More alternator questions

[Don Bradner]

I decided to replace both of my alternators with a new, matched pair. I still
haven't pulled the one by the bumper, but I know the other was only 130 amps and
I want to get back to spec.

My choice was the Leece-Neville triple-nickel common truck alternator in the
160-amp version, 110-555JHO (also known as 8LHA2070VE). I debated going up to
the latest version, which is a 170-amp 110-775 that has a higher heat rating.
Prior to 2004, the 555 was rated to 200 degrees, while the 555JHO is rated to
220 degrees and the new 775 is rated to 230 degrees. I have some suspicion that
failures may partly be due to the high heat of the 8V92, but I'm thinking the
extra 20 degrees may be enough, and the price difference for 10 degrees more is
too much.

Online from http://www.fleetsource.com the 555JHO is $171 plus shipping. I prefer to
buy local if they are in the ballpark, and my local auto-electric folks came in
at $211 which was good enough for me. They hit three of their sources, all of
whom had it in stock, before arriving at that as the best price; my tellling
them that Fleetsource was $171 probably helped them not stop at the first one.

They should be here in a couple of days.
