12.2.3. Removal of the bearing of a wheel

Fig. 257. Details forward absorber racks in gathering with leading shaft and the case of the bearing of a wheel (self-stopped nuts are designated as S/S): 1 — bolts with шестигранной a head, 35 Нм; 2 — a plate with nuts; 3 — an assembly bolt (before removal to note its position); 4 — a bolt, 10 Нм; 5 — the gauge of frequency of rotation of a wheel; 6 — nut S/S, 95 Нм; 7 — амортизаторная a rack; 8 — a leading shaft; 9 — a spring lock ring of the bearing; 10 — a bolt, 10 Нм; 11 — a reflector; 12 — the wheel bearing; 13 — a nut, S/S, 35 Нм; 14 — the case of the bearing of a wheel (a rotary fist)

Fig. 259. A nave of a wheel with details subject to removal: 1 — a gear wreath (ABS); 2 — a wheel nave; 3 — the screw with crosswise шлицем; 4 — a brake disk; 5 — the screw with crosswise шлицем; 6 — a 12-faced nut of fastening of a shaft of a drive of wheels; 7 — a bolt of fastening of a wheel, 110 Нм; 8 — brake колодки; 9 — скоба the disk wheel brake mechanism; 10 — fastening bolts скобы the disk wheel brake mechanism, 25 Нм

Details of the bearing of a wheel and the details connected with them are presented on fig. 257 and 259. It is necessary to pay attention to a gear wreath, привернутый to an inside of a nave of a wheel which concerns antiblocking system (ABS).

For removal of the bearing of a wheel it is necessary to execute following operations:

- To disconnect a brake disk;

- To establish under a press a wheel nave together with the case of the bearing and a reflector and it is cautious выпрессовать it by means of corresponding оправки. Not to damage a detail, a rotary fist to provide with a reliable support. On fig. 265 the tool used on car-care centre is shown. In drawing necessary support are well visible;

- To turn away a reflector;

- To take out the lock ring which is in the case of the bearing, then to take out an external lock ring (fig. 266);

- выпрессовать the bearing, having established its case (a rotary fist) on a press table so that the fixing ledge was above (fig. 265 see). This time the press rod should be established on an external ring of the bearing. Thus выпрессовывается only an external ring of the bearing. The internal part of the bearing remains on a nave of a wheel and acts in film a stripper shown on fig. 267;

- If it is necessary, to remove gear wreath ABS from a wheel nave, but to do it follows only in the event that it is supposed to replace a nave or a gear wreath.
