Removal, installation and check of components of a brake of BS of raising transfer and KS coupling

Removal

Design of a brake of BS of raising transfer and KS coupling

86 — the Target 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 raising transfer
187 — the Internal disk
188, 189 — External disks
191 — Kulachkovaya a spring
192 — the Piston of a brake of raising transfer
195 — Dempfernaya a spring


 PERFORMANCE ORDER

1. Remove a back cover of a transmission.
2. Remove a 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 a target 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 raising transfer (172) with the block of disks.
6. Take the block of disks of a brake of raising transfer from the case, having removed a lock ring (186).
7. Remove a dempferny spring (195). Remove a blocking ring (190) and a kulachkovy spring (191).
8. By means of nippers take the piston of a brake of raising transfer (192) of the case, remove teflon rings (196), and then a persistent washer (173).

Installation

 PERFORMANCE ORDER

1. Before installation of a persistent washer (173) be convinced that the lubricant opening (shooter) is established in the transmission case.
2. Grease both sealing rings of the piston of a brake of raising transfer (192) transmission 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 kulachkovy spring (191), establish a blocking ring (190), establish a dempferny spring (195). Establish disks of a brake of raising transfer individually.
4. Carefully insert a support of coupling of raising transfer (17) into a multidisk brake of raising transfer.
5. Carefully insert a crown gear wheel (170) into a brake of 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 a target shaft (167).

Check of an axial gap between target and intermediate in bulk

 PERFORMANCE ORDER

1. Measure «a» distance from a contact surface of the bearing of a target shaft (86) to an internal ring of the bearing (198) by means of a calliper.
2. Define «b» distance from laying (166) to the roller persistent bearing (169) by a calliper.
3. Adjust an axial gap "with" laying (166), having defined thickness of laying: «a» distance (18.00 mm) - «b» Distance (16.60 mm) = the Difference (1.40 mm) - the Axial gap (0.10 mm) - Thickness of laying (1.30 mm). An axial gap between target and intermediate shaft of 0.10 mm. Laying in thickness 0.1, 0.2 and 0.5 mm are issued.
4. Establish a target shaft (86) and insert a blocking ring (165).

Check of an axial gap between target shaft and a back cover

 PERFORMANCE ORDER

1. Measure «a» distance, 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 calliper.
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 «b» distance between a measuring disk (028) and laying (72).
4. Adjust the axial gap «Е» laying: «a» distance (118.80 mm) - «b» Distance = the Difference (1.90 mm) - the Axial gap «Е» (0.40 mm) = Thickness of laying (1.50 mm). The nominal rate axial люфта between target shaft and a back cover makes 0.40 mm. Laying in thickness 0.5, 0.6, 0.7, 0.8 and 0.9 mm are issued.
5. Remove a measuring disk and a flange.

Gap check in a brake of raising transfer

Gap check in a brake of raising transfer

186 — the Lock ring
187 — the Internal disk
188, 189 — the External disk


 PERFORMANCE ORDER

1. Measure «S» gap. The nominal rate of a gap of a brake of raising transfer lies within a range of 0.5-1.1 mm. Adjust it if it is necessary, by means of laying of a lock ring (186). Laying in thickness 2.0, 2.5 and 3.0 mm are issued.
2. Establish a back cover of a transmission.
