I replaced my single pulley alternator w/ a dual pulley alternator (the only alternator they had that would fit my car), and as a result, my belt runs at a very slight slant (what i mean is, it's a little bit further forward than it was before). Will this affect anything, or is this arrangement okay? Thanks again for your help, Robert. countchocula@forpresident.com |

Also not doing the belt any favors. Do you have your single pulley? Option #1 would be to swap the pulleys. Option #2 would be to find the crank and water pump pulleys to match your new alternator. Option #3 would be to shim the old pulleys. Gilly tlg225ccr@aol.com |

: I replaced my single pulley alternator w/ a : dual pulley alternator (the only alternator : they had that would fit my car), I *NEVER* use "remanufactured" parts from the parts store. My experience with them over the years has been so awful, from so many sources, that I find it far cheaper and much more effective in the long run to take the time and effort to obtain a properly-repaired ("rebuilt") item done by a competent independent technician. The factory-reman starters, alternators, carburetors, etc. are usually thrown-together junk made with parts from six or seven different originals and put together with low-quality replaceable/wear parts. I find that "lifetime warranty" just means you get to spend your "lifetime" returning parts under "warranty" and getting hassled by the counterman at the parts store. No thanks! : : result, my belt runs at a very slight slant Sounds like you put the belt on the foreward belt groove. When using a dual-pulley alternator on a car that came with a single-pulley unit, the REAR groove is the correct one. : : is this arrangement okay? No. You're going to lose your belt in a hurry. If putting the belt on the rear groove doesn't fix it, the alternator wasn't assembled correctly. Don't count on an exchange replacement being assembled correctly, either. DS redbear@vrx.net |

I would take a measurment first, remove the pulleys and swap the single groove over to the new unit. ( a good independant parts store with a small shop can do this or a decent auto repair garage) If both grooves on the double pulley do not line-up correctly, I would say the pulley is not pressed completly onto the shaft. Here again, I would pull it off and do some checking before tring to push it on "deeper". DD |

When I went to the 61 amp alternator all I could find was the double pulley type. I ran the car like this for years with the belt on the back groove of the pulley. This gave the best alignment. I think I changed 1 belt and 1 alternator in 5 years and this was my daily transportation. The 61 amp worked better with A/C and electronic ignition. mwhiteho@hotmail.com |
