Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Transmission>> Mechanical transmission>> Dismantling, check of a condition and assembly of primary shaft
Dismantling of primary shaft carry out in the following order:

Fig. 8.15. Shaft and five-speed transmission gear wheels: 1–coupling case; 2–adjusting washer; 3–conic bearing (small); 4–secondary shaft; 5–conic bearing (big); 6–washer of round section; 7–bearing support; 8, 22, 33, 46, 60 – a persistent washer; 9–gear wheel of the 1st transfer; 10-needle bearing (38х43х25); 11-synchronizer ring; 12, 14 – a spring; 13-synchronizer; 15, 29 – a cracker; 16-lock ring of the needle bearing; 18-synchronizer ring; 19-external ring of the synchronizer; 20-internal ring of the synchronizer; 21-gear wheel of the 2nd transfer; 23-needle bearing (30,6х40х26, 8); 24-gear wheel of the 3rd transfer; 25-synchronization ring; 26, 28 – a spring; 27-synchronizer; 30-needle bearing; 31-synchronizer ring; 32-gear wheel of the 4th transfer; 34-plug (29х46х18,1); 35-gear wheel of the 5th transfer; 36-plug; 37, 54 – bolt М8х26; 38-transmission case; 39-roller bearing (22х45х16,6); 40-primary shaft; 41-gear wheel of the 1st transfer; 42-lock ring; 43-gear wheel of the 4th transfer; 44-roller bearing (30х68,2х17,2); 45-adjusting ring; 47-needle bearing (29х40х24); 48-gear wheel of the 5th transfer; 49-synchronizer ring; 50-spring; 51-synchronizer nave; 52-the sliding coupling of the synchronizer; 55-plug (15х21х18); 56-intermediate gear wheel; 57-lock ring; 58-backing gear wheel; 59-shaft of a gear wheel of a backing; 61-plug; 62-holder of a shaft of a backing; 63-screw of longitudinal fastening of the holder; 64-screw of cross-section fastening of the holder


stripper remove from primary shaft 40 (see fig. 8.15 ) an internal ring of the roller bearing;
remove a stripper from primary shaft a persistent washer, the bearing and a gear wheel of the 4th transfer;
remove a spring lock ring from a flute of a shaft and a gear wheel of the 3rd transfer.
Check carry out as follows:
carefully clear all details of primary shaft and check their condition;

Fig. 8.14. Fastening of gear wheels of the 5th transfer on transmission shaft: 1–bolt; 2–spring washer; 3–a conducted gear wheel of the 5th transfer; 4–synchronizer nave; 5–synchronizer ring; 6–leading gear wheel of the 5th transfer


Fig. 8.16. Check of a gap "and" between a ring of the synchronizer and a gear wheel of the 5th transfer


check a condition of a ring of the synchronizer of the 5th transfer (fig. 8.14) , having established it in the sliding coupling and, pressing in the direction to a gear wheel of the 5th transfer. By an edge щупа measure a gap between an internal end face of a ring and a gear wheel which (fig. 8.16) should be no more than 0,5 mm .
Assembly of primary shaft carry out in the following order:
at assembly of primary shaft oil each established detail;

Fig. 8.17. Installation of a gear wheel of the 3rd transfer on primary shaft


fix primary shaft in a vice with slips from a soft material and, using a tubular opravka, establish a gear wheel of the 3rd transfer on a shaft (the fillet on a gear wheel should be directed to a gear wheel of the 4th transfer ( fig. 8.17 .);
fix a gear wheel of the 3rd transfer by a lock ring;
press on primary shaft a gear wheel of the 4th transfer (the fillet on a gear wheel should be directed to a gear wheel of the 4th transfer);

Fig. 8.18. Bearing installation on primary shaft


using a tubular opravka, establish on a shaft the conic bearing (fig. 8.18) ;
establish on primary shaft a persistent washer;

Fig. 8.19. A plug press fitting on primary shaft


establish the plug on primary shaft and напрессуйте it into place by means of a tubular opravka (fig. 8.19) ;

Fig. 8.20. Installation of the conic bearing on primary shaft from coupling installation


using a tubular opravka, напрессуйте the conic bearing on primary shaft from a coupling case (fig. 8.20) ;
external ring of a conic roller bearing press in a transmission case without compensatory washers;
establish primary shaft in a case;
collect a case of a transmission and tighten bolts the demanded moment.
