Check of level of oil in a manual box of gear shifting

Visual check of tightness of a transmission

Leak of oil from a transmission is possible in the following places:

– In a junction of a power shaft to a transmission.
– About a masloslivny stopper.
– About a stopper maslozalivny mountains - avalanches.

For definition of a place of leak of oil execute the following actions:

– Clear a transmission case.
– Cover possible places of leaks with a thin layer of chalk or talc.
– Make a trial trip on distance about 30 kilometers.
– Lift the car on rise - a nickname or over a viewing hole and determine an oil leak place by smudges of oil.

Eliminate leak and fill in oil in a transmission.

Oil in RKPP should not be changed.

1 On transmission there is a stopper of a jellied mouth / measurement of oil which should be removed for check of level of oil. If the car is raised to provide access to this stopper, make sure that it is reliably fixed - do not climb under the car standing only on a jack!

For the correct check of level of oil the car has to be fixed exactly.


2 For weakening of a carving stopper of a maslozalivny opening it is necessary to use a key with a face head.
3 Install the car on the elevator in horizontal situation.

4 Unscrew an oil-filling stopper from a transmission which is located on a lateral surface of a transmission.


5 Check oil level. Level of oil has to be at the lower edge of a carving opening. If necessary add oil through an oil-filling opening. The type of oil is specified in the Section "Types of the Applied Greasings and Liquids" of Specifications.
6 Screw up a stopper of an oil-filling opening and tighten it the moment
50 N • m

The case of a transmission can be made of an aluminum or magnesian alloy. If the new carving stopper of an oil-filling opening is established, it has to be picked up for number for the corresponding transmission as traffic jams have various covering. If to use not the corresponding stopper, there can be a contact corrosion.


8 Through some kilometers check, whether there is no liquid leak.
9 If you noticed that transmission demands a frequent dolivka, it can be only because of existence of leaks which should be revealed and eliminated before there are serious troubles.
