For performance of this operation use a measuring instrument of a compression 09915—64510. Check up a compression in a following order:
- Warm up the engine to temperature of normal work of the engine (temperature of a cooling liquid 80—90 °);
- Stop the engine, remove wires of a high voltage and turn out spark plugs
- Disconnect a socket of the optical gauge of the distributor of ignition;
- Establish a measuring instrument of a compression 09915—64510 in an aperture for candle installation;
- Translate the gear change lever in neutral position (facilitate engine start-up), press against the stop a pedal of an accelerator for full opening throttle заслонки;
- Starter turn a cranked shaft of the engine and fix the greatest value of pressure on a compression measuring instrument.
The difference of measured values between cylinders should be no more than 98,06 кПа
. At check of a compression connection between an aperture for a spark plug
and a compression measuring instrument should be absolutely tight.
After check remove a measuring instrument and establish earlier removed details.
Check of pressure of oil
For performance of this operation use a measuring instrument of pressure of oil 09915—77310.
Before to check up pressure of oil, execute the below-mentioned:
- Check up level of oil and add it if it is necessary;
- At engine oil deterioration, at разжижении oils or at change of colour of oil replace it;
- Check up all possible leaks and make repair of faulty details.
Check up pressure of oil in a following order:
Fig. 3.3. Check of pressure of oil: 1 — a measuring instrument of pressure of oil 09915—77310; 2 — the gauge of pressure of oil
- Turn out the gauge of pressure of oil 1 (fig. 3.3
) from the block of cylinders;
- Instead of the gauge of pressure of oil screw a measuring instrument of pressure of oil 09915—77310;
- Start up the engine, warm up it to temperature of normal work of the engine;
- Increase frequency of rotation of a cranked shaft to 2000 mines-1 and fix value of pressure of oil.
After check wind a carving of the gauge of pressure of oil with a thread and tighten the gauge the moment 12—16 Н·м. Start up the engine and check up the gauge of pressure of oil on absence of leak.
