SAME SILVER 100.4 - Fitting the Rear Axle Half-Shafts

Assembly of rear halfshafts
Each halfshaft is secured to the planet carrier of the relative
epicyclic final drive unit by way of a plate located in the seating of
the carrier and secured to the inside face of the halfshaft with a
bolt.
The correct positioning of the halfshaft in the trumpet housing is
determined by a set of shims A indicated in figs 5 and 6.
Proceed as follows:
— fix the halfshaft in a vertical position in such a way that it cannot
be rotated;
— press the bearing cups B and C into the respective seats of the
stub axle;
— locate the O-ring D and bearing E, slide the stub axle onto the
halfshaft, fit bearing F and then position the planet carrier;
— fit the flange H with the fully machined face directed toward the
halfshaft, then torque the bolt G (or the three bolts G, in the
case of a Silver 100.6) to 30 Nm (3 kgm).
— Turn the stub axle through about 10 revolutions and check that
the bolts are still torqued to the correct value.
— If the bolts have loosened, retorque to 30 Nm.
— remove the flange H and measure the distance X between the
face of the halfshaft and that of the planet carrier flange; now
refit the flange H, together with shims corresponding to the
distance measured, minus 0.02mm.
—For Silver 80 - 90 - 100.4 machines, smear the thread of the
single bolt with Loctite 270 and torque to 177 Nm (18 kgm),
For a Silver 100.6, smear the threads of the three bolts with
Loctite 270 and torque to 63 Nm (6,5 kgm).
