However my question is can a YDK YV-2200 be used instead of a YDK YV-551. I think it can but would like conformation.
On DC04's, any YDK from another DC04, 7 or 14 will fit any DC04 that was originally fitted with a YDK. DC04's originally fitted with an Ametek motor will need new motor rubbers and plastic sealing ring to fit a YDK in there.
I *think* the 2200 is from a DC14 originally (we don't reference on YDK numbers), but it will fit just fine.
