Engine, General

General inspection

Make it a habit to give the engine and engine compartment a visual inspection before starting the engine and after operation once the engine has stopped. This will help you to discover quickly if anything abnormal has happened, or is about to happen.

Look especially carefully at oil, fuel and coolant leakage, loose bolts, worn or poorly tensioned drive belts, loose connections, damaged hoses and electrical cables. This inspection only takes a few minutes and can prevent serious malfunctions and expensive repairs.



WARNING

Accumulations of fuel, oil and grease on the engine or in the engine room constitute a fire hazard and must be removed as soon as they are detected.



WARNING

If an oil, fuel or coolant leak is detected, the cause must be investigated and the fault rectified before the engine is started.

WARNING

Washing with a power washer: Never aim the water jet at radiators, charge air cooler, seals, rubber hoses or electrical components.



Drive Belt, Check and Change

IMPORTANT!

Always change a belt which is oily, worn or damaged. Belts which operate in pairs must be changed together.

Inspection should be carried out after operation, when the belt is hot. It should be possible to depress the drive belt about 3-4 mm (0.12-0.16") between the pulleys.

The drive belt has an automatic belt tensioner and therefore does not need to be adjusted.


Oil level, checking and topping up

WARNINGI

Working with or approaching a running engine is a safety risk. Watch out for rotating components and hot surfaces.

When checking the oil level the vehicle should stand on level ground.

Only use a recommended grade of oil; refer to Oil recommendations.

Make sure that the oil level is between the MIN and MAX marks. Do not fill above the maximum oil level.
Oil filter, Change
Change the oil filters during each oil change.
WARNING
Hot oil and hot surfaces can cause burns.
Removal
1. Drain the oil according to the instructions in Engine 0,7, Change, page 48.
NOTICE! Position a suitable vessel underneath the filter to avoid oil spillage.
2. Clean around the oil filter.
3. Carefully remove the oil filter cover (1) and filter
4. Remove the O-ring (2) and filter (3)
5. Let the oil drip off into a collection vessel.
Installation
6. Install a new filter (3) and a new O-ring (2)
7. Install the filter cover (1) and filter Torque to: 40 Nm (29.5 lbf.ft.)
8. Fill with required volume of oil, see Engine Oil, Change, page 48. Carry out a function test
Start the engine.
Check that there is no oil leakage from the oil filter or drain nipple.
Turn off the engine.
Check the oil level after a few minutes.
Top up with oil as necessary.

Draining condensate, fuel system
1. Stop the engine and close the fuel tap.
2. Put a collection vessel under the fuel pre-filter to collect the condensate and fuel.
3. Open the drain nipple (1) at the bottom of the water separator (2).
4. Drain the water contained in the water separator into the collection vessel.
NOTICE! Do not drain the water separator completely.
5. Tighten the drain nipple and open the fuel tap.
6. Start the engine and check there is no fuel leakage from water separator.
Fuel filter, Change

WARNING

Risk of fire.

When carrying out work on the fuel system make sure the engine is cold. A fuel spill onto a hot surface or electrical components can cause a fire.

NOTICE! Do not fill the new fuel filter with fuel before assembly; there is a risk of contaminants entering the system and causing malfunctions or damage.

1. Clean round the fuel filter

2. Remove the filter (1) using a suitable filter remover. Collect any spilled fuel in a collection vessel.

3. Clean the filter mating surface on the filter bracket

4. Lubricate the seal with diesel and install the new fuel filter. Tighten the fuel filter in accordance with the instructions on the fuel filter.

5. Vent the fuel system as necessary; refer to Fuel system, bleeding.

How to Read Alarm Codes From SmartGen Genset Controller

Auto Module Control Panel is the configuration for nobody on duty controlling generators. This kind of panel adopts auto module control system, with large LCD display to show the menu, such as SmartGen controller. Features:   1. SmartGen 6110 can receive remote output signal from ATS and realize auto start and stop of generators. 2. SmartGen 6310 can realize all functions of 6110, add RS232 interface which can communicate with PC to realize remote operation.  3. SmartGen 6410 Auto Mains Failure controller, can realize all functions of 6310, furthermore can detect  ATS and control directly. The alarm of diesel generator controller is not the amount of stop alarm, which does not affect the normal operation of diesel generator. When the alarm occurs, the unit will not stop, and when the alarm conditions do not exist, the amount of warning will automatically disappear.  Today Starlight manufacturer mainly shares alarm codes for diesel generato...

How to know and solve faults of genset voltage transformer

 Today Starlight Power shares the common faults for voltage transformer of diesel generator set. Hope it is helpful to you. 1) The insulation between iron chips is damaged. Fault phenomenon: temperature rises during operation. The possible causes of the failure are: poor insulation between iron chips, bad use of environmental conditions or long-term operation under high temperature, which promote the insulation aging between iron chips. (2) Poor contact between grounding plate and iron core. Fault phenomenon: there is discharge sound between iron core and oil tank during operation. Cause of failure: the grounding plate is not inserted tightly, and the mounting screw is not tightened. (3) The iron core is loose. Fault phenomenon: abnormal vibration or noise during operation. The cause of failure: the iron core clamp is not clamped, and the iron chip is loose. (4) Turn to turn short circuit of winding. Fault phenomenon: during operation, the temperature rises, there is ...
