Re: [DML] Alternators: Rebuilt vs Remanufactured

[dherv10@xxxx]

Group, There is a difference in a rebuilt alternator, a remanufactured 
alternator. 
A rebuilt alternator may or may not have NEW, let me say it again new parts, 
such as regulator, diodes, stator and rotor. Due to the demand for profit and 
the large chains going out for the low bid, it forces the rebuilder to cut 
corners and reuse used parts.
Yes, they take them apart, clean them up, install new bearings and while this 
is going on, someone else is checking the diodes, regulator, stator, rotor 
for reuse.
This is why test equipment has been built for it and test benches are set up 
to test the used parts. Yes, They can give you life warranty on the 
alternator, but not on the labor to reinstall. I know, when I got married 
about 6 years ago my wife had had a Pep Boys rebuilt alternator installed on 
her car. After the 3rd replacement in less than three years, I got my money 
back and had a new one built buy a Remanufacturer and the problem was solved.
ReManufacturer, This is a company that tears the alternator apart and will in 
most cases reuse the case and sometimes the rotor. But the diodes, regulator, 
brushes are replaced with new parts along with the bearings, terminals and 
other parts. If the rotor shows little to no wear on the comutator , then it 
can be turned and used again. In a lot of cases a used rotor which is the 
part that turns at about 6000 RPM's is better used then new. It already been 
spun and didn't come apart. Our new computer machine will spin them at about 
6800 RPM's for a short time.
Then you have new. All new everything.
What I'm saying is, yes some of you may have access to a rebuilder that will 
rebuild and alternator with all new parts because your asking them to do that 
or standing over them watching them. But most of you that don't and will be 
the victim as I was to the rebuilders cheap stuff out of the box at the auto 
supply stores. 
How do you think they get the price down so low and compete with each other. 
In most cases the alternators come from the same source and they use 
different color boxes. I know, I work with a remanufacturer and he has been 
in the business for 20+ years.

<< Your argument is not valid with "maybe and evaluation of whether 
they should own a DeLorean should be in question" if they decide to 
install a rebuilt alternator. What you are saying is that then 
ANYONE with ANY car should be re-evaluated in owning ANY car if they 
install a rebuilt alternator. Are you saying that anyone that owns a 
motor vehicle should not be entitled to own one if they install 
anything rebuilt? Or even a mechanic that installs re-built >>
