Check, removal and installation of candles накаливания

In the presence of difficulties at engine start it is necessary to check up first of all a compression in engine cylinders. If the compression is insufficient, the engine at low temperature is not started, address to Section compression Check.

The block of management DDE is equipped by the memory of malfunctions which is writing down malfunctions, arisen in an electric part of fuel system of a diesel engine. On HUNDRED data containing in memory, can be считаны by means of the special device.


1. Remove covers of the engine and a pressurisation pipe over candles накаливания.

2. Candles накаливания are under soaking up channels.

3. Disconnect a cable to candles накаливания (an arrow on an accompanying illustration).

4. Attach the device for pressure check to positive contact (+) and by turns to each candle накаливания.

5. If the light-emitting diode lights up: the Candle накаливания is perfectly in order. For more exact check it is necessary to measure by the ampermeter current size.

6. If the light-emitting diode does not light up: the Candle накаливания is damaged. Replace it.


1. Remove the inlet pipeline, address to Section Removal and installation of the inlet pipeline

2. Disconnect cables (1) and (2). Turn out candles накаливания and check up visually. Address to an accompanying illustration.


1. Grease a carving of candles накаливания with high-temperature copper paste “CRC”. Screw candles. The moment of an inhaling of 25 Nanometers.

It is not necessary to exceed the specified moment of an inhaling, since. The ring backlash between a heating core and a carving part of a candle can increase.

2. Attach a cable to candles накаливания. A fastening nut tighten the moment of 5 Nanometers.
3. Fix the inlet pipeline to a head of cylinders the moment of 25 Nanometers. All consolidations replace with the new. Support of the case of the oil filter and the system pipeline рециркуляции fix to the inlet pipeline also the moment of 25 Nanometers.
4. Establish to the place of a cover of the engine and a pressurisation pipe.

Candles накаливания with the fused cores

The fused cores of candles накаливания often are a consequence of faulty work of atomizers.

At detection of the damaged candles (marksman) it is necessary to replace them and necessarily to check up work of atomizers.
