In this father-in-law measure the pressure reduced by the valve, for check of knots of hydraulic system and identification of leakages of oil.
Preparation
PERFORMANCE ORDER
1. Execute the preparation presented in the section "Testing of collaboration of an automatic transmission and the engine on the motionless car"
2. Connect to the engine a tachometer.
3. Connect a manometer of OK201 190 AA0 to the union of check of pressure.
Procedure
PERFORMANCE ORDER
1. Start up the engine.
2. Check frequency of rotation of a cranked shaft of the engine idling and in a selector "R" position.
Technical characteristics:
Frequency of rotation of a cranked shaft of the engine idling: 800±50 mines-1 Installation of a corner of an advancing of ignition (to the top dead point): 10±1 ° (Contact of TEN of the diagnostic socket is earthed)
3. Consider value of the reduced pressure idling in a position of "R".
Normal value of the pressure reduced by the valve: 360–400 kPas
4. Screw a new stopper with a square head in an opening for the union of check of pressure.
Inhaling moment: 50–100 N • m
Assessment of results of check of pressure of the transmission liquid reduced by the valve
