8.1.2. Service of the distributor of ignition

Removal and installation

Removal

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Uncover the distributor assembled VV wires.
  3. Disconnect an electrical wiring and a vacuum hose of the proofreader of ignition from the distributor.
  4. Turn the engine clockwise so that the runner turned a nose towards an arrangement of the plug of a candle wire of the first cylinder. Make sure of combination of distributive tags on the engine.
  5. Mark position of the case of the distributor in relation to a head of cylinders, then give a fixing bolt and remove the distributor. Try to remember in what direction the runner was turned and record its final situation.

Installation

Installation is made upside-down.

 PERFORMANCE ORDER

  1. Check a condition of a sealing ring (rings) of the distributor, replace defective.
  2. If the engine was turned after extraction of the distributor, turn of a bent shaft bring the piston of the first cylinder into the situation close to the provision of VMT of the end of a step of compression, then achieve combination of a tag of VMT of a bent shaft with a zero mark of a distributive scale in a cover of the drive of the gas-distributing mechanism.

If to turn out a spark plug of the first cylinder and to clamp a candle opening a finger, then at approach of the piston to the provision of VMT of the end of a step of compression the distinct feeling of pressure will appear.

  1. If the engine was not turned, install the runner in a starting position (which it reached later from extraction from the engine) and install the distributor in a head of cylinders, trying to obtain combination of landing tags. Screw a fixing bolt.
  2. Connect an electrical wiring and a vacuum hose to the distributor and execute installation of a corner of an advancing of ignition.

  2. Give the remained screws of fastening of the block of the vacuum proofreader. Remove an E-shaped clip and remove the block from the distributor.
  3. Give fixing screws and remove a basis plate from the distributor.
  4. Supporting a driving gear wheel of the distributor, give the screw of fastening of a shaft of a rotor of the sensor of ignition. Take a shaft from the distributor case.
  5. Mark adjusting provisions of springs and small weights of the proofreader of an advancing of ignition.
  6. Disconnect and remove springs.
  7. Remove E-shaped clips and remove the proofreader's small weights.

Cleaning and check of a state

 PERFORMANCE ORDER

  1. Carefully wash out all components, except for electric knots and the block of the vacuum proofreader of an advancing of ignition, in suitable solvent.
  2. Estimate degree of wear of the lower shaft and the case of the distributor. In case of need make replacement.
  3. Check a cam, small weights and springs for existence of signs of wear and damages. In case of need make replacement.
  4. Check a basis plate for wear and damages. In case of need replace.
  5. On models of 4.2 l check contacts of the breaker for existence of signs of wear and cavities. In case of need make replacement.

At installation of new assembly of contacts of the breaker surely replace also the condenser.

  1. Check a distributor cover, the runner and the screen of the limiter of turns for existence of cracks, coal paths, progar and traces of corrosion of plugs.
  2. Estimate degree of wear of the central piece of coal. Measure the size of its vystupaniye.
  3. Check the vacuum proofreader's block for existence of signs of leaks through a diaphragm for what press on connecting draft, press a finger to the soaking-up tube, then release draft. Depression under a finger has to keep within at least 30 seconds.
  4. Check a condition of sealing rings, replace defective.
  5. Estimate degree of wear of a driving gear wheel.
