Check of linear pressure
The purpose of this dough is check of working conditions of each part by means of measurement of pressure of liquid on lines of pressure of liquid. The following conditions are necessary for implementation of the test of linear pressure:
Liquid of an automatic box has normal working temperature (70-80 ° C/158 – 176°F).
Liquid is filled to demanded level (between marks on щупе "COMPLETELY HEATED-UP" and "NEPROGRETY").
|
|
1 — an opening for check of pressure of liquid
2 — the case pallet |
|
|
- Reliably put on the parking brake and put to wheels the verifying device.
- Attach the device for measurement of pressure of liquid to an opening for check of pressure of liquid in the transmission case. Special tool (A): 09925-37810.
|
|
Having attached the device for check of pressure of liquid, check, that there was no leakage of liquid. |
|
|
1 — the case pallet
2 — an exhaust pipe |
- Press up to the end a brake pedal, include idling of the engine and limiting, and then check pressure of liquid in situation "D" or "R".
|
|
Do not leave the engine to work at speed limit more than 5 seconds. |

Results of check
|
Possible reason
|
|
Linear pressure is higher than standard level in each situation
|
* Faulty valve of a regulator
* Faulty valve of a throttle
* the cable of a throttle of an automatic transmission is not adjusted
|
|
Linear pressure is lower than standard level in each situation
|
* Faulty coupling of raising transfer
* Faulty oil pump
* Faulty valve of a throttle
* Faulty valve of a regulator
* the cable of a throttle of an automatic transmission is not adjusted
|
|
Linear pressure is lower than standard level only in situation "D"
|
* Leakage of liquid from direct coupling
* Faulty coupling of raising transfer
* Leak in a chain of pressure of liquid in situation "D"
|
|
Linear pressure is lower than standard level only in the situation "R"
|
* Leakage of liquid from direct coupling
* Faulty coupling of raising transfer
* Leakage of liquid from a backing brake
* Leak in a chain of pressure of liquid in the situation "R"
