Hey Guys and Gals:
The pulley on my alternator is worn down to sharp edges, and consequently have been through two sets of belts in a 6 month period. Any suggestions on where is the best place to find a replacement pulley or do any of you have one you might want to part with? Also, how hard is it to change this out. It looks like there is only one large nut holding it on, but I assume there is a keyway or something else that holds it in place? It is on my 80 Eagle. Large alternator. |

Buddy,what belts are you using it uses Dayco 3VX450 belts (3)and if your pulley on the alternator is bad the one on the pillar block is probably bad also.
Several guys on the Eagles board have removed the 300 amp and will have what you need
good luck |

Luvrbus,
The belts that came off were NAPA 7430. I looked at the pillar block pulley, and it seems to be OK. Good separation of the belts with no sharp edges, etc. On the alternator pulley, they have worn down so much that the space between the belts is negligible and they are sharp with some chips, etc. The belts actually touch so it is worn out.
BTW, how do you change out the 300A alternator. Is this a large process and how is it done? Do you use a standard size auto alternator. If so, I had some brackets on the bus that ran a rear AC unit, and pulled off the camshaft pulley. I dont use it since I removed the rear AC. Could I modify those brackets and use a regular alternator? Very little of what I have in the bus is 12V, mostly lights, etc. Is this a difficult thing to change out? |

Buddy, tell me the model and make of your alternator and I will try and find the pulley.
Eagle 10's had 2 different alternators Delco and Leece/Neville |

Buddy,
Leece Neville/Motorola makes many one wire truck alternators that are inexpensive and will work fine on your 12 volt. New around $175 and rebuilt under $100. 90 to 150 amp ratings are common.
Typically one or two belts will match the pulleys on your accessory drive to the new alternator and run one wire to the batterys and you are set.
If you go used, be sure to check the regulator for the proper part number, some are used in different ways. |
