3.6. Replacement of motive oil and oil filter
|
|
The long contact of skin with the fulfilled motive oil is quite dangerous. Use protective cream or put on rubber gloves during the procedures described below. |
|
|
Frequent replacement of motive oil is the main preventive procedure of service, to the available amateur mechanic. Eventually oil is subject to fluidifying and pollution that leads to premature wear of the engine.
|
Sinking of motive oil
|
|
Motive oil can be pumped out by means of the probe through the directing probe tube. |
|
|
- Warm up the engine up to the working temperature of cooling liquid.
- The car also establish to Poddomkratta it on props, or tire out on a viewing hole.
|
|
- Substitute under a drain stopper capacity about 6 l for collecting the fulfilled oil.
|
- Turn out a drain stopper and let's oil flow down completely.
|
|
Do not burn a hand with the warmed following oil! |
- Check a condition of the fulfilled oil. If in it there are at a large number a metal shaving and products of wear, it indicates existence of zadir, for example, in bearings of a bent shaft and conrod bearings. For an exception of damages after the made repairs it is necessary to clear carefully oil channels and hoses, and also, at the corresponding complete set, to replace the oil cooler.

Replacement of an oil filter
Replacement of an oil filter of the diesel engine
|
|
- Turn out an oil filter from a flange (see an illustration). For this purpose it is possible to use special adaptation or a tape key. It is also possible to insert the sharp screw-driver sideways into the filter, at the same time oil therefore in advance substitute capacity for collecting oil under the filter will begin to follow from the filter.
|
|
On diesel engines the replaceable element of an oil filter is in the special case and for its replacement it is necessary to turn out a case cover. At installation of a cover use a new sealing ring. |
- Wipe a surface of an oil filter and its flange on the block of cylinders and remove sealing laying if it remained on a flange.
- Grease sealing laying of a new oil filter with pure motive oil.
- Screw a new oil filter by hand. After laying will lie down to a flange on the block of cylinders, tighten the filter on three quarters of a turn. Pay attention to the remarks given on the filter case.

Filling of the engine with oil
|
|
When replacing it is necessary to use oil of identical type and, whenever possible, identical brand. It is for this purpose recommended to fix at each replacement of oil on the engine a label with the indication of brand and viscosity of oil. Motive oils of identical type and identical brands, but different viscosity can fill in during appropriate time of year. |
|
|
- Screw a carving stopper of a drain opening and tighten it with effort of 25 N • m.
- Uncover a jellied mouth and fill in motive oil approximately on half of liter less, than it is specified (see the Section Check of Levels of Liquids, control of leaks).
- Start the engine and let's it work idling, having checked existence of leak of motive oil meanwhile, paying special attention to the filter and a drain stopper.
- Wait for 5 minutes, then check the level of oil and if necessary modify it.
- Make a trial trip on the car and again check a drain stopper and an oil filter for leaks. If necessary, carefully bring up them. Double-check oil level, if necessary modify it.
