Coupling of the raising transfer


Design of coupling of the raising transfer

172 — the Support of multidisk coupling
174, 179 — Lock rings
180 — the Spring disk
181, 185 — Radial epiploons

182 — Pruzhina
183 — the Piston
184 — the Sealing ring
02 — the Stripper


1. Remove a lock ring (174) from a support of multidisk coupling (172).
2. Remove the block of disks (176) - (178) and a disk spring (175).
3. Establish a stripper (020) on a spring plate (180) so that the lock ring (179) opened.
4. Remove a spring plate (180), a spring (182), a radial epiploon (181).
5. Take the piston (183) from an external support of coupling (172).

Assembly and measurement of a gap in coupling of the raising transfer

Coupling assembled

172 — the Support of multidisk coupling
179 — the Lock ring
180 — the Spring disk
181, 185 — the Radial epiploon

182 — Pruzhina
183 — the Piston
184 — the Sealing ring


1. Insert the plug (023) into a support of coupling (172). Check a radial epiploon (185) and a sealing ring (184) for lack of wear, and if it is necessary, replace and grease them with transmission liquid. At assembly be convinced that edges of epiploons (181) and (183) are located up.
2. Insert the piston (183).
3. Remove the plug (023).
4. Insert everything 18 or 19 springs (182) into a guide of the piston (183).
5. Insert the plug (024) into a support of coupling (172).
6. Grease an epiploon (131) with transmission liquid and establish on a spring plate (180).
7. Fix a spring plate (180).
8. Establish a lock ring (179) on a spring plate. Establish and fix a stripper (020). Insert a lock ring (179). Be convinced of correctness of installation.

Order of installation of clutch plates

174 — the Lock ring
176 — the Disk spring
178 — Internal disks
177, 178 — External disks


1. Disconnect and remove a stripper (020). Establish clutch plates in the order specified on an accompanying illustration and insert in turn. Before installation put new disks in transmission liquid approximately for 1 hour.
2. Remove the plug (024).
3. Measure a gap of "S" and adjust it a lock ring (174) if it is necessary. Thickness of a lock ring of 2.0, 2.5, 3.0 and 3.5 mm.
