1.9 Serial number identification and location
The generator serial number identifies your particular unit and is important when ordering parts and
accessories. A serial number bar code sticker is placed on the generator, on the shipping carton, and on the
inside cover of the owner’s manual. Additionally, it is engraved onto a metal serial number tag riveted to the
generator.
The serial number for the KDE5000T is located on the
chassis to the left of the battery and below the oil drain plug.
The serial number for the KDE5000E can be found on the
left side of the generator frame below the control panel.

2. SERVICE INFORMATION
2.1 The importance of proper servicing
Proper servicing is essential to the safety of the operator and the reliability of the generator. Any error or oversight
made by the technician while servicing can easily result in faulty operation and/or damage to the equipment or
injury to the operator.
!
Warning
Improper servicing can cause an unsafe condition that can lead to serious injury or death.
Follow the procedures and precautions in this shop manual carefully.
Some of the most important precautions are stated below.
2.2 Important safety precautions
Be sure you have a clear understanding of all basic shop safety practices and that you are wearing
appropriate clothing and safety equipment. When performing maintenance or repairs, be especially
careful of the following:
• Read the instructions before you begin, and be sure you have the tools and skills required to perform the tasks
safely.
• Be sure that the engine is off before you begin any maintenance or repairs. This will reduce the
possibility of several hazards:
- Carbon monoxide poisoning from engine exhaust.
- Burns from hot parts.
- Injury from moving parts.
• Do not run the engine unless the instructions tell you to do so. Keep your hands and
clothing away from rotating parts.
• To reduce the possibility of fire or explosion, exercise extreme caution when
working around gasoline. Use only a nonflammable solvent, not gasoline, to clean parts.
Keep cigarettes, sparks and flames away from all fuel-related parts.
2.3 Service rules
• Use genuine KIPOR or KIPOR-recommended parts and lubricants or their equivalents. Parts that do not meet
Kipor’s design specifications may damage the engine.
• Use the special tools designed for the product.
• Always install new gaskets, O-rings, etc. when reassembling components.
• Clean parts in cleaning solvent upon disassembly. Lubricate any sliding surfaces before reassembly. After
reassembly, check all parts for proper installation and operation.
• Many screws used in this machine are self-tapping. Be aware that cross-threading or over tightening these
screws will strip the threads and ruin the hole.
11
•
Use only metric tools when servicing this engine. Metric bolts, nuts and screws are not interchangeable
with non-metric fasteners. The use of incorrect tools and fasteners will damage the engine.
2.4 Electrical precautions
•
Hold the connector body to disconnect the connector. Do not disconnect by pulling the wire harness. To
disconnect the locking connector, be sure to unlock first, and then disconnect.
•
Check the connector terminals for bend, excessive extrusion, missing terminals, or other abnormalities
before connecting the connector.
•
To connect, insert the connector as far as it goes. If the connector is a locking type, be sure that it is
locked securely.
•
Check the connector cover for breakage and check whether the connector female terminal is not opened
excessively. Then, connect the connector securely. Check the connector terminal for rust. Remove the
rust using an emery paper or equivalent material before connecting the connector.
•
Set the harness clips in the specified places of the frame securely, and secure the wire harnesses.
•
Clamp the cables securely.
•
Clamp the wire harnesses securely so that they do not interfere with the rotating parts, moving parts and
hot parts.
•
Route and connect the wire harnesses properly. Be sure that the harnesses are not slack, twisted or
pulled overly taut.
•
Route the wire harnesses properly so that they do not contact sharp edges and corners and the end of the
bolts and screws on the body.
•
If a wire harness must contact the end of the bolts or screws or sharp edges and corners, protect the
contact part of the harness with a loom or by winding with electrical insulating tape. If the wire harness has a
grommet, set the grommet securely.
•
Take care not to pinch the wire harnesses during installation of a part. If a wire harness has damaged
insulation, repair by winding with electrical insulating tape.
•
When using an electrical tester like a volt/ohm meter or clamp on meter, read the manufacturer’s
operating instructions carefully before operating the tester. Be sure that the tester battery is fully charged and
the meter is functioning properly

Remedy:
The fuel supply is insufficient
Adjust or disassemble and clean
Injection pump or injector is defective
Check or replace
Generator has an overload or short Repair the fault
circuit fault
Engine governor spring is faulty
Replace the springs
Valves out of adjustment
Adjust valves
(3)The generator produces no AC power or the voltage is abnormal or fluctuating.
Fault:
Gauge panel of
generating set
Alternator fault
Remedy:
1. Circuit breaker fails to
function
Remove it and check for open circuit. The
resistance reading should be “0”
2. The wiring of gauge
panel is loose
Check for continuity in the wiring harness.
3. The connection of
receptacle is loose or
contact broken.
Check or replace receptacle
1. The stator leads are not
properly connected
Check the wiring harness
2.The four point output
terminal is cracked
Check or replace terminal
3. Short, open, or
grounded stator windings
Check resistance values of all windings.
Replace stator if shorted, open or grounded
4 Loss of magnetism in
main rotor
Check AVR
5. Short, open, or
grounded rotor windings
Check resistance values and replace rotor as
necessary
6. Carbon brush assembly Check resistance value at slip rings. Check
defective
brushes for wear, weak spring tension
7. Insulation resistance of
generator is too low.
16
Check insulation resistance of stator and rotor.
Replace stator and rotor as necessary.
(3) AVR fault
Fault:
Remedy:
1. Voltage cannot be regulated
Adjust or replace AVR
2. Generator set automatically stopped after
loading, current setting incorrect
Check output voltage, adjust or replace AVR
3. Electric component failed
Replace AVR
4. Sampling signal but no exciting output
Check exciting output voltage of AVR. Adjust and or replace.
5. The voltage cannot be established because of
insufficient residual voltage in the stator
Check that the voltage of main winding is 6 V or more with
AVR disconnected.
6. Power loss is increased because of higher
voltage output of the secondary winding
Check that the voltage of secondary winding should not be
greater than 140 VAC
7. The voltage deviation of zero load and full load is
too large.
- Check AVR and stator.
- This may be caused by operating the generator in too high
of an ambient temperature.
8. Overload shutdown caused by high power
factor loading
Check inductive loads for low power factor and adjust size
of load to rated power*
Divide the appliance current draw by its power factor to determine the effect on the generator. A device
pulling 40 amps with a power factor of .85 places a 47 amp draw on the generator (40/.85). In this example, the
generator would experience an overload shutdown.
(4) Display panel fault
Fault:
Remedy:
1. No display on screen.
Check 12V power supply of the generator and check wiring. If
OK, replace the display unit

3.5 Generator
3.5.1 Check
(1)
Front end cover: check for cracks
(2)
Generator fan: check for missing or chipped blades
(3)
Rotor: make sure it is clean and free of engine contaminants like grease and oil.
Normal measured resistance should comply with section 2.5. The copper windings should be clean and
bright with no trace of corrosion. Black or cracked windings indicate a short necessitating replacement.
(4)
Clip ring: It should be smooth without any defect or distortion. The semicircle of the center boss
should be clear. In case of distortion replace the clip ring
(5)
Through bolt: tightening torque is 37-41 Lbf (50-55 N.m). This is essential to ensure the generator
won’t be damaged by scrubbing of the rotor and stator.
(6)
Stator: Check the external enamel covered wire for defects after disassembly and reassembly. Do not
contact the copper windings with ground or pieces of sharp metal to prevent scuffing.
Stator checks: Check the resistance of the main winding, secondary winding, sampling winding and
battery charge winding. The stator must be changed if any resistance reading is outside the parameters.
However, insure that there is continuity in the harness before proceeding with a stator change.
(a) Main winding: Check resistance on the four position terminal board. You should have 0.75 to 0.85 Ω
between L1 and L2 and R1 and R2. Check the “zero” on your meter before checking these values.
(b) Secondary or sub winding: Locate the 4 pin connector at the top of the stator. Check the resistance
between the two blue green wires. The nominal value is 2.5 Ω.
(c) Sampling winding: On the same 4 pin connector, check the resistance between the two yellow wires.
The value is 0.5 Ω. Check the “zero” on your meter before checking these values.
(d) Charge winding: Find the 4 pin connector at the top of the stator. There are only two pins. The
resistance value should be 2.5 Ω.
(7) Carbon brush: There should be no open circuit between lug and pole of the carbon brush and no short circuit
between the two poles. Check the brushes for wear. If the brush wear is uneven or the length is less than 0.12
in. (3mm) replace.
(8) Rear end cover: check for cracking.
3.5.2 Disassembly
(1)
Open the rear end cover for open frame generator. Remove the cabinet, cooling plate, left and right
side plates, and muffler for TA model.
(2) Remove the alternator assembly with the harness. With the KDE5000T, you must remove the air
induction hood to get to the harness.
(3)
Remove 4 - M6 x 175M bolts from the rear end cover.
(4)
Remove the stator.
(5)
Secure the rotor to prevent it from dropping and remove the 10mm flange bolt.
(6)
Remove the rotor with a puller.
27
3.5.3 Rotor Installation
Caution: Remove any dust and oil pollution from the crankshaft and rotor. Check the resistance of the new part
before installation.
1)
Insert the semicircle clip ring into key groove.
2)
Install the rotor on the crankshaft.
(3)
Secure the rotor with a strap wrench and tighten the 10mm flange bolt: tightening torque: 37.5 Lbf
(50 N.m)
3.5.4 Stator Installation
(1) Before installing a new stator, check the resistance values of the new part.
(2) Adjust the spacing between the stator and rotor.
• Insert a feeler gauge between the stator winding and the projection of the rotor.
• Rotate the rotor one complete revolution.
•
Secure the flange bolt connecting stator and front end cover. The locking torque is 7.5 Lbf (10-13
N.m)
• The correct spacing is 0.020+/-0.004 in (0.25 +/- 0.1 mm)
