Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 2005alternator kit?
I remember years ago when I was in college walking into Pep Boys and seeing behind the counter a bunch of vacuum packed cards of alternator bearings, brushes, diodes, etc. assembled into a little "alternator rebuild kit." Well now I finally have an alternator that still works good but has a noisy drive end bearing. Rather than s**tcan it I was just going to get a kit and give it a freshen up. None of my local FLAPS stock alternator parts anymore... where do you get this kind of stuff nowadays? The thing that REALLY pisses me off is that I just bought a near-new "rebuilt" 10SI from a guy I know for a cheap price, I was just going to throw that in and use it (as it probably cost me less, adjusted for inflation, than the last "rebuild kit" I bought, years ago.) Well it had to be reclocked for my app, and when I went to reclock it, the second or third case bolt I tightened down snapped off in the front part of the housing. I was just snugging it up with a nutdriver too, not even using a ratchet! what a load of crap. It's not my friend's fault, it still looks brand new and all the hardware is shiny and cad plated, it's just shite. I set it down and walked away from it, as if I'd kept messing with it it would have undoubtedly gone through the windshield of my car. So I need to get some new case bolts to use that one... which I can probably get, but not until Saturday... makes me suspect the quality of regulator and bearings used in it too, so perhaps I ought to kit that one as well... grr... nate  Signaturereplace "fly" with "com" to reply. http://home.comcast.net/~njnagel > I remember years ago when I was in college walking into Pep Boys and > seeing behind the counter a bunch of vacuum packed cards of alternator [quoted text clipped - 24 lines] > > nate Oh, meant to ask one more question. Both of the 10SIs that I have are "one wire" units, not by my choice, one came with the car and the other was cheap enough I didn't bitch. The question is this, can you hook up a one-wire unit as a three-wire without damaging the regulator? I would really like to have the wiring in place should I ever need to do a quick field replacement in some out of the way locale, but it seems that conversions from one to three wires are not anywhere near as common as the other way around. In any case I like the way the three wire remote senses voltage; in my case there's an ammeter in the dash so it's a long way from the alternator to the starter solenoid and that feature could be quite useful as I haven't measured but I'm sure there's at least a few tenths of a volt drop between the alternator and the battery post. Or, obviously, if someone can tell me where to find a "rebuild kit" for cheap I will convert one of them back to a three wire and not worry about it any more. nate (now about here's where I'd say that I'd expect E----- S------ to make some comment about homemade wiring harnesses and extra wires, were I the type to make snarky comments like that... just for the record this is not a homemade harness, just a home repaired and modified one <G>) Signaturereplace "fly" with "com" to reply. http://home.comcast.net/~njnagel > > I remember years ago when I was in college walking into Pep Boys and > > seeing behind the counter a bunch of vacuum packed cards of alternator [quoted text clipped - 4 lines] > > FLAPS stock alternator parts anymore... where do you get this kind of > > stuff nowadays? I generally buy my rebuild parts from a local alternator/ generator repair shop, they're friendly reasonably priced, and easy to do business with. I usually have them press in any bearings that are pressed into the case. I also see that http://www.rockauto.com carries parts as well at very reasonable prices. I've dealt with them in the past and the only glitch was Delco brand suspension bushings took two weeks to get.

Sometimes an alternator shop will sell them to you. The last time I bought them, it was from a mechanics quality parts outlet, not a franchise place. But that has been a long time. For most alternators, it is not rocket science to rebuild them. Up here in Canada we can still get he kits from Canadian Tire. I have one here in my off road spares kit that fits a 10SI, 12SI, 15SI and 17SI.

When you disassemble, the rotor comes out with the end bell. Most of my experience is with Delco alternators and the bearing is retained by a metal plate on the inside. To get to the screws that hold this retainer plate, you must press the rotor shaft out of the bearing. This is tough to do without damaging the alum. cast end bell. You need split bearing puller plate to go between the end bell and the rotor, then a two or three leg puller or arbor press. If I have noisy front bearing, I take it to the shop or get a rebuilt one. However, these are becoming even harder to find. Replacement, new alternators are all that the parts stores now have.

I haven't checked in a while, but I'd think that NAPA and Car Quest would both still sell the individual components. Pardon if I'm wrong; hth, otherwise. s > I remember years ago when I was in college walking into Pep Boys and > seeing behind the counter a bunch of vacuum packed cards of alternator > bearings, brushes, diodes, etc. assembled into a little "alternator > rebuild kit."

I was afraid someone would say that... problem is, the only one I know of is in Annapolis, and honestly, I have ZERO free time during the average week during normal business hours (and they're not open on Saturday.) It sucks; I'm pretty much limited to the chain parts stores.... On the upside, I found a CarQuest near my office. This is a Good Thing(tm) as the only NAPA I know of is also in Annapolis. I obviously haven't tried them yet as I haven't been to work since Friday so maybe they will come through for me. >> second or third case bolt I tightened down snapped off in the front >> part of the housing.

Eh, it was still worth what I paid for it as a core, just needs more work than I was hoping for... nate Signaturereplace "fly" with "com" to reply. http://home.comcast.net/~njnagel >I remember years ago when I was in college walking into Pep Boys and >seeing behind the counter a bunch of vacuum packed cards of alternator [quoted text clipped - 4 lines] >FLAPS stock alternator parts anymore... where do you get this kind of >stuff nowadays? Try an industrial bearing supplier. Pull the bearing out, take it in and ask them for a match. Try the yellow pages under "bearings" or see if there is a local branch of Applied Industrial Technologies in your area. >The thing that REALLY pisses me off is that I just bought a near-new >"rebuilt" 10SI from a guy I know for a cheap price, I was just going to [quoted text clipped - 11 lines] >quality of regulator and bearings used in it too, so perhaps I ought to >kit that one as well... Try a local industrial fastener place for bolts.... and ask for stainless. --scott Signature"C'est un Nagra. C'est suisse, et tres, tres precis." |
