Actions
|
Pressure in the pipeline very low (or high).
Pressure in the pipeline concern standard pressure трансмиссионной liquids 2, 3, 4, 5, 6, 7 and 8, resulted in the table |
1. The oil filter is polluted
2. Wrong adjustment of pressure by the regulating valve
3. The regulator distributor is polluted
4. There is a backlash of the case of valves
5. The inappropriate pressure created by the oil pump |
1. Visually examine the oil filter and, if necessary, replace it.
2. Check up pressure in the pipeline by criterion 2 (Kickdown):
– If pressure does not correspond demanded, adjust pressure in the pipeline and, if necessary, replace the case of valves
3. Check up functioning of the regulating valve and, if necessary, replace the case of valves
4. Tighten bolts of fastening of the case of valves and an adjusting bolt
5. Check up an axial backlash of a gear wheel of the oil pump and, if necessary, replace the oil pump |
|
Inappropriate reduction of pressure |
1. Inappropriate pressure in the pipeline
2. A filter contamination (L-shaped type)
3. Wrong adjustment of reduction of pressure
4. Wrong adjustment of reduction of pressure
5. Jamming редукционного the valve
6. There is a backlash of the case of valves |
1. Check up pressure by criterion 2:
– If pressure does not correspond demanded, item 1 see
2. Disassemble the case of valves, check up a condition of the filter and, if necessary, replace it
3. Check up pressure by criterion 1:
If pressure does not correspond demanded, repair or replace the case of valves
4. Check up functioning of the regulating valve and, if necessary, replace the case of valves
5. Tighten bolts of fastening of the case of valves and an adjusting bolt |
|
Inappropriate pressure of a brake kickdown |
1. The D-ring, a sealing ring, the plug or сервопоршень kickdown is damaged
2. There is a backlash of the case of valves
3. Functional failure of the case of valves |
1. Remove сервопоршень kickdown and check up a condition of a sealing ring and a D-ring. In the presence of scratches replace a D-ring or a sealing ring
2. Tighten bolts of fastening of the case of valves and an adjusting bolt
3. Replace the case of valves |
|
Inappropriate pressure of forward coupling |
1. The D-ring, the plug or сервопоршень kickdown is damaged
2. There is a backlash of the case of valves
3. The case of valves is damaged
4. Deterioration of the forward piston of coupling or a clamp, D-ring damage
5. The lining of the oil pump or a sealing ring is damaged |
1. Remove сервопоршень kickdown and check up a condition of a sealing ring. In the presence of scratches replace a sealing ring or a D-ring
2. Tighten bolts of fastening of the case of valves and an adjusting bolt
3. Replace the case of valves
4. Disassemble a transmission and check up deterioration of the piston of forward coupling, an internal circle of a clamp or D-ring damage. In the presence of deterioration and damages replace corresponding elements |
|
Inappropriate pressure of coupling of the main transfer |
1. The D-ring, a sealing ring or a sealing ring of the pipeline is damaged
2. There is a backlash of the case of valves
3. The case of valves is damaged |
1. Disassemble coupling of the main transfer and check up a D-ring condition, a piston ring, a sealing ring of a clamp etc. In the presence of scratches replace corresponding elements
2. Tighten bolts of fastening of the case of valves and an adjusting bolt an adjusting bolt
3. Replace the case of valves |
|
Low pressure of a brake of low transfers and backing transfer |
1. Consolidation between the case of valves and a transmission is damaged
2. There is a backlash of the case of valves
3. The case of valves is damaged
4. The sealing ring of a brake of low transfers and transfer of a backing or a sealing ring of a clamp is damaged |
1. Remove the case of valves, check up a condition of consolidation and, if necessary, replace it
2. Tighten bolts of fastening of the case of valves and an adjusting bolt
3. Replace the case of valves
4. Disassemble a transmission, check up a condition of a sealing ring and, if necessary, replace it |
|
Inappropriate pressure of the hydrotransformer |
1. Jamming of the distributor with an electromagnetic drive of management of shock-absorber coupling (DCCSV) or the valve of management of shock-absorber coupling
2. A contamination or leak of an oil radiator and-or lines
3. The sealing ring of an entrance shaft is damaged
4. The hydrotransformer is damaged |
1. Check up system action муфты the shock-absorber and DCCSV
2. Repair or replace a radiator and-or lines
3. Disassemble a transmission, check up a condition of a sealing ring and, if necessary, replace it
4. Replace the hydrotransformer |
|
Inappropriate pressure of coupling of transfer of a backing |
1. The D-ring, a sealing ring or a sealing ring of coupling of transfer of a backing is damaged
2. There is a backlash of the case of valves
3. The case of valves Possibly, same reason, as a cause of infringement of pressure is damaged by management of shock-absorber coupling |
1. Disassemble coupling of the main transfer and check up a condition of a D-ring of the piston, a sealing ring of a clamp etc. In the presence of scratches replace corresponding elements
2. Tighten bolts of fastening of the case of valves and an adjusting bolt
3. Replace the case of valves Possibly, same method of elimination, as elimination of a cause of infringement of pressure by management by shock-absorber coupling |
