7.6. Check and adjustment of a gap between contacts of the breaker
The gap between contacts of the breaker is regulated time in 15 thousand km or is more often if it is necessary (see the section "Diagnostics").
We uncover the distributor, without taking out from it high-voltage wires, and we take a cover aside.
We turn a bent shaft of the engine for a ratchet so that the plastic emphasis a rychazhka of mobile contact appeared at top of a ledge of a cam and the gap between contacts became maximum. Operations on check and adjustment of a gap between contacts of the breaker are for descriptive reasons shown on the removed distributor.
We remove a distributor rotor (see. "Removal of a cover and rotor of the distributor of ignition").
The flat probe we check a gap between contacts of the breaker. The optimum size of a gap - 0,45 mm.
In need of adjustment we weaken the screw-driver two screws of fastening of a plate of motionless contact:
one — from the vacuum regulator of an advancing of ignition...
... and the second — from contact of a wire from the ignition coil.
We insert the screw-driver into a groove of a plate of motionless contact and, shifting a plate, we try to obtain a necessary gap between contacts then we tighten screws of fastening of a plate.
Screws of fastening of a plate of motionless contact of the breaker should not be tightened too strongly not to damage the bearing of a mobile plate of the breaker.
After adjustment of a gap between contacts of the breaker it is necessary to check and if necessary to adjust an ignition advancing corner (see. "Adjustment of the moment of ignition"). For replacement of contact group we disconnect a condenser wire from a contact bolt of fastening of a tip of a wire of the distributor (see. "Dismantling of the distributor of ignition").
Key "on 7" we turn off a nut of a contact bolt...
... we take out a bolt and we remove from it a wire tip.
We unscrew two screws of fastening of a plate of motionless contact...
... also we remove contact group of the breaker.
We establish new kontakny group in the return sequence and we regulate a gap between contacts. We establish a rotor and a cover of the distributor in the return sequence.
