Removal

1. Remove the rider's seat.

2. Daytona 675 only: Remove the left hand lower fairing.

3. Disconnect the battery, negative (black) lead first.

4. Release the bolts securing the left hand engine cover, noting the position of the copper washer under the head of one of the upper bolts. Collect the solenoid/fairing bracket from under the front two bolts.

  1. Left hand engine cover
  2. Copper washer position
  3. Solenoid/fairing bracket

5. Withdraw the cover from the crankcase against the pull of the alternator magnet.

Note:

6. To remove the stator and crankshaft position sensor from the cover, release the three bolts in the centre of the cover and release the bolt securing the cable bracket. Discard the bolts.

7. Release and discard the fixings securing the crankshaft position sensor to the cover.

Alternator

  1. Stator
  2. Stator fixings
  3. Crankshaft position sensor
  4. Crankshaft position sensor fixings
  5. Cable bracket
  6. Cable bracket fixing

8. Withdraw the stator and crankshaft position sensor.

Caution: Do not use tools to tighten service tool T3880375.

Tighten the tool by hand only. Over-tightening of the tool will lead to damage to the alternator rotor.

9. To remove the rotor, clean the alternator rotor to remove all traces of oil, and fit tool T3880375 to the rotor as shown below. Retain the tool to prevent the crankshaft from rotating and remove the centre bolt from the crankshaft.

Alternator

  1. Rotor
  2. Tool T3880375
  3. Centre bolt

10. With the bolt removed, locate the spigot from the larger of the two thrust pads supplied with tool T3880365 to the crankshaft.

Alternator

  1. Thrust pad

11. Assemble tool T3880365 to the threaded centre section of the rotor.

Note:

12. Hold the centre of the tool to prevent rotation then tighten the draw-bolt in the centre of the tool to release the taper seating of the rotor from the crankshaft.

Alternator

  1. Rotor
  2. Tool T3880365

13. Withdraw the rotor and tool as an assembly and then separate the tool from the rotor. Collect the Woodruff Key and the tool thrust pad from the crankshaft.

Assembly

1. Refit the Woodruff key to the crankshaft.

2. Assemble the rotor to the keyway on the crankshaft, ensuring the Woodruff key remains in position.

Caution: Do not use tools to tighten service tool T3880375.

Tighten the tool by hand only. Over-tightening of the tool will lead to damage to the alternator rotor.

3. Refit tool T3880375 to prevent the crankshaft from rotating, ensuring the rotor is free from oil and the tool is not over-tightened.

4. Tighten the rotor retaining bolt to 120 Nm

5. Remove tool T3880375.

6. Locate the stator and crankshaft position sensor to the engine cover.

7. Apply silicone sealer to the cable grommet (at the factory, ThreeBond 1215 is used) and align the cable to the exit slot.

8. Fit the cable retainer bracket and tighten a new retainer bolt to 6 Nm.

9. Tighten the new stator bolts to 12 Nm.

10. Tighten the new crankshaft position sensor bolts to 6 Nm.

11. Position a new gasket to the crankcase dowels then refit the left hand engine cover.

12. Ensure the bolt with the copper washer is correctly located. Refit the solenoid/fairing bracket to the front two bolts. Tighten the cover bolts to 9 Nm.

Alternator

  1. Left hand engine cover
  2. Copper washer position
  3. Solenoid bracket

13. Daytona 675 only: Refit the left hand lower fairing.

14. Reconnect the battery, positive (red) lead first.

15. Refit the seat.

Alternator Rectifier

The rectifier does not contain any serviceable parts and must be replaced if faulty.

Daytona 675 up to VIN 381274, Street Triple and Street Triple R all VINs

The alternator rectifier is located in between the rear suspension unit and the gearbox. To access the rectifier connector, remove the fuel tank.

Daytona 675 from VIN 381275

The alternator rectifier is located under the cockpit's right hand infill panel. To access the rectifier, remove the right hand lower fairing.

Alternator Stator

The stator is an assembly of 18 coils, arranged into three phases. It is possible to check for continuity, and short circuits through the coils to earth.

Rectifier/ Regulator

Internally the rectifier/regulator consists of:

The diodes are arranged with one diode connected between each yellow input wire and each pair of red and black output wires.

The diodes convert the ac voltage to dc voltage.

Each yellow input wire is also connected to a thyristor which is in turn connected to ground. When the dc voltage at the battery reaches the required level, the voltage controller sends a signal to all three thyristors. The thyristors then conduct and effectively short circuit the stator until the dc voltage drops to an acceptable level.

It is possible for any number of these diodes to fail, reducing the power output of the unit. This may not be obvious until maximum power is required by the ignition, lighting and accessories etc.

The diodes can be checked using a multimeter on DIODE setting.
