Problems connected with a belt of drive gas distribution

Problems with start-up of the engine, connected with a belt of drive gas distribution


Frequently, one of the reasons of the complicated start-up of the engine is sharp increase of the effort demanded for cranking of a cranked shaft. This problem can be caused by malfunction of many units. We shall pay attention on possible of a problem with a belt of a drive of the gas-distributive mechanism.

Check of the effort necessary for cranking of the engine
Sharp increase of effort cranking the engine can be caused by destruction and jamming of any bearing or the unit (the compressor of the conditioner, the hydraulic booster, the air compressor). From bearings bearings of bypass and tension rollers of a gear belt gas distribution, bearings of the water pump, the bearing of a tension roller of the compressor of the conditioner more often collapse. Destruction of bearings is promoted by an excessive tension of belts and absence of greasing in them. Any petrol engine can be turned on the sly if to pull two hands for drivebelts (a pomp, the generator, etc.).

Check of a belt gas distribution
It, perhaps, the most simple work. Take off a cover ignition distributor and turn a key of ignition in position "start". Naturally, central wire going from the coil of ignition, it is necessary to earth. If it is not present, as, for example, at engines 1S, 3A, etc. where the coil of ignition and ignition distributor are in one case it is necessary to separate any socket of the plait going in ignition distributor. If at cranking the engine "breaker" does not rotate, most likely, it is required to replace a gear belt, but before try to turn fingers "breaker".
If it will be possible, the belt can be and the whole, and the reason that cut off a pin in a drive ignition distributor (one such case on engine SA-18) as a result, for example, destructions of the automatic device of a centrifugal advancing of ignition is noted. It is generally better, if you connect a stroboscope and at rotation of the engine evidently will observe on labels on a flywheel the moment of submission of a spark. In this case at you will be hundred percent of confidence of correctness of installation of a belt gas distribution.
