Re: Accord 91 Alternator job

I guess setting up a rule that says replace at XXXX number of miles or a
certain time period would likely prevent failures. Thats how Honda does it
on their new vehicles and it seems to work pretty well.

However, in the case of the charging system, I think we can be a little more
scientific.

Pull the brush assembly out of the alternator if you think that it is
surviving on borrowed time. Check the amount of brush material left. If
theres not much, replace the brushes.

In my experience, anything after 160000kms would fall into that category.
While you have it apart, inspect the bearings for wear. Any play and it
should be replaced. For the $10 or so in parts, I would say its well worth
it. Getting your battery load tested after its on 'borrowed' time is
probably not a bad idea either. Just ensuring a battery is in good shape can
prevent major failures of the charging system in the future.

Just a note that if its the first time you are pulling out your alternator,
it may take longer than it should. Now that I know what I am doing on my 98
civic, i can have it out in less than 15-20 minutes. (no exaggeration).
Disconnect the battery, jack the car up, undo the tensioner, disconnect the
power lead, unplug the harness, undo the pivot bolt, and remove the
alternator bracket attached to the engine block (2 bolts). It practically
falls out into your lap (or onto your head depending on whether you are
expecting it or not) :)

Once its out, the only trick is to ensure you have a method of removing the
pulley bolt on the alternator. Impact works really well. Then you can use
an impact screwdriver to undo the housing bolts, and your in business.
