Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Transmission>> Mechanical transmission>> Differential

Fig. 8.32. Differential: 1 — a semi-axis flange; 2 — a lock ring; 3 — уплотнительнов a differential ring; 4 — a speedometer drive; 5 — a conducted cogwheel of the main transfer; 6 — a differential box; 7 — the differential bearing; 8 — a compensatory washer; 9 — a sealing ring of differential; 10 — a lock ring; 11 — a driving flange; 12 — semi-axial gear wheels; 13 — satellites; 14 — an axis of satellites; 15 — a separator; 16 — a secondary shaft; 17 — a gear wheel of a drive of a speedometer; 18 — the differential bearing

Dismantling of differential carry out in the following order (rice 8.32)
carefully clear and examine differential. In the presence of wear or damages replace it. At replacement of a conducted cogwheel of the main transfer replace a secondary shaft as they are coordinated with each other;

Fig. 8.33. Drilling of rivets of fastening of a conducted cogwheel of the main transfer to a differential box

for removal of a conducted cogwheel of the main transfer, a drill in diameter of 12 mm drill rivets of fastening of a cogwheel to a differential box (fig. 8.33) and remove a conducted cogwheel of the main transfer. Protect differential bearings from metal shavings which are formed when drilling. At installation of a conducted cogwheel of the main transfer use special bolts with nuts;
stripper, press bearings from a differential box. Before removal of bearings previously remove a speedometer drive;
drift from soft metal hammer against the stop a spring pin into an axis of satellites and, striking blows to an axis end face, beat out an axis of satellites from a differential box;
take from a differential box satellites, semi-axial gear wheels and a separator;
drift from soft metal beat out a spring pin from an axis of satellites.
Assembly of differential carry out in the following order:
check a condition of details of differential;

Fig. 8.34. Arrangement of a spring lock pin (1) fastening of an axis of satellites. Length of a pin of 28,5 mm

oil a separator, establish it in a differential box. Insert satellites and an axis of satellites. Turn an axis of satellites so that openings in a box of differential and an axis of satellites for installation of a spring pin were combined and hammer a spring pin so that it entered almost to the middle of an axis of satellites (fig. 8.34) ;
establish from two parties of a box of differential semi-axial gear wheels so that axes of semi-axial gear wheels coincided with an axis of a box of differential;

Fig. 8.35. An arrangement of two directing bolts (And), for orientation of a conducted cogwheel at its installation on a differential box

insert two special bolts (fig. 8.35) of fastening of a conducted cogwheel of the main transfer from two opposite sides into a differential box. Before installation heat up a conducted cogwheel of the main transfer to temperature of 100 °C and establish it on a differential box;

Fig. 8.36. An arrangement of bolts of fastening of a conducted cogwheel of the main transfer to a differential box

establish new special bolts (fig. 8.36) , nuts and lock washers and tighten nuts the regulated moment;
establish a gear wheel of a drive of a speedometer and new conic bearings;
temporarily (without lock rings) establish drive flanges in differential and check its work.
