Alternator - New / reburbished

Guys,

My alternator is dead. Lots of other threads on here describe all my symptoms. No need to go into them.......

1) Rovers North has a new one for $229 + Shipping

2) I removed my current one, and dropped my old one off at a reputable shop in the area that repairs alternators. They are getting me a price. It is my original alternator - 16 years old. I have friends say that if you get something re-built and refurbished it is really as good as new.

I have not gotten a price back yet - should tomorrow.

Question:
1) If the shop says they can re-build / refurbish my existing alternator, is that an OK thing to do?

2) What we be the cost point when I should just go with a new one?

Thanks for your opinions!

FLAGG

find a oem magnito merelli [sic] or have yours rebuilt. The new ones are junk in my experience.

I wouldn't recommend a rebuilt Marelli. It appears that OE Marelli parts are not available to consumers, what you'll get are chinese fakes. Ask me how I know.
However, if the ONLY issue is bad bearings, then it would probably be OK to repair it.

Even worse on the rebuilts, sometimes they just don't replace things. Just dealt with a bad regulator in a NAPA rebuilt unit that I got a year ago. Regulator had a date stamp of 1994 on it! Was able to track down a new regulator finally, just wasn't going to put in a third NAPA alternator after 2 going dead in two years (First one they swapped under warranty).

Rebuilt may be difficult as last I checked they stopped providing the genuine kit to the rebuilders to do this. I even went as far as to give them the CATerpillar kit number that is a drop in, but I ended up giving up and buying new. I think I have all the caterpillar alternator numbers in my thread (I could be wrong though) but you could always buy new now and have your old one rebuilt to resell or as a spare as this process always takes a week or so it seems.

That's ironic about the CAT part number. When I was searching for parts for mine, it seemed that the IF series alternators were always listed for Ford or Allis Chalmers tractors of all things.

I got one from will tillery I think its for a chebby works fine.
I also had the stocker from my 91 Classic rebuilt and the guy was able to up it to 110 amps I believe. Cost was cheap, I have not tried it on the Defender yet.

Will had nothing when I called, so I went to his source. May save you a few bucks.

Bought the amp from Action Alternator and Starter, Inc. which is the company Will Tillery uses.
They had the stock 85 and 100 AMP versions as well as a 140 AMP version that people have been running in their Defenders and Discos, which I bought.

Good luck, Flagg.

FWIW, it may be a better idea to start looking to adapt a very common alternator as we do with the series trucks. The oem's are just going to get more expensive and harder to find, rebuilts these days can be hit or miss. Plus it's a benefit to have an alternator that is on the shelf at any auto parts store and is available in a variety of outputs.

Just for your own shopping pleasure the pictured item in the above link is your standard issue Delco CS 130. You can get these in high output up to 220 amps. Usually you see them in their standard 130 A form. I found one at ASP Wholesale in 220A form for $198.20. I have used them before to get parts. I'd buy from them. The 220 puts out 115A at idle. Wow. Welding anyone?
They are a Freightliner OE alternator.

------ Follow up post added September 16th, 2011 10:31 AM ------

If you can find a blown CS 130 that is rebuildable, the same source has a 220 amp rebuild kit for about 105 clams/

"find a oem magnito merelli [sic] or have yours rebuilt. The new ones are junk in my experience."

-------------------------------

Just FYI.

I ordered a pro-line unit from Rover's north. A day later I got an E-mail that they were out of stock - and felt really bad about it - but they had a re-built oem magnito merelli alternator on the shelf that they would send for the same price with the same warranty ($229 / 1 year). They said you will not be able to tell that this one is not new. They said new this is like an $700-$800 part.

I took it. So now I am getting a re-built original. I think that is a better deal..........

Bottom line - I am hoping to have my truck back on the road next week

I took mine to a reputable shop in Denver and it was less than $50 to have it completely rebuilt and it's been bulletproof.

Update:

New Alternator installed. Engine starting, and sounding better than ever. I think my alternator had been chirping and making noises for well over a year now.......I forgot how quiet and smooth the engine could sound.

Got a rebuilt Bosch under $200 for a 4.6 on eBay. Works fine.
