•
NEVER carry out works on the tractor
electrical circuits with the diesel-engine
running.
•
DO NOT check electrical circuits and
components of the electrical equipment
for operational readiness by «spark-
ing» (by short-circuiting).
•
Whenever the alternator is to be installed
on, or removed from, the machine, dis-
connect the storage battery from the
«frame ground».observe the correct po-
larity when connecting the tractor storage
battery or when using an external battery
to start-up the diesel-engine. Connect
plus to plus and minus to minus.
Adjustment of an alternator equipped with
a seasonal voltage regulation is to be
done by means of adjusting screw 1 (see
Fig. 66), by setting it to the «
Л» (summer)
position when it is warm or to the «3»
(winter) position
— in cold season.
Check of Assembly Units of the Diesel-
Engine
Д-243 Starting Arrangement
The Starter.
When the tractor is in ser-
vice, keep the starter clean, regularly
check the reliability of its attachment, the
condition of terminals; dirt and loose fix-
ing cannot be tolerated. Also, check the
starter blush assembly; to do this, un-
screw screws (1) (see Fig. 67) and re-
move protective shroud (2) of the starter.
Check the condition of commutator, brush
fittings, brushes in brush-holders (3) for
easy movement and the pressure of
springs (4) upon the brushes (5) of the
starter. The commutator working surface
should be clean.
The brush pressure: 750-1000 gf.
After 2000 hours of tractor operation, as
well as in case of substantial wear or
commutator burns, have the starter sent
to a specialized workshop.
THE ELECTRIC TORCH PRE-HEATER
The electric torch pre-heater does not re-
quire special attention in maintenance.
Just check attachment of the pre-heater,
its wiring and fuel feed tube while in ser-
vice; clean the jet-hole in the fuel-supply
connection bolt.
The instance of energizing of the pre-
heater and the clearance between the
core and the union connector are adjust-
ed at the manufacturing works and do not
require additional adjustment in the field.
