Replacing alternator. Chain reaction?

Post by abenadam »



Based on the listing from here there is a new alternator model 31100-MCA-S41, instead of the original one - 31100-MCA-A61. Does it require new "Gear Assy, Alternator Driven (27T)" part 17 from here https://www.mrcycles.com/oemparts/a/hon ... drive-gear or it is possible to use the original one? If not, it looks like it might cause to chain reaction as part 1, "Gear, Alternator Drive (74T)" seems require replacement too. Am I wrong or there are other surprises?

the 2006 thru 2017 can all use the same alternator,
Honda loves to change part numbers for no damn good reason.

I have a 2002 and initially intended to order a later year model, with more amperage, but in a dumb dumb moment, I ordered the 2002 year model from Partzilla....

guess it don't matter, I don't have any extra lights at all.

If your alternator has failed, you will want to replace it with 31100-MCA-S41. Be sure to buy an OEM Honda one that comes in Honda package. If you order from the web page link you posted, that is what you will get. It should mate up just fine with your current alternator drive gear. As for the alternator drive gear, unless it has an issue too, nothing will need done to fit a new alternator to it.

An eBay alternator caused this. Here is more of the story. See post #12.

Warning to all, only use OEM alternators, starters, and starter relays on 5th gen GoldWings.

Actually, I bought it directly from "DB Electrical", but point is correct - OEM only

DB Electrical is a huge eBay seller for GW alternators, and it is where most get them from.
