Repair and car operation

– check of serviceability of system of start-up of the engine.
– check of serviceability of the storage battery.
– check of serviceability of electric conducting: to check integrity of wires and reliability of electric connections of the battery, the lock of ignition, a starter, including a "mass" wire. If necessary to clear contacts and to tighten fastenings of wires.
– check of serviceability of the lock of ignition and traction relay: to examine and define a lock and relay condition.
– the increased noise of a starter: for normalization of noise of a starter at start-up of the engine to execute the following:

1) By the table of diagnostics to define the reason of the increased noise.

2) To eliminate the found defect.

2а) to Check serviceability of a flywheel: lack of a bend, traces of strong wear etc.

2б) to Start the Engine and to note by means of chalk or coal of top of teeths of a wreath of a flywheel with the greatest radial palpation. To switch off the Engine and to turn a cranked shaft so that noted teeths of a wreath appeared in gearing with a starter gear wheel.

2в) to Disconnect a negative wire of the battery.

2г) to Check a gap between a gear wheel and a gear wreath of a flywheel by means of wire щупа in diameter of 0,5 mm, fig. Gap measurement in gear wheel gearing with a flywheel. For the correct definition of a gap it is necessary to center gear wheel tooth between teeths of a wreath and to insert щуп between top of tooth of a gear wheel and a wreath hollow. If a gap less demanded to remove a starter from a flywheel on necessary distance.

2д) If the gap much more exceeds 0,5 mm and makes about 1,5 mm, to move up a starter to a flywheel. The raised gap can cause breakage of teeths of a flywheel. For reduction of a gap it is necessary to adjust thickness of laying only on an external support of a starter. Laying in thickness of 0,4 mm, located in this place, corresponds to change of a gap in gearing about 0,3 mm.

In the absence of standard laying of a starter it is possible to use flat washers or other similar details.

Check of serviceability of a starter: if the battery, electric conducting and the lock of ignition are serviceable, to dismantle a starter for the subsequent check.

It is forbidden to include a starter more, than for 30 seconds continuously. Between inclusions of a starter it is necessary to maintain a pause not less than 2 minutes for its cooling. The starter overheat because of long and continuous work can put it out of action. Details of a starter do not demand some greasing in use, except cases of complete dismantling of a starter.

3) Bottom bolt of a starter.

4) Nut of fastening of the main cylinder.

5) Protective guard of the distributor of ignition.

6) Negative wire of the storage battery.

Diagnostics of malfunctions of the starter which is showing in increased noise

MALFUNCTION SIGN	REASON
Howl a high-pitch tone at прокручи engine vaniya a starter (before engine start-up). The engine for is started up normally	The gap in gearing of a gear wheel and a flywheel wreath is great
Howl a high-pitch tone after start-up of the engine and an ignition key otpuskaniye. The engine is started normally. This constantly or periodically appearing defect is connected with that the returnable spring cannot deduce a gear wheel from gearing with a flywheel wreath	The gap in gearing of a gear wheel and a flywheel wreath is small. Radial palpation of a wreath of a flywheel does this defect unstable
Sharp increase in noise or the sound similar to a siren, after start-up of the engine and before starter switching off	The most probable cause – malfunction of the coupling of a free wheeling. coupling replacement often eliminates this defect
Roar or knock at starter switching off after engine start-up	The most probable cause – deformation or violation of balancing of an anchor of a starter. It is necessary to replace an anchor
