notches (A) - (B) and use as a lever .
Continue to detach the differential housing by tapping on each side using a wooden shim .
Remove :
3 - REFITTING
Check that the centralising studs are present (10) .
Check that the joint face is clean .
coat the joint face with a thin, even layer of jointing compound (E15) .
Fit the differential (9) into the housing together with the bearing outer races (11) - (12) .
Fit : The differential housing (7) .
Fit :
Measure the step X of the extension .
1st fitting - Extension/differential housing (Where projection X of the extension = 10 mm) .
Fit :
Tighten :
2nd fitting - Extension/differential housing (Where projection X of the extension = 8,65 mm) .
Position :
Gradually tighten the extension bolts while turning the differential, until rotation becomes difficult, in order to correctly position the races and bearings .
Remove :
using a depth gauge [33], measure the distance between the joint face and the external bush of the bearing .
Calculation of the thickness of the positioning shim : Y - X + 0,1 mm = Thickness of the positioning shim .
Fit :
Tighten the bolts (13) to 1.5 ± 0.3 daN.m .
Tighten :
NOTE : this order of operations ensures correct alignment of the joint faces .
