When the oil level has been checked and topped up if necessary, replace the oil seal or gasket I .

To remove the oil seal, push it outwards from its seat on the half-housing E.
Make sure that the new oil seal is the same type and size as specified in point 14
3
Fit the oil seal I on the half-housing E, pushing it fully into its seat. Use a special ring installer or a
suitable wrench socket, as shown in point 18.
4
Once having fitted the new oil seal I, before reassembling the half-housing E , wrap adhesive tape or
rubber-coated paper around the reduction unit-differential shaft, to avoid damaging the oil seal.
5 Apply lubricating grease onto the adhesive tape or rubber-coated paper.
6
Assemble the half-housing E , first inserting the half-axle into the differential, and then the shaft, taking
care not to damage the oil seal.
7
Centre the two reference pins on the other half of the housing, and couple the two halves of the housing
together by hand.
8
Tighten the four M6 screws O to a maximum torque of 9.5 Nm ~ 84 lbf in.

Spline the plastic joint N onto the reduction unit-differential shaft and insert the corrugated washer L .

Before assembling the rotor C , check wear of the two bearings H and M , making sure they are not noisy
or purple in colour, otherwise replace them.
11
Continue by checking the wear on the rotor switch C1 (where the carbon brushes slide), if dirty, clean by
blowing with compressed air, if slightly damaged clean using an abrasive cloth, while if there is excessive
wear replace the entire rotor
C .
