Removal, repair and generator installation
Withdrawal PERFORMANCE ORDER | 1. Disconnect the negative battery terminal. | 2. Remove the cap from the terminal to the generator. | 3. Remove the nut fastening wires to the terminals of the generator. | 4. Remove the wire from the terminal to the generator. | | 5. Disconnect the generator. | | 6. Loosen the pivot bolt B for the generator and the mounting bolts A tensioning mechanism. | 7. Turn the adjusting bolt C, loosen the tension of the alternator drive belt. | 8. Remove the drive belt from the alternator pulley. | 9. Remove the bolt tensioner. | 10. Remove the hinge bolt of the generator. | 11. Loosen the bolt of the adjustment bracket and rotate the bracket. | 12. Remove the generator from the engine. |

Dismantling A warning Replace the jaws soft protectors to avoid damage to the generator components.
Check rotor PERFORMANCE ORDER | | 1. An ohmmeter measure resistance between contact rings. If the resistance is not correct, replace the rotor. Resistance: 3.5-4.5 ohms | | 2. An ohmmeter check up conductivity between the contact ring and the anchor of the rotor. In the presence of conductivity replace the rotor. | 3. If the surface of the contact ring has a roughness or traces of wear and tear, strip it with sandpaper. |
|
Checking the stator PERFORMANCE ORDER | 1. An ohmmeter check up conductivity between the wires of the stator coils. | | 2. In the absence of conductivity, replace the stator. | 3. An ohmmeter check up conductivity between the stator coils. | | 4. In the presence of conductivity, replace the stator. |
|
Check rectifier unit Negative (Black) | Positive (red) | Conductivity | E | Pn, P1, P2, P3 | 0 | B | Pn, P1, P2, P3 | X | T | Pn, P1, P2, P3 | X | Pn, P1, P2, P3 | E | X | B | 0 | Pn, P2, P3 | T | 0 | Pn | T | X |
PERFORMANCE ORDER | | 1. An ohmmeter check up conductivity between the terminals of each diode. | | 2. If necessary, replace the rectifier. |
|
Check bearings PERFORMANCE ORDER | 1. Check bearings for smooth rotation, no jamming and noise during rotation, and play. | | 2. If there are any defects, replace the bearing. |
|
Assembly Setting PERFORMANCE ORDER | 1. Place the generator on the engine. | 2. Screw but do not tighten the hinge bolt of the generator. | 3. Turn the bracket to its original position. | 4. Install the tensioner on the bracket. | 5. Screw but do not tighten the bolt tensioner. | 6. Install the alternator drive belt on alternator pulley. | | 7. Turn the adjusting bolt C, adjust the tension of the alternator drive belt. Deflection alternator drive belt New 5.5-7.0 mm Second hand 6.0-7.0 mm
| | 8. Tighten the bolt pad adjusting plate. Torque: 19-26 N ??? m | 9. Tighten the pivot bolt and bolt bracket. Torque: 38-51 N ??? m | 10. Connect the generator connectors L and S. | 11. Connect a wire to the terminals of the generator. | 12. Secure the nut at terminal B. | 13. Close the terminal in the generator protective cap. | 14. Install the air inlet and fix its collar. | 15. Install the intake of fresh air. | 16. Replace the front bolts intake of fresh air. | 17. Connect the cable to the negative terminal of the battery. | A warning Make sure the battery cables are correctly connected.
Do not use high-voltage devices, such as a megohmmeter to check for resistance.
Remember that the battery voltage is always applied to the terminals of the alternator.
Do not connect to "weight" contact L for the engine.
Do not start the engine, while the contacts L and S are disconnected from the generator.
