Does anyone have a good part number or description for the three screws that hold down the alternator cover? The fiche says 93700-050-160A. That's what I ordered from honda but the the thread pitch was wrong.
Thanks.

Alternator cover screws
JIS referes to the head slot, so not really the issue. I just measured the screw and its 12MM x 5MM x 0.9 pitch. So, you say that you retapped it to 1.0 pitch?OldStan wrote:The originals that size (5mm) are a JIS thread different, than current metric bolts, no longer available from Honda. Someone else might have a source for them. I retapped to the current pitch (I went from the back side to get maximum thread) and it seems to work fine.
JIS also refers to the pitch, just on some sizes the pitch is the same. 6mm and 8mm are the same, 5mm, 10mm & 12mm I believe are different.
Yes, I retapped it to the standard thread. You do loose some thread, but it's not something that has a lot of pressure on it. I got the idea from someone else on the forum.

Another thought, most tap and die sets have both the M5x.8 and M5x.9 die for some reason, and I have successfully "converted" new .8 pitch screws to .9. As OldStan said, not much stress on that part either way. This way though, you don't modify an original part and I'm not sure if that's important.
