8.2.3. Diagnostics of leak of operational liquids

GENERAL INFORMATION

The majority of leaks is defined visually, and repair usually consists in replacement of sealing rings or laying. In case of difficulties with detection of a place of leak use the following reception:

PERFORMANCE ORDER
1. Define liquid type. Be convinced that it is transmission liquid, but not engine oil or brake fluid (transmission liquid has dark red color).
2. Try to define a leak place. Make a control trip, and then enclose a big sheet of paper under the car. In 1–2 minutes it is possible to determine a leak place by liquid drops on paper.
3. Carry out a careful visual inspection of a suspicious detail and surfaces round it. Pay attention to laying.
4. If leak is still not found, carefully clear the suspected surface by means of solvent and dry up it.
5. Make a control trip on the car, and after a trip double-check a detail.
6. After definition of a place of leak it is necessary to define its reason. If laying is replaced, but the sealing flange is deformed, new laying will not stop leak. It is necessary to level a flange.

Leaks in laying

PERFORMANCE ORDER
1. Periodically check the pallet. Be convinced that all bolts on a place and are tightened, laying in a good shape, and the pallet equal.
2. If laying of the pallet proceeds, can be, too high level of liquid or its pressure, the ventilation opening is polluted, pallet bolts are not tightened, the sealing flange of the pallet and the condensing transmission case surface is deformed, laying or a case of a transmission is damaged can have cracks or a time.

Leakages of sealing rings

PERFORMANCE ORDER
1. Too high level of liquid and its pressure can be the cause of course of sealing rings of a transmission, the air vent is polluted, the nest for a sealing ring or a sealing ring is damaged.
2. Check that consolidation of a tube of the masloizmeritelny probe is in a good shape and the tube is established correctly. Periodically check a surface about a speedometer drive gear wheel. If leak of transmission liquid is noticed, check, whether the sealing ring is damaged.

Leaks in a case

If on the case there are leaks, the case can have a time and it needs to be repaired or replaced.

Liquid acts from an air vent or a tube for the probe

If the specified signs are noticed, can be, the transmission is crowded, and cooling liquid got to transmission liquid.
