Nissan AltimaReplacing the alternator takes 20 to 30 minutes.
Replacing the generator is quick. Loosen the fan belt, remove the generator adjustment bolts, remove the generator wiring (remember the color of the wires to avoid incorrect connections during installation), remove the generator bracket bolts, remove the old generator and tap the new generator. Just install the opposite. program.
It usually takes no more than 30 minutes, and the fastest only takes 20 minutes. It depends on the skill of the repairer. If it's difficult to remove the bolts, it won't be finished for several. hours.
To disassemble and assemble the Teana V6 generator, you must first remove the generator belt, then remove the generator mounting screws.
1. Remove the drive belt.
2. Loosen the fixing screw. The details are shown in the figure below:
3. Remove the generator by shaking it.
4. Use mounting screws to secure the new generator.
5. After fixing, install the drive belt and you're done.
Operating Procedures:
1. Before starting, check whether there is enough oil in the fuel tank and whether there is any oil leaking in each oil pipe and joint. ; Is the quantity of water in the cooling system sufficient, clean and leak-free? Is the fan belt tight enough? Check that the transmission parts of the internal combustion engine and generator should be reliably connected, the output line wires should be well insulated, and all instruments should be complete and efficient.
2. After starting, it should run at low speed fort 3 to 5 minutes. The operation can only be started after the oil temperature and pressure are normal. There should be no abnormal noise when the generator accelerates, the slip ring and commutator brushes should be in good contact, and there should be no jumps or sparks. After the operation is stable and the frequency and voltage reach the rated values, power can be supplied externally.
3. When abnormal noise, odor, sharp increase in water temperature, sharp drop in oil pressure, etc. occur. occur during operation, the machine should be stopped immediately for inspection and troubleshooting.
4. The generator power factor should not exceed 0.95 in late phase (lag). The variation range of the frequency value should not exceed 0.5 Hz.
5. Before stopping, you must first turn off the main switches of theeach power branch, gradually reduce the load, then turn off the main power switch of the generator and return the excitation rheostat to the maximum resistance position to reduce the voltage to the minimum value, then turn off the power switch excitation and the neutral point grounding switch, and finally stop the operation of the internal combustion engine.
