The angle of the closed state of the contacts (USSC) of the car VAZ-2105 can to determine the amount of movement of the toothed belt camshaft. For this is necessary to remove toothed belt guard and attaching parallel contacts breaker control lamp, crank when the ignition is cranked the shaft at an angle to "control print light went off. Then on the belt, on the contrary any the movable point (for example, one of the marks on the lid of the gears) should do marker visible line, then rotate the crankshaft until turn on the lamp.
Then measure with a ruler how moved the strap relative to the same point. If the value will fit into 62±3.4 mm, this corresponds to the desired USSC, that is 55±3°. In the case of extreme deviations it is necessary to adjust the gap between contacts and repeat the measurement.
Fixture length measurement of USSC: 1 - hose; 2 - arrow; 3 - screw; 4 - the ignition distributor
USSC can also be determined with the arrow pointer. Hand cut tin cans and installed under the screw rotor breaker (runner) or made of wire and is attached to the rotor clay. In the role of "scale" will be cut along a segment of rubber or plastic hose with an outer diameter of 4-5 mm For "Lada" its length is 35 mm, which corresponds to USSC 55°.
"Scale" is put on the side of the distributor housing and is pushed when the arrow the beginning of the reference.
