    Need the 3 small Phillips head screws that hold the seal mount to cap spring.

    Anyone have a size or thread pitch.

    Thx.

    Forgot to measure the diameter of the couple I took out, very small, but the ones I have are not screw threads so to speak but are a somewhat coarse thread self taping type screw. What I would call a "sheet metal" screw. Length under head is about 7 to 8 mm.

    If it was me I would take cap to hardware store and try a few screws till I found one that fit. Or it you have a motorcycle junk yard near you start looking there.

    I might try a computer fix it store or look inside an old desk top computer they tend to use a bunch of really fine screws about that size.

    You'll find them easily at any HW store (at least in the U.S.) , too big for comp store. But the length will probably be wrong. This is where a Dremel too with reinforced cutoff wheel is very useful. After cutting, file a very slight bevel around the end.

    Screw size and length is encoded into some Yamaha part numbers, which might help sometime.

    If you have a real good HW store nearby you can try this:

    Always save ALL your old parts.

    I came up with 3mm by 7.5mm and they are a self tapping sheet metal screw.
