8.1.3. Adjustment of a gap and the closed condition of contacts of the breaker

PERFORMANCE ORDER
1. Unscrew two screws and uncover the distributor of ignition and a distributor rotor.
2. Clear an internal surface of a cover of the distributor of ignition and check its state.
3. If the internal surface of contacts of a cover of the distributor of ignition strongly burned, replace a cover.
4. If on contacts there is an insignificant deposit, using the screw-driver, clear it.
5. Pressing the central coal contact in a cover, check smoothness of its movement and a vystupaniye of contact from a cover which has to be at least 6 mm.
6. Using a screw-driver edge, unclench contacts of the breaker and check their state.
7. If contacts are worn-out, they need to be replaced.
8. If contacts of the breaker are in satisfactory condition or new contacts are come, it is necessary to adjust a gap between contacts with use of an edge of the probe.
9. Mark and remove high-voltage wires from spark plugs, then unscrew spark plugs.
10. At the released emergency brake and the included transfer move the car forward and watch the ignition distributor until the lever of contacts of the breaker is on a ledge of one of four cams of a shaft of the distributor of ignition.
11. An edge of the probe check a gap between contacts of the breaker. When checking a gap the edge of the probe and contacts of the breaker have to be pure and dry.
12. If the gap does not correspond to the required values, weaken the screw fixing a plate of contacts and, moving a plate, establish the required gap. The plate can be moved with the screw-driver inserted between a tag in a plate of the breaker and two adjacent ledges of a basic plate of the distributor of ignition.
13. After installation of a gap of contacts of the breaker fix a plate by the screw and repeatedly measure a gap between contacts.
14. Establish an ignition distributor rotor, a cover, spark plugs and high-voltage wires.

In the presence of the measuring instrument of duration of the closed condition of contacts of the breaker, the most exact method of installation of a gap between contacts of the breaker is a measurement and installation of duration of the closed condition of contacts of the breaker.

The corner of the closed condition of contacts of the breaker is a corner on which the ignition distributor cam turns, so far contacts of the breaker remain closed. Advantage of this method is that any wear of a shaft of the distributor of ignition and contour of cams is considered, and also measurement errors when using the probe are excluded.

PERFORMANCE ORDER
1. For check of duration of the closed condition of contacts of the breaker uncover the distributor of ignition and a rotor.
2. Connect measuring instrument probes to contact (15) and contact - (1) coils of ignition.
3. The assistant has to include ignition and turn a bent shaft of the engine a starter.
4. At this time on the measuring instrument read a corner of the closed condition of contacts. Fluctuation of an arrow of the measuring instrument demonstrates that the bent shaft of the engine is turned insufficiently quickly.
5. In this case unscrew spark plugs and repeat check.
6. If a corner too small, then a gap between contacts too big, and vice versa, if a corner of the closed condition of contacts a big, so gap between contacts small.
7. Adjust a gap between contacts of the breaker.
8. After adjustment of a corner of the closed condition of contacts of the breaker disconnect the measuring instrument and establish a rotor of the distributor and a cover of the distributor of ignition.
9. Check installation of a corner of an advancing of ignition.
