Assembly instructions for System 71 53 799 AC

Version 22.10.2007 
You should have received those parts:
  • stator unit (preassembled)
  • rotor, spacer/washer
  • AC-regulator
  • ignition coil and high tension cable

  • cables: red, brown, blue

  • cable binders

  • 3 screws M5x20
To disengage your new rotor again, you will need a puller M27x1,25 (part 99 99 799 00).

Note: never use a claw puller, a hammer or any other device, that will shake the magnets off.
Make sure your Husquarna rests securely, preferably on an elevated work bench and that you have good access to the dynamo side of the engine. 
Disconnect all wires to the old magneto and take those parts off.
Keep the woodruff key in place, it will be used.

With the old magneto completely off, check that the new flywheel can be set fully onto the shaft with the original woodruff key present. If the flywheel does not sit fully, you may have to take a little material off the key. It should fit, but better check before you assemble.
Place the preassembled stator unit onto the engine case. The thick black coil shows backwards. Set the 3 holder screws in a middle position into the long holes to allow for adjustment.

Attention: There is no reason to remove the stator from its mounting plate. But if you do remove it, please make sure not to squeeze any wires under it.
Put the new rotor on. Make sure that it comes to sit fully on the shafts taper (watch out for the woodruff key).

Put the spacer/washer and than the original fastening nut and fasten the rotor carefully.

To disengage your new rotor again, you will need a puller M27x1,25 (part 99 99 799 00).
If you want to verify and change timing, which you may liberally do by moving the stator unit in its long holes, you should know that ignition always happens the moment the marking on the rotor's circumference is at height of the small red marking at the base plate as shown here.
Fasten the new electronic rectifier/regulator and ignition coil at an convenient place. Before you fix the coil, screw in the high-tension cables. Lay the new generator cables along the frame (using the enclosed cable binders), in that way, that they finished close to the regulator resp. ignition coil. Take care that nothing's pinched.
