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

Visual check of tightness of a transmission

Leaks of oil from a transmission are possible in following places:

– In a power shaft junction to a transmission.
– Nearby маслосливной stoppers.
– About a stopper маслозаливной mountains - ловины.

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

– Clear картер transmissions.
– Possible places of leaks cover with a thin layer of a chalk or talc.
– Make a trial trip on distance about 30 kilometres.
– Lift the car on lifting - нике or over a viewing hole and on oil smudges define a place of leak of oil.

Eliminate leak and fill in oil in a transmission.

In РКПП it is not necessary to change oil.

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 get under the car standing only on a jack!

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


2 For easing of a carving stopper маслозаливного apertures it is necessary to use a key with a face head.
3 Establish the car on the lift in horizontal position.

4 Unscrew маслоналивную a stopper from a transmission which is located on a lateral surface of a transmission.


5 Check up oil level. Oil level should be at the bottom edge of a carving aperture. If necessary add oil through маслоналивное an aperture. The oil type is specified in Section “Types of applied greasings and liquids” Specifications.
6 Screw up a stopper маслоналивного apertures and tighten its moment
50 Н•м

Carter of a transmission can be made of an aluminium or magnesian alloy. If the new carving stopper маслоналивного apertures it should be picked up for number for a corresponding transmission as stoppers have a various covering is established. If to use not corresponding stopper there can be a contact corrosion.


8 Through some kilometres check up, whether there are no liquid leaks.
9 If you have noticed that transmission demands frequent доливки, it can be only because of presence of leaks which should be revealed and eliminated before there will be serious troubles.
