Backlash measurement in gearing of a gear wheel with a flywheel


Before демонтажем from the starter engine it is necessary to execute following checks:

– 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 up 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 the traction relay: to examine and define a condition of the lock and the relay.
– The raised noise of a starter: for normalisation of noise of a starter at engine start-up to execute the following:

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

2) to Eliminate the found out defect.

2а) to Check up serviceability of a flywheel: absence of a bend, traces of strong deterioration etc.

2б) to Start the Engine and to note by means of a 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 have appeared in gearing with a starter gear wheel.

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

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

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

In the absence of standard linings 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 ignition lock are serviceable, to dismantle a starter for the subsequent check.

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

3) the Bottom bolt of a starter.

4) the Nut of fastening of the main cylinder.

5) the Protective guard of the distributor of ignition.

6) the Negative wire of the storage battery.

Diagnostics of malfunctions of the starter shown in raised noise

MALFUNCTION SIGN	THE REASON
Howl a high-pitch tone at прокручи вании the engine a starter (before engine start-up). The engine for is started up normally	The backlash in gearing of a gear wheel and a flywheel wreath is great
Howl a high-pitch tone after start-up of the engine and отпускания the ignition key. The engine is started normally. This constantly or periodically appearing defect is connected by that the returnable spring cannot deduce a gear wheel from gearing with a flywheel wreath	The backlash in gearing of a gear wheel and a flywheel wreath is small. Radial palpation of a wreath of a flywheel does this defect astable
Sharp increase in noise or the sound similar to a siren, after start-up of the engine and before starter deenergizing	Most a plausible reason – malfunction муфты a free wheeling. Replacement муфты often eliminates this defect
Roar or knock at deenergizing of a starter after engine start-up	Most a plausible reason – deformation or infringement of balancing of an anchor of a starter. It is necessary to replace an anchor
