Best Replacement Alternator for 88 GT V-6 5-Speed (Page 2/2) Patrick DEC 03, 03:35 AM quote Originally posted by theogre: To tighten, If all parts are Clean, a strap wrench around the pulley can hold for final torquing. If wrench have replaceable straps put a piece of a belt there to grab the pulley easier. Or put short section of belt between the pulley & strap. Tape the ends to keep it in place easier. Holding the pulley is one thing... but what stops the rotor from spinning. It's not like the pulley is keyed to the rotor shaft. theogre DEC 03, 10:45 AM quote Originally posted by Patrick: Holding the pulley is one thing... but what stops the rotor from spinning. It's not like the pulley is keyed to the rotor shaft. The pulley flat section rubs on other parts that can bind it to tighten it. While many ignore warnings, they just stuff a screwdriver etc in the case to lock the coil assem. If you try that use something that will not damage either coil when you hit them. Just Scraping the insulation can haunt you days, weeks to months later. Is Relatively easy to spit the case & use workmate, strap wrench, etc, to hold the coil but most won't do this for different reasons. For many just adds too much work & want the "easy fix." sleek fiero DEC 03, 10:51 AM My alternator has an allen slot in the end of the shaft so I just put a boxend on the nut and used allen socket and ratchet to torque the nut . sleek Patrick DEC 03, 11:54 AM quote Originally posted by sleek fiero: My alternator has an allen slot in the end of the shaft... Do they all have that? I'll have to take a closer look at some of the old alternators I have kicking around here! sleek fiero DEC 03, 03:04 PM They don't all have that but some do. Mine is an AC Delco. sleek sleek fiero DEC 03, 03:08 PM See some do some don't. Patrick DEC 03, 06:19 PM quote Originally posted by sleek fiero: They don't all have that but some do. I don't know whether my ACDelco unit does or not... but knowing that some don't, then my earlier question applies more so to those alternators. css9450 DEC 04, 08:38 AM quote Originally posted by ZaraSpOOk: I bought the new Remy from Rock AUto, when I took the old one out I was surprised to see the pulley was one rib larger and since the Remy also has the larger pulley I can't swap them. But since the larger pulley has worked for 35 years I just put in the Remy with the larger pulley. I'm really living dangerously, the belt looked fine so I haven't bothered putting in the new belt either. My car has had the one-rib-larger pulley ever since the last time I replaced my alternator.... Probably about 18 years now. I've had no issues.
