Long 360 Series User Manual

INSTALLATION ON THE TRACTOR
Install the alternator on a rigid bracket on the
tractor and attach the big projection of the end
shield to this bracket. The small projection
should be attached to a flange that is used for
belt adjusting.
CHECK AT ASSEMBLY:
1. Belt pulley drive surface for dents and
cracks. Such damaged surfaces may lead to
premature wear of the belts.
2. The crankshaft belt pulley, water pump belt
pulley and alternator belt pulley must be in
line.
3. The three aforementioned belt pulleys must
not have radial or axial out-of-true runs.
4. The electric connections must be tight in
order to
protect the electric circuit from high
resistance.
When
replacing conductors of the feeding
circuit, make sure that the new conductors
are of the same gauge and length as the
former ones.
When adding new
electrical loads, never con-
nect them to the circuit between alternator
and voltage regulator; otherwise the alter-
nator voltage
will increase and put the ser-
vice
life of current electrical loads and the
battery in danger.
The
contact between battery minus-terminal
and ground must be clean and tight.
The ground connection between engine and
chassis must be good. It may be tested by
means
of voltmeter for continuous current.
Not complying with recommendations set out in
topic 1 and 3, you will cause overloading of the
alternator bearings, causing premature bearing
failure.
OPERATION INSTRUCTIONS
Problems in the system can be caused by:
1. Letting the alternator operate without con-
necting the battery to the alternator plus-
terminal "8". The diode rectifiers may be
destroyed.
2. The alternator and voltage regulator excita-
tion terminal as well as connecting cables
must not be grounded.
3. Do not reverse or ground the voltage
regulator "OF" and plus-terminals. Do not
check alternator operation by letting the
plus-terminal touch a ground.
4. Do not put alternator excitation terminal in
direct connection with the plus-terminal
(voltage
adjustment is cancelled by directly
feeding the alternator field winding).
5. During alternator operation (while engine is
running) never
disconnect alternator, voltage
regulator or battery, or change connections.
Stop the engine and then disconnect the bat·
tery but prior to putting it into operation,
check for proper connections. Then start the
engine.
If this instruction is not complied with and the
battery is still connected when working on the
electrical system, you risk damaging the diodes
or any other components of the electrical system
if the cables happen to touch (only for a tract ion
of a second) other terminals or the ground.
6. Never let the voltage regulator operate
without being grounded to the alternator.
7. Never charge the battery by means of an out·
side source (rectifier, etc.) without first
disconnecting the plus-and minus-cables
which connect the battery terminals to the
rest
of the system.
8. Avoid arc-welding directly onto the electric
equipment without disconnecting the alter·
nator,
from the electric equipment installed
on the tractor.
9. Do not connect the condensers to the alter-
nator or voltage regulator field winding ter-
minal.
10. Do not try to feed the alternator by. directly
feeding the field winding from the plus-
terminal.
11. Do not reverse the battery terminals (this
would damage the diodes).
When checking stator insulation efficiency with
voltage that is higher than 75 V, it is absolutely
necessary to disconnect the diode rectifiers,
otherwise you may destroy them.
Do
not reverse the cable of the OF-terminal with
th81 of the C-terminal, as the voltage regulator
safety fuse would be opened and the contacts
damaged. In this case the voltage regulator must
be replaced.
MAINTENANCE INSTRUCTIONS
1. Periodically check for good contacts.
2. Periodically check (after about every 200
hours operation) belt tension with a pull of
11·151bs. (49 N • 67 N) on the belt section bet-
ween alternator and crankshaft pulley,
deflection must be .04-.06 inches (10-15mm).
