Repair and operation of the car

Characteristic defects of a cover of the distributor

1. Breakage on turrets of wires 2. Cracks 3, 5. Breakdown 4. Erosion of electrodes 6. Wear of a piece of coal

Characteristic defects of the runner

1. Loss of elasticity of a spring 2. Contact corrosion 3. Zadevaniye for a cover 4. Cracks

High-voltage wires of spark plugs should be checked (and if necessary to change) along with replacement of candles.

The simplest way of check consists in survey of wires on the working engine in the darkened garage. At detection of a luminescence (breakdown) of a wire replace. Check a condition of a cover and the runner of the distributor.

PERFORMANCE ORDER

1. Disconnect the battery from weight. 2. For check and cleaning of wires disconnect each wire separately. 3. Disconnect a wire from a candle, holding a tip. 4. Check existence of corrosion on the socket of a tip of a wire and on a candle electrode. Check durability of demountable connection, having dressed a tip of a wire on a candle and having shaken it. At leaky connection draw in contact petals. 5. Wipe wires. Strongly do not bend a wire as the conducting vein can break. At detection of cracks, traces of breakdown and a podgoraniye of a wire replace. 6. Disconnect a wire on a cover of the distributor and check a condition of contacts of wires and sealants. 7. Unscrew fastening screws (or wring out brackets) and uncover the ignition distributor. 8. Wipe a cover absolutely and check existence in and outside of a cover of cracks, traces of superficial breakdown (the thin charred paths), wear, a podgoraniye and weakening of contacts. At detection of such defects replace a cover and the runner.
