Install brake discs B3 together in the order shown in illustration 12.6 and insert them one by one. Measure clearance «L» between snap ring (133f) and outer disc (133a) at three points. During measurement, the retaining ring (133f) must touch the upper race of the bearing in the groove of the outer brake mount (2).
Adjust the clearance with snap rings (133f), if it is needed. Retaining ring thickness: 3.2, 3.5, 3.8, 4.1, 4.4 and 4.7 mm.
