10.6. 4-step check points of types F4W71B and With - dismantling
1. The order of dismantling and assemblage of 4-step check points almost same, as for 5-step also differs performance of following operations.
2. Instead of operations on dismantling in items 17-34 (section 4 see) execute the following.
1). Check up a condition of gear wheels and check point shaft, presence on them of cracks and other damages
2). Check up a face backlash of gear wheels and compare to the standard.
3). If damages are observed and люфт exceeds norm completely disassemble a check point and replace the worn out details
4). Press a stripper the forward bearing of an intermediate shaft.
5). Get a lock ring.
. Cautiously get intermediate and primary shaft.
7). Remove from a primary shaft a lock ring and a persistent washer.
8). Remove the synchronizer of 3rd both 4th transfers and a gear wheel of 3rd transfer.
9). Release a nut of a secondary shaft.
10). Remove a lock ring and a backing gear wheel.
11). Cautiously beat out from transitive section secondary and intermediate shaft.

3). On the intermediate platen establish an intermediate gear wheel of a backing
4). Tighten a nut of a secondary shaft with the set moment.
5). Раскерните a nut wreath so that the wreath has come into sample of a secondary shaft.
6). Again check up a face backlash of gear wheels.
