Hi Bob,


How can I make your attachments print larger.... I can't hardly see them (old fart ~ lol)


Please advise




Download them to your computer and then open with the latest version of Adobe. Then you can zoom in and enlarge them. Then they will print. If this does not work let me know and I will try something different.

Hi Bob,


I tried that but it still printed small even though I had increased the size. However I was able to read them on the computer. I have a question on what the snow/ice shield is and how do I remove? Is this the plastic cover over the fan? It looked like to me that I would have to remove the fan?


Please Advise




Yes that is the plastic cover I beleive. You referring to the fan blade? You should not have to remove that.



  • Be sure the battery connections are not reversed, this will damage the generator.
  • Do not use a high-voltage tester such as a megger, it will damage the voltage regulator/ brush holder assembly.
  • Remember that battery positive voltage is always present at generator Terminal B.



  1. Disconnect the negative battery cable.
  2. Remove the snow/ice shield and the fresh air inlet tube.
  3. Remove the generator, referring to REMOVAL NOTE.
  4. Inspect all parts and repair or replace if necessary.
  5. Install in reverse order of removal, referring to INSTALLATION NOTE.


  1. Disconnect the voltage regulator/brush holder assembly harness connector.
  2. Remove the harness connector bracket.
  3. Disconnect the Terminal B wire.
  4. Loosen the drive belt tensioner and remove the drive belt.
  5. Remove the generator bolts.
  6. Remove the generator.


  1. Install the generator.

Tightening torque:
40 - 54 N.m (4.1 - 5.5 kgf.m, 30 - 40 ft.lbf)

  1. Connect Terminal B wire.

Tightening torque:
9.0 - 12.0 N.m (0.91 - 1.22 kgf.m, 6.6 - 9.0 ft.lbf)

  1. Connect the harness connector to the voltage regulator / brush holder assembly.

Alright Bob, I was able to copy those and put them in WORD. Could you do the same for the serpentine belt. And is there any directions on how to remove the shield? If I can get these two things I should be able to stop bugging you ~ Thanks!

I forgot the belt. You are not bugging me at all. Unfortunately there are no removal and installation instructions for the shield. Please let me know if I can help further.

  1. Loosen the drive belt tension by lifting the tensioner pulley in the counterclockwise direction.
  2. Remove and replace the drive belt.
