247k miles on original alternator and still functioning well according to a load test.

I would like to buy a quality rebuild kit for the alternator to have on hand when the time comes to refurbish it? Anyone have a source for higher quality brushes/regulator than the link below? Only want to replace it once if possible as it's not any easy drop in replacement.

Aside from brushes, regulator, and bearings, anything else that should be replaced? Are the old diodes usually ok?

Other option is to buy a Denso rebuilt alternator through Denso (OEM supplier) for approx $250, plus tax and shipping, and be done with it. Apparently,Honda discontinued alternators for these 20 year old vehicles. I've checked online Honda dealers and states "discontinued".

How many miles did your original alternator last?

Thanks for any insight!

Looks like RockAuto sells the Denso Remanufactured for a lot less once you return the core.

If you go the rebuild route, Honda might sell the brush set. TYK or SKF properly sized bearings? Not sure about the regulator. I wouldn't replace the diodes unless you had some that tested bad.

My alternator made it to ~150K miles on my TSX. I swapped it for a rebuilt alternator at local place that does that work. I didn't have time to rebuild mine.

 

Thanks PAhonda.
My plan is to buy two brushes, OEM from Honda, and a high quality aftermarket front bearing for the alternator to have on hand when the time comes to a rebuild. The front bearing should be easy to replace and it's usually the front that fails. Rear bearing doesn't have as much load.

For future reference 2005 2.4 liter:
Honda Brush OEM part number: 31140-P64-902 (make sure to get two brushes)
Bearing size info:

• Bearing: 53514 15x35x13mm rear bearing
• Bearing: 54700 17x47x14mm front bearing

Local bearing supply store has the front bearing, Koyo ( 6303 2RS ), approx $17
