Examination
1 - vacuum modulating pressure regulator; 2 - screw for adjusting the modulating pressure; 3 - vacuum control socket; 4 - overload switch; 5 - modulating pressure control socket; 6 - pressure control socket in the centrifugal regulator; 7 - working pressure control socket; 8 - control pressure rod
1. Remove plug 5 and connect an oil pressure gauge.
2. Disconnect the hose from the vacuum regulator.
3. Put the selector lever in position «D» and at a speed of 50 km/h read the pressure gauge.
4. In case of deviation from the norm (see Design and specifications) adjust the modulating pressure.
Adjustment
1. Remove the cap from the vacuum regulator.
2. Remove the stopper from the slots.
3. Turning the adjusting screw with the stopper, set the normal value, and one turn of the adjusting screw changes the pressure by about 0.4 kg / cm 2.
4. After adjustment, insert the stopper into the slots and put the cap on the vacuum regulator.
5. Check modulating pressure and correct if necessary.
6. Connect the hose to the vacuum regulator.
