86 — the Output shaft
163, 186, 190 — Blocking rings
166 — Laying
168 — Drove
169 — the Persistent bearing
170 — the Crown gear wheel
171 — the Solar gear wheel |
172 — Coupling of the raising transfer
187 — the Internal disk
188, 189 — External disks
191 — the Cam spring
192 — the Piston of a brake of the raising transfer
195 — the Damping spring |
|
|
1. Remove a back cover of the transmission.
2. Remove the leading shaft (86), having removed a lock ring (165). |
| 3. Remove a crown gear wheel (170). Remove laying (166) and the persistent bearing (169) from an output shaft (167). Take drove (168) of a crown gear wheel (170). |
|
| 4. Remove a solar gear wheel (171) and a crown gear wheel (170). |
|
5. Remove coupling of the raising transfer (172) with the block of disks.
6. Take the block of disks of a brake of the raising transfer from the case, having removed a lock ring (186). |
| 7. Remove a damping spring (195). Remove a blocking ring (190) and a cam spring (191). |
|
| 8. By means of nippers take the piston of a brake of the raising transfer (192) from the case, remove teflon rings (196), and then a persistent washer (173). |
|
|
Installation
|
|
| 1. Before installation of a persistent washer (173) be convinced that the lubricant opening (shooter) is installed in the transmission case. |
|
| 2. Grease both sealing rings of the piston of a brake of the raising transfer (192) with gearbox oil, press the piston in the case, insert a persistent washer (173) so that the antirotational edge settled down in the case, screw teflon rings (196). |
|
| 3. Insert a cam spring (191), establish a blocking ring (190), establish a damping spring (195). Establish disks of a brake of the raising transfer individually. |
|
| 4. Carefully insert a support of coupling of the raising transfer (17) to a multidisk brake of the raising transfer. |
|
| 5. Carefully insert a crown gear wheel (170) into a brake of the raising transfer. |
|
| 6. Insert a solar gear wheel (171). |
|
| 7. Insert drove (168) in a crown gear wheel (170), be convinced that the internal persistent bearing (169) took drove, fix the external persistent bearing (169), establish laying (166) on an output shaft (167). |
|
|
Check of an axial gap between output and intermediate shaft
|
|
| 1. Measure distance of "a" from the contact surface of the bearing of an output shaft (86) to an internal ring of the bearing (198) by means of a caliper. |
|
| 2. Define distance of "b" from laying (166) to the roller persistent bearing (169) by a caliper. |
|
| 3. Adjust an axial gap "with" laying (166), having determined laying thickness: Distance of "a" (18.00 mm) - Distance of "b" (16.60 mm) = the Difference (1.40 mm) - the Axial gap (0.10 mm) - the laying Thickness (1.30 mm). An axial gap between output and intermediate shaft of 0.10 mm. Laying 0.1, 0.2 and 0.5 mm thick is issued.
|
| 4. Establish an output shaft (86) and insert a blocking ring (165). |
|
|
Check of an axial gap between an output shaft and a back cover
|
|
| 1. Measure distance of "a", having established a measuring disk (028) on a contact surface of a back cover. Define distance from a disk (028) to an internal holder of the ball bearing (67) and the help of a caliper. |
|
| 2. Establish a measuring disk (028) and a flange. Block a doggie of the parking brake in working situation. Tighten a nut (62) to 100 Nanometers. Establish laying (72). |
|
| 3. Measure distance of "b" between a measuring disk (028) and laying (72). |
|
4. Adjust the axial gap "Е" laying: Distance of "a" (118.80 mm) - Distance of "b" = the Difference (1.90 mm) - the Axial gap "Е" (0.40 mm) = the laying Thickness (1.50 mm). The nominal rate of an axial side play between an output shaft and a back cover makes 0.40 mm. Laying 0.5, 0.6, 0.7, 0.8 and 0.9 mm thick is issued.
5. Remove a measuring disk and a flange. |

|
186 — the Lock ring
187 — the Internal disk
188, 189 — the External disk |
|
|
|
|
1. Measure a gap of "S". The nominal rate of a gap of a brake of the raising transfer lies within the range of 0.5-1.1 mm. Adjust it if it is necessary, by means of laying of a lock ring (186). Laying 2.0, 2.5 and 3.0 mm thick is issued.
2. Establish a back cover of the transmission. |
